I’m starting to think we’re pretty spoiled…

There are just so many optics companies making high-quality red dot sights, and they won’t cost you upwards of a thousand dollars anymore…

Now two of the most popular red dots out there right now are:

• The Trijicon MRO (See Price On Optics Planet – Over 240 Customer Reviews)
• The Holosun 510c (See Price On Amazon – Over 365 Reviews)

And in this Trijicon MRO Vs Holosun 510c comparison, we’re going to see how these two sights stack up against each other in the following categories…

• Durability And Toughness
• Lens Clarity And Reticle
• Battery Life And Brightness Settings
• Extra Accessories Included With The Optic
• Price Comparison

In the end, I’ll tell you which of the two sights I prefer, and you should have all the information you need to determine which optic will work best for you…

Let’s jump into it! 

Durability And Toughness…

Trijicon MRO

Trijicon is known for making extremely durable optics. The Trijicon ACOG has been used in the U.S. Military for a number of years now, and the same quality and attention to detail goes into the MRO…

Now MRO actually stands for Miniature Rifle Optic, and it’s Trijicon’s version of a micro red dot sight. It has a very tough sight housing that’s made from forged 7075-T6 aluminum…

And it’s hard anodized to help protect the optic from the elements. In addition to that, the windage and elevation turrets are recessed into the sight housing. So they can never be spun or snapped off accidentally.

The MRO is also fog proof and waterproof in up to 100 feet (30 meters) of water. So it can easily handle rainy, snowy, and wet conditions without any problems…

And it’s also shockproof, so it can handle the recoil from high-powered rifles, shotguns, and pistol caliber carbines. 

All in all, I’m very impressed with the durability and toughness of the MRO.     

Holosun 510c

The Holosun 510c is also a pretty tough red dot sight. First of all, the sight housing is made from a high strength aluminum, and the lens is protected by a sturdy titanium hood…

In addition to that, just like with the MRO, the windage and elevation turrets are recessed into the sight housing, so they won’t get accidentally spun or snapped off. 

The 510c is also fog proof and waterproof in up to 1 meter of water. So, it will also easily handle rainy, snowy, and wet conditions…

And again, just as with the MRO, the 510c is shockproof so it can handle recoil from shotguns, high-powered rifles, and pistol caliber carbines without any issues at all…

All in all, I think the Holosun 510c is also a very durable sight.  

Durability And Toughness Conclusions…

So both sights are made from high quality materials, and both have windage and elevation turrets that are recessed into the sight housing…

That being said, the MRO can be submerged in up to 30 meters of water, whereas the 510c can only be submerged in 1 meter…

In addition to that, the MRO is a micro red dot sight which just by virtue of its design is a little bit tougher than the open style reflex sight design of the 510c…

So considering all of these factors, I’m going to give the win in this category to the Trijicon MRO.

Winner: Trijicon MRO

Lens Clarity And Reticle…

Trijicon MRO

The Trijicon MRO has pretty good lens clarity. There is a distinct blue tint when looking through the sight, but the sight picture is still very crisp. 

Trijicon says the blue coating makes the lens stronger and helps you have better contrast when looking through the sight, and there is some truth to that…

Honestly, I would prefer the lens to be more clear, but that being said, it’s not too distracting and you still get a very clean sight picture when aiming through the optic.

One of the features I love about the MRO is the enlarged 25mm objective lens. This gives you a large field of view, and allows you to see more of your target and what’s around it down range. 

Seeing more when shooting is always a good thing, and as I said, the large objective lens on this sight really sets it apart from other micro red dot optics. 

Now the reticle on the MRO is a simple 2 MOA (minute of angle) dot. I think the 2 MOA dot reticle is a good choice for a red dot sight…

I like it because it’s an easy reticle for your eye to pick up quickly (which allows you to shoot fast at targets up close), but at the same time it’s small enough to give you a fair amount of precision for small targets in the distance. 

I really like it, and I’m glad that Trijicon decided to go with a 2 MOA dot rather than something larger like a 4 MOA or a 6 MOA dot. 

Last, Trijicon makes a version of the MRO with a red reticle and a version with a green reticle. I personally always prefer red on my sights and optics…

But there are a lot of people who really like green reticles, and I’m glad that Trijicon offers the MRO with reticles in both colors. 

Holosun 510c

The lens clarity on the Holosun 510c is very good. The lens is very clear, and you don’t get any of the greenish or bluish tint which is common on many other red dot sights…

In addition to that, because the 510c is a full-sized reflex sight, it has a HUGE sight window, and you get a very large field of view when aiming through the optic.

All of this allows you to get a very crisp and clean sight picture, and you’re able to see a lot of your target and what’s around it. 

Now Holosun includes a feature on the 510c called the MRS (Multiple Reticle System). Basically, this means that you have 3 reticles to choose from that are programmed into the sight.

• A 2 MOA dot
• A 2 MOA dot surrounded by a 65 MOA ring (the Circle Dot Reticle)
• A 65 MOA ring (with no dot in the center)

Like a mentioned earlier, the 2 MOA dot is a good red dot reticle, especially if you want to keep things very simple, but my favorite reticle (on a red dot sight) is the Circle Dot Reticle…

The 65 MOA ring allows you to shoot extremely fast at large targets up close, but you still have that precise 2 MOA dot in the center for small targets in the distance. 

I really love it because it’s very easy to see and intuitive to use, and it helps you shoot quicker which is what a red dot sight is designed to do. 

Additionally, you also have the 65 MOA ring (with no 2 MOA dot) reticle option. Personally, I don’t really have a need for this reticle because I feel like the circle dot does everything it does and more, but it’s there if you find a use for it. 

Last, just like with the MRO, Holosun offers a version of the 510c with red reticle options (the HS510c) and a version with green reticle options (the HE510c elite)…

…and again, I think it’s good that they give the buyer a choice between the two reticle colors.    

Lens Clarity And Reticle Conclusions…

So in this category we have some major differences between these two sights. First of all, they both have a great field of view, but that’s really where the similarities end…

The lens on the MRO has a slight blue tint, and even though it doesn’t really affect your shooting, I prefer the clear lens on the Holosun 510c. 

In addition to that, the 510c has the same 2 MOA dot as the MRO, but it also has the Circle Dot Reticle, which I think is an important upgrade because it helps you shoot faster…

So for these reasons, the Holosun 510c is the clear winner here. 

Winner: Holosun 510c

Battery Life And Brightness Settings…

Trijicon MRO

The Trijicon MRO is powered by 1 CR2032 battery, and it will keep the sight running for 5 years of continuous life (on daylight brightness setting 3)…

Ultra long battery life like this is a must-have feature for me on a red dot sight because you don’t want your optic dying on you at the wrong time. 

I’ve had red dots die on me at the range before, and it’s really annoying. But more importantly, you never want your optic dying on you if you ever need to use it in an emergency situation. 

So with 5 years worth of battery life, as long as you swap out your battery once a year, you’ll never have to worry about it dying on you.

Now with the MRO you get 8 total brightness settings: 5 daylight settings, 2 night vision settings, and 1 super bright setting.

The daylight brightness settings are very bright, and you shouldn’t have any problem seeing the reticle even on a sunny day (you also have the extra bright setting just in case the conditions are extreme). 

Most people won’t use the 2 night vision settings, but some people with night vision equipment will take advantage of them, and I’m glad that Trijicon includes them at no additional cost. 

Holosun 510c

The Holosun 510c also uses 1 CR2032 battery which is able to power the sight for around 50,000 hours (5 years)…

Like I mentioned before, I love ultra long battery life like this, and I’m happy that it’s included on the 510c…

In addition to that, the 510c includes the Holosun “Shake Awake” feature. This basically means that your optic will automatically turn off after a period of non-use…

…and automatically turn on as soon as the sight senses any motion at all (for example, when you pick up your rifle). 

I love this feature because it helps save your battery life (which is already very long), and at the same time, it keeps your sight ready to go as soon as you pick up your gun. 

Another feature on the 510c is the included solar panel. This is a really cool addition because it means you can run your sight without a battery (as long as you have some sunlight). 

I think it’s a great feature, and it’s just another method that Holosun gives you to extend the battery life on your red dot optic. 

Now the 510c includes 10 daylight brightness settings and 2 night vision settings. Just as with the MRO, the brightness settings get very bright and you shouldn’t have any problems with the reticle washing out even on a sunny day. 

And also just as with the MRO, I like that Holosun includes the 2 night vision settings on the 510c without making you pay extra to get them (the way some optics companies do).   

Battery Life And Brightness Settings Conclusions…

So in this category we have a few similarities and some major differences between these two optics. First of all, they both have great battery life and they both have a wide range of brightness settings…

However, in addition to all that, the Holosun 510c includes the “Shake Awake” feature and the solar panel which both extend the battery life on the sight even more. 

So because of that, I think the clear winner in this category is the Holosun 510c

Winner: Holosun 510c

Extra Accessories Included With The Optic…

Trijicon MRO

You can purchase the Trijicon MRO with a low mount, a lower ⅓ cowitness mount, an absolute cowitness mount, or with no mount…

…and the overall price of the optic will go up if you choose to get one of the factory mounts included with the sight. 

The lower ⅓ cowitness mount and absolute cowitness mount are both perfect for use with an AR-15 or another AR platform rifle…

…and the low mount will pair the sight nicely with a shotgun, an AK, and some pistol caliber carbines. 

Even though I wish Trijicon would include it’s mounts without raising the overall price of the optic, I am happy that the factory mounts included are very high quality.

In addition to that, because the MRO is an incredibly popular mount, there are a ton of aftermarket companies making mounts that are compatible with it…

So if you choose to purchase the MRO without a mount included, you’ll pay less money for the sight and you’ll have a wide variety of options to choose from when it comes to the mount you want to get (Quick Detach mounts, Super lightweight mounts, etc.)…

Holosun 510c

The Holosun 510c comes with some pretty cool accessories. First of all, you get an extra battery tray, a battery, and a lens cloth…

But the really exciting accessory is the included QD (Quick Detach) mount. Now, this mount is included with every 510c, and it doesn’t affect how much you’ll pay for the optic. 

It’s very high-quality, and it sets the sight up for an absolute cowitness with backup iron sights on an AR-15 (or any AR platform rifle or pistol)…

I really like this mount, but it does kind of limit you to using the 510c on an AR platform rifle…

If you’re running an AK or a shotgun (or any firearm that favors a low mount), it will mount the sight rather high, which will be less than ideal…

That being said, most people will get this optic for an AR-15, and if that’s the case for you, the included mount will work perfectly. 

Extra Accessories Conclusions…

So the Trijicon MRO really doesn’t have any included accessories (at no extra cost). If you want to get the sight at the lowest price possible, you’ll have to get it without a mount…

…but if you are willing to spend a little bit of extra mount you can get it with a low mount or with a couple of different high mounts. 

On the other hand the Holosun 510c comes with an included high mount at no extra cost. So for this category, I’m going to give the win to the Holosun 510c.  

Winner: Holosun 510c

Price Comparison…

Unfortunately I won’t be able to give exact numbers in this category because the prices of these sights are changing all the time…

That being said, in general, you’ll usually find that the Holosun 510c is around 100 to 130 bucks less expensive than the Trijicon MRO…

So the clear winner in this category is the Holosun 510c. 

Winner: Holosun 510c

Trijicon MRO Vs Holosun 510c – Final Thoughts…

So to sum it all up, in the Durability And Toughness category, I gave the win to the Trijicon MRO because it’s more waterproof and has a more durable design…

In the Lens Clarity And Reticle category, the Holosun 510c took the lead because it has a much more clear lens than the MRO, and it has the Multiple Reticle System with the Circle Dot Reticle…

In the Battery Life And Brightness Settings category, I also gave the win to the 510c because it has great battery life, the “shake awake” feature, and a solar panel…

In the Extra Accessories category, the 510c was again the winner because it comes with an absolute cowitness mount at no extra cost….

And last in the Price Comparison, once again, the 510c was the clear winner because it is much less expensive than the Trijicon MRO…

So which of these sights do I prefer? I prefer the Holosun 510c (If you’re getting it for an AR-15).

I prefer the Holosun 510c for a few reasons. First of all, it has a crystal clear lens and a huge field of view which is something that will help you shoot more effectively…

It also has the Circle Dot Reticle, which is my favorite reticle for a red dot sight because it allows you to shoot very fast, and at the same time, it doesn’t give up any precision for shooting at targets in the distance. 

In addition to that, it comes with a high quality QD mount, so you won’t have to spend extra money just to be able to mount it on your AR-15…

And last, it’s around 100 bucks less expensive than the MRO, so it will save you money. 

Now if you want an insanely tough optic or if you are mounting your optic on a firearm that favors a low mount like an AK or a shotgun, then feel free to go with the MRO because it’s still an amazing sight…

Either way, I hope I was able to show you the major similarities and differences between these two awesome red dot optics!  

The red dot market has really come a long way in recent years…

Gone are the days when you’d have to spend nearly a thousand bucks just to get a reliable optic, and that’s a great thing for us consumers…

Now two of the most popular red dot sights on the market right now are:

• The Trijicon MRO (See Price On Optics Planet – Over 240 Customer Reviews)
• The Sig Romeo 5 (See Price On Amazon – Over 1,1775 Customer Reviews)

And in this Trijicon MRO Vs Sig Romeo 5 comparison, we’re going to examine how these two sights stack up against each other in the following categories…

• Durability And Toughness
• Lens Clarity And Reticle
• Battery Life And Brightness Settings
• Size Comparison
• Extra Accessories Included With The Optic
• Price Comparison

In the end, I’ll tell you which of these two great sights I prefer, and you should have all the information you need to decide which optic will work best for you…

Lets jump into the comparison! 

Durability And Toughness…

Trijicon MRO

The Trijicon MRO is a very durable optic. Trijicon (the company) is actually known for making extremely tough optics… 

In fact, the Trijicon ACOG has been used in the U.S. Military for quite some time now, and the same quality and attention to detail goes into the MRO…

Now MRO stands for Miniature Rifle Optic, and it’s basically Trijicon’s version of a micro red dot sight…

The sight housing on the MRO is made from forged 7075-T6 Aluminum, and it has a hard anodized finish to help protect the optic from the elements…

In addition to that, the windage and elevation turrets are recessed into the sight housing, which means they can never be spun or snapped off accidentally…

The MRO is also fogproof and waterproof in up to 100 feet (30 meters) of water. So it will easily be able to handle rainy, snowy, or wet conditions. 

And it can handle recoil from high-powered rifles, shotguns, and pistol caliber carbines without any issues as well.

All in all, I’m very impressed with the durability and reliability of the Trijicon MRO. 

Sig Romeo 5

The Sig Romeo 5 is also a very durable optic. To start off with, the sight housing is made from Aircraft-Grade Aluminum, and it also has an anodized finish to help protect the optic from the elements…

The windage and elevation turrets do protrude slightly on the Romeo 5, but they sit pretty low and are protected fairly well by the sight housing (I think it’s unlikely they’ll ever get accidentally snapped off)…

In addition to that, the Romeo 5 is fog proof and waterproof in up to 1 meter of water. So it can easily handle rainy, snowy, or wet conditions…

And it’s also shockproof, so it won’t have any problems with recoil on shotguns, high-powered rifles or pistol caliber carbines…

I’ve seen some Romeo 5’s take some major abuse (including being frozen into a block of ice), and they still keep working. So their durability is also pretty impressive.  

Durability And Toughness Conclusions…

I think both of these sights are very durable and reliable. That being said, I like that the windage and elevation turrets are completely recessed into the sight housing on the MRO…

I also like that it’s rated to be submerged in up to 100 feet of water, which means you can literally take it SCUBA diving with you if you wanted to…

It’s a tough one… But even though I’m very pleased with the durability of the Sig Romeo 5, the Trijicon MRO is just a little bit tougher. So the MRO gets the slight win in this category. 

Winner: Trijicon MRO

Lens Clarity And Reticle…

Trijicon MRO

The lens clarity on the Trijicon MRO is pretty good. You do get a distinctive blue tint when looking through the sight, which is less than ideal…

Trijicon says the blueish coating increases lens durability and gives you greater contrast when looking through the optic… 

There is a little bit of truth to that, but I would, personally, prefer it to be more clear. That being said, it’s easy to ignore, and you still get a crisp and clear sight picture when looking through the sight. 

On a brighter note, the MRO has a large 25mm objective lens. This is a unique feature on a micro red dot sight, and I love it because it gives you a HUGE field of view…

You’re able to see more of your target AND what’s around it, and that’s always a beneficial thing when you’re shooting a rifle. 

Now the reticle on the MRO is a simple 2 MOA (minute of angle) dot. I think a 2 MOA dot is a great reticle for a red dot sight…

I like it because your eye can quickly and easily pick up the dot when you need to make fast shots at targets up close…

But at the same time, the dot is small enough to give you a fair amount of precision when shooting at small targets in the distance. 

Overall, I’m glad that Trijicon chose to go with a 2 MOA dot rather than something larger like a 4 or 6 MOA dot because they’re simply not as precise. 

Sig Romeo 5

The lens clarity on the Sig Romeo 5 is very good. The lens is extremely clear, and you don’t see any of the greenish or bluish tint that you sometimes find on other red dot sights…

The 20mm objective lens is smaller than the MRO’s objective lens, so it doesn’t have quite as large of a field of view…

…but you can still see a lot through the sight (and you get a very clear sight picture), so it doesn’t really have a negative impact on your shooting. 

The reticle on the Romeo 5 is also a simple 2 MOA dot. Like I mentioned earlier, I really like the 2 MOA dot reticle on a red dot sight because it’s simple, fast, and precise. 

Lens Clarity And Reticle Conclusions…

So in this category, we have a few important differences between these sights. First of all, the MRO has a blue tint when looking through the optic, whereas the Romeo 5 is very clear (which I prefer).

But on the other hand, the 25mm objective lens is a unique feature on the MRO and gives you an extended field of view over the 20mm objective lens of the Romeo 5 (which is what most micro red dot sights have)…

They both have positive and negative features that kind of balance out in this category, and since they both have the same 2 MOA dot reticle, I think the right thing to do here is call it a draw. 

Winner: DRAW

Battery Life and Brightness Settings…

Trijicon MRO

The Trijicon MRO uses 1 CR2032 battery which is able to power the sight for 5 continuous years (on daylight brightness setting 3)…

This is fantastic battery life, and long battery life like this is exactly what I’m looking for on a red dot optic. 

I’ve had red dot batteries die on me in the middle of trips to the range before, and it gets pretty annoying…

But more importantly, you don’t want your red dot to stop working if you even need to use it in an emergency situation…

And when you have ultra long battery life like this, as long as you swap out your battery once a year, you’ll really never have to worry about it.

Now in terms of brightness settings, with the MRO you get 5 daylight settings, 2 night vision settings, and 1 extra bright setting…

The daylight brightness settings get very bright, and you’ll probably never have to use the extra bright setting even on a sunny day…

Also, even though most people will never use the 2 night vision settings, some people with NV equipment will take advantage of them, and I like that Trijicon includes them at no additional cost.   

Sig Romeo 5

The Sig Romeo 5 also uses 1 CR2032 battery which powers the sight for 50,000 hours (5 years)…

Again, I love ultra long battery life like this on red dot sights because you don’t want your optic’s battery dying on you at the wrong time…

In addition to that long battery life, Sig includes some they call the MOTAC (Motion Activated Illumination) system…

Basically, this means that your Romeo 5 will automatically turn off after 120 seconds of non use, and automatically turn on as soon as the sight senses any motion at all (like when you pick up your gun)…

This saves your battery life (which is already very long), and at the same time it keeps your sight ready to go as soon as you grab your gun.

I think it’s a really cool feature, and I’m glad that Sig includes it on this budget-minded red dot. 

Now with the Romeo 5 you get 8 daylight brightness settings and 2 night vision settings. Again, the daylight brightness settings get very bright and you shouldn’t have any problems with your reticle washing out even on a sunny day…

And just as with the MRO, I like that Sig includes the NV brightness settings without charging you extra money to get them (like some other optics companies do).  

Battery Life and Brightness Settings Conclusions…

So in this category both sights have great battery life, which is super important to me. In this day and age, I won’t even consider a red dot unless it has thousands of hours of battery life…

But in addition to that, they both have great brightness settings and included night vision settings. 

The one thing that really sets them apart is the MOTAC system included on the Romeo 5. The sight automatically turns off and automatically turns on when it senses motion…

This saves you battery life and keeps your sight ready to go at the same time. So because of the MOTAC system, the Sig Romeo 5 gets the slight win in this category.

Winner: Sig Romeo 5

Size Comparison…

Trijicon MRO

Like I mentioned earlier, the MRO is Trijicon’s version of a micro red dot sight. It only weighs 4.1 ounces, which is pretty lightweight…

And that’s an important feature for me because I’m always trying to keep the weight down on my rifles…

In addition to that, the MRO has a 25mm objective lens. This is a great thing for your field of view, but it does make the sight a little less compact than many of its competitors…

And last, the MRO is 2.6 inches long and 2 inches high… So again, it’s a pretty compact red dot sight. 

Sig Romeo 5

The Sig Romeo 5 is more of a traditional micro red dot sight than the Trijicon MRO. It weighs 5.1 ounces, which is a little heavier than the MRO but not by much…

The objective lens on the Romeo5 is only 20mm, which is more in line with other micro red dot sights, and it’s 1.52 inches high and 2.47 inches long…

All in all, I think the Romeo 5 is also a very compact sight.   

Size Comparison Conclusions…

Both of these optics are micro red dot sights, but they do have a few differences in this category… 

The Trijicon MRO is slightly more lightweight, which is impressive because it is slightly larger than the Romeo 5 in it’s dimensions…

That being said, The MRO is only around an ounce lighter, and the Romeo 5 is shorter in terms of length and height… 

So overall, the Romeo 5 is a slightly more compact sight, and I’m going to give it the win in this category.   

Winner: Sig Romeo 5

Extra Accessories Included With The Optic…

Trijicon MRO

The Trijicon MRO can be purchased with a low mount, a lower ⅓ co witness mount, an absolute cowitness mount, or with no mount…

The overall price of the sight will go up if you choose to get an included mount, which is a little bit of a disappointment for me…

But if you choose to get the MRO with one of the factory mounts (rather than with no mount), the good news is that they are high quality…

In addition to that, because the MRO is such a popular sight, there are a ton of aftermarket companies that make QD (Quick Detach) mounts, lightweight mounts, and any other type of mount you can think of.

So finding the right mount for you shouldn’t be much of a problem, but it will cost you extra money.   

Sig Romeo 5

The Sig Romeo 5 comes with some pretty cool accessories. First of all, you get a bikini lens cover, which will give your sight a little bit of extra protection…

But you also get 2 mounts included in the box, a high mount and a low mount. The high mount is perfect for use on an AR-15, and sets you up for an absolute co witness with back up iron sights…

And the low mount makes the Romeo 5 a great option for an AK, a shotgun, or any other firearm that favors a low mounted optic…

All in all, I love that the Romeo 5 comes with a low AND a high mount because it means you won’t have to spend extra money and you can start using your sight as soon as you get it.  

Extra Accessories Conclusions…

The Trijicon MRO doesn’t really come with any accessories, unless you pay more money to get an included factory mount…

On the other hand, the Romeo 5 comes with a lens cover that gives you optic a little bit of extra protection…

And with a low and high mount, which allows you to start using your optic without spending extra money (no matter what type of firearm you have). 

So for me, the clear winner in this category is the Sig Romeo 5.  

Winner: Sig Romeo 5

Price Comparison…

Unfortunately I won’t be able to give exact numbers in this category because the prices of these sights are changing all the time…

That being said, in general, you’ll find the Sig Romeo 5 for around 300 bucks less than the Trijicon MRO…

That’s a pretty significant chunk of change, so the clear winner in this category is the Sig Romeo5. 

Winner: Sig Romeo 5

Trijicon MRO Vs Sig Romeo 5 – Final Thoughts…

So to sum it all up, in the Durability And Toughness category, I gave the win to the Trijicon MRO because it is slightly more durable than the Sig Romeo 5…

In the Lens Clarity And Reticle Category, I called it a draw because both sights have some positives and negatives, and they both have the same reticle…

In the Battery Life And Brightness category, the Romeo 5 took the lead because of the auto off/auto on (MOTAC) feature…

In the Size Comparison, I also gave the win to the Romeo 5 because it is slightly more compact sight…

In the Extra Accessories category, once again the Romeo 5 came out on top because it comes with a low mount, a high mount, and a bikini cover…

And last, in the Price Comparison, the Romeo 5 was, again, the winner being around 300 bucks less expensive than the MRO…

So which of these sights do I prefer? I prefer the Sig Romeo 5…

I prefer the Sig Romeo 5 because it comes with a low AND a high mount, so you can start using it without spending any extra money…

It also has great battery life and the MOTAC system, which will save your battery life while at the same time keeping your sight ready to go…

In addition to that, the Romeo 5 is a very durable optic, and it has a crystal clear lens… And last, it’s around 300 bucks less expensive than the MRO, but it still maintains a very high quality level.

Now if you want a little bit more durability and you don’t mind spending more money to get it, then feel free to go with the Trijicon MRO because it’s still a great sight…

Either way, I hope I was able to show you the major similarities and differences between these two awesome red dot sights!

Holosun is one of my favorite optics companies…

I really like the cool features they put on their sights, and I love that they focus on keeping their optics affordable…

Right now, two of their most popular options are…

• The Holosun 510c (See Price On Amazon – Over 350 Reviews)
• The Holosun 507c (See Price On Amazon – Over 920 Reviews)

And in this Holosun 510c Vs 507c comparison, we’re going to see how these two sights stack up against each other in the following categories…

• Durability And Toughness
• Lens Clarity And Reticle
• Size Comparison
• Battery Life And Brightness Settings
• Extra Accessories Included With The Optic
• Price Comparison

In the end, I’ll tell you which of these two sights I prefer, and you should have all the information you need to determine which one will work best for you…

Let’s get into the comparison!

Durability And Toughness…

Holosun 510c 

The Holosun 510c is a pretty durable red dot sight. To start off with, the sight housing is made from a high strength aluminum…

…and it has an anodized surface coating that helps protect the optic from the elements. There is also a tough titanium hood that goes over the lens of the sight and gives it extra protection.

In addition to that, the windage and elevation turrets are recessed into the sight housing and can be adjusted using a screwdriver or the rim of a cartridge… 

I really like this feature because it means your adjustment turrets can never be spun or snapped off accidentally… 

Also, the 510c is fog proof and waterproof in up to one meter of water. So you won’t have any problems using it in rainy, snowy, or wet conditions…

And it’s also shockproof, so it can easily handle the recoil from high-powered rifles, shotguns, and pistol caliber carbines. 

All in all, I think the Holosun 510c is a very robust and reliable optic.  

Holosun 507c 

The Holosun 507c is also a very durable optic. First of all, the sight housing is made from 7075 T6 Aluminum, and it also has an anodized surface coating that helps protect it from the elements…

Additionally, just like with the 510c, the windage and elevation turrets on the 507c are recessed into the sight housing, so they’re protected from accidentally getting bumped or snapped off.

Also just as with the 510c, the 507c is waterproof and fogproof, so you can use it without any issues in rainy, snowy, or wet conditions. 

And it’s also shockproof so it can easily handle the recoil from shotguns, high-powered rifles, pistol caliber carbines, or from being mounted on pistol slides (which is the most common use for miniature reflex sights like the 507c).

All is all, I think the Holosun 507c is also a very tough and reliable optic. 

Durability And Toughness Conclusions…

So in this category we have some major similarities between these two reflex sights from Holosun, but we also have a few differences…

They both have a tough aluminum sight housing, and they both have recessed windage and elevation turrets…

They’re also both waterproof, shockproof, and fog proof. On the other hand, a major difference is the titanium hood that protects the lens on the 510c, and in addition to that, the 510c is a much larger sight…

So for those reasons I’m going to give the win in this category to the Holosun 510c.

Winner: Holosun 510c 

Lens Clarity And Reticle…

Holosun 510c 

The lens clarity on the Holosun 510c is very good. The lens is very clear and you don’t really get any of the blueish or greenish tint that you’ll find on some other red dot sights…

Also, since it is a full sized open-style reflex sight, the sight window is HUGE. It’s much bigger than a lot of other red dot sights, which is good because it gives you a much larger field of view… 

This allows you to see more of your target AND what’s around it, and it just gives you a really clean sight picture through the optic. 

Now included in the 510c is the MRS (Multiple Reticle System). This basically means that you can switch between 3 reticles…

• A 2 MOA dot
• A 2 MOA dot with a 65 MOA ring around it (Circle Dot Reticle)
• A 65 MOA ring (with no dot in the center)

The 2 MOA (minute of angle) dot is great if you want a really simple reticle. I’ve always found 2 MOA dots on red dot sights to be pretty easy for your eye to pick up (so you can shoot faster)…

But they’re also fairly small which allows you to aim with a fair amount of precision at small targets in the distance.

However, the Circle Dot Reticle is my favorite reticle for a red dot optic. That large 65 MOA ring is super easy for your eye to pick up when you need to shoot fast at targets up close…

But you still have that same 2 MOA dot for precision when you need it. I’m a huge fan of it, and like I said, it’s my favorite reticle on this style of optic.

Last, you have a 65 MOA ring with no dot. This option really doesn’t appeal much to me because I don’t think it does anything better than the Circle Dot Reticle, but it’s there if you find a use for it.

Last, Holosun offers the 510c with either red reticle options or green reticle options. I’ve always preferred red on my sights and optics…

…but there are a lot of people who really like the green reticles, and I like that Holosun offers both versions.      

Holosun 507c 

The Holosun 507c has pretty good lens clarity. There is a slightly blue tint when looking through the optic…

But it’s not really distracting, and it’s much clearer than other miniature reflex sights on the market like the Trijicon RMR. 

Honestly, I would prefer it to be a little more clear, but the slight tint is pretty easy to ignore, and I’ve never found it to affect my shooting (you still get a very clean sight picture when looking through the sight).

Now, like the 510c, the 507c has the Multiple Reticle System, but because it’s a much smaller sight, it’s a little more scaled down. The 3 reticles included are…

• A 2 MOA dot
• A 2 MOA dot with a 32 MOA ring around it (Circle Dot Reticle)
• A 32 MOA ring (with no dot in the center)

Again, I think the 2 MOA dot is a great option, especially if you want to keep things really simple. But as I mentioned already, the Circle Dot is my favorite reticle option…

I also want to point out that having a circle dot reticle on a miniature reflex sight is extremely unique and it really sets this sight apart from its competitors (from other optics companies).

Last, Holosun also offers the 507c with red reticle options or with green reticles options. Like I said before I prefer red, but it’s nice that Holosun offers both for those who like green reticles.    

Lens Clarity And Reticle Conclusions…

So in this category we have a few significant differences between these sights. First of all, I love the reticles on both of these optics and they’re very similar (the circle dot is scaled down for the smaller 507c)

That being said, the 510c has a much clearer lens than the 507c in terms of blue tint. I don’t think it’s a huge factor, but I always prefer a clearer lens when I can get it. 

In addition to that, the sight window on the 510c is much larger than the sight window on the 507c…

That’s obvious because the 510c is a much larger optic than the 507c, but it really becomes a big factor in this category.

So with all of this in mind, I think the Holosun 510c is the clear winner in this category.  

Winner: Holosun 510c

Size Comparison…

Holosun 510c

The Holosun 510c is a full-sized open-style reflex sight. It weighs around 8.3 ounces, which is pretty good in terms of weight for this style of sight…

In addition to that, it sits 2.31 inches high, and it is 3.3 inches long. Again, I think it’s a fairly compact sight in general. 

Holosun 507c

The Holosun 507c is a miniature open-style reflex sight. It only weighs 1.5 ounces, which is super lightweight for a red dot sight…

In addition to that, it only sits 1.54 inches high, and it is 1.78 inches long. All in all, it’s an extremely compact optic.

Size Comparison Conclusions…

So the 510c weighs 8.3 ounces, which isn’t bad for a full-sized reflex sight, but it’s much heavier than the 1.5 ounces of the 507c…

In addition to that the 507c is shorter than the 510c and sits much lower. It’s clearly a much more compact optic. So in this category the win goes to the Holosun 507c.    

Winner: Holosun 507c

Battery Life And Brightness Settings…

Holosun 510c

The Holosun 510c uses 1 CR2032 battery which is able to power the sight for around 50,000 hours (5 years)…

For me, super long battery life like this is a must-have on all red dot sights I use. I’ve had batteries die on me at the range before, which is really annoying…

But more important than that is you don’t want your optic dying on you if you ever need to use it in an emergency. 

So with this optic, as long as you swap out the battery once a year, you’ll never have to worry about the battery dying on you…

In addition to the long battery life, Holosun includes the Shake Awake feature, which basically means your sight will automatically turn off after a period of non-use and automatically turn on as soon as the sight senses motion (like when you pick up your rifle).

This will help save your battery life (which is already very long), and at the same time it keeps your sight ready to go as soon as you grab your gun.

Another feature included by Holosun is the solar panel. This is a cool feature because it means you can run your sight without a battery as long as you have some sunlight to power it…

I really like the solar panel because it works really well, and helps save your battery life even more.

Now with the 510c you get 10 daylight brightness settings and 2 night vision settings. The 10 daylight settings get very bright and you shouldn’t have any problems with them washing out even on a sunny day…

Most people won’t use the night vision settings, but some people with NV equipment will take advantage of them, and I like that Holosun includes them at no additional cost. 

Holosun 507c 

Depending on the version of the Holosun 507c that you get (I prefer the V2), the sight will either use 1 CR2032 battery or 1 CR1632…

Both batteries will power the sight for 50,000 hours (5 years) which, again, is very long battery life, and something I’m always looking for on my optics. 

The 507c also has the Shake Awake feature some it will automatically turn off after not being used and automatically turn on as soon as the sight senses motion…

And it has a solar panel that will power the sight without using up the battery just like the 510c does.

In addition to that, the 507c also has 10 daylight brightness settings and 2 night vision settings. Again, the daylight settings get very bright and I like that the night vision settings are included at no additional charge.  

Battery Life And Brightness Settings Conclusions…

There are a lot of similarities between these 2 Holosun optics in this category. Both sights have 5 years worth of battery life which is awesome…

They also both have the Shake Awake feature and a solar panel, to help conserve your battery life.

Last, they both have 10 daylight brightness settings and 2 night vision settings. There’s really nothing that separates these two sights here, so in this category, I’m going to have to call it a draw.  

Winner: DRAW

Extra Accessories Included With The Optic…

Holosun 510c 

The Holosun 510c comes with some pretty cool accessories. You get a tool to replace your battery and an extra battery tray just in case the original one gets damaged…

But the real exciting thing included is the QD (Quick Detach) mount that’s attached to the sight’s housing…

I really like it because it means you won’t have to spend extra money on a mount just to start using your optic…

But you are a bit limited by it because it really is intended to be used on an AR-15 or other AR platform firearms. 

You see, with an AR, the included mount will set the 510c up for an absolute co witness with back up iron sights…

That sets the sight rather high, which will be less than ideal if you want to mount it on something like a shotgun or an AK (platforms in which a low mount is more ideal)…

That being said, most people are looking to put an optic on their AR-15, So if that’s the case for you, the included mount will work perfectly. 

Holosun 507c

Just like the 510c comes with a mount, the Holosun 507c also comes with a mount. However, there are two big differences between them.

First of all, the included mount with the 507c is a low mount rather than a high mount. This makes it more useful on firearms like shotguns and AKs…

But it means you’ll need to purchase a high mount if you want to use your 507c on an AR platform rifle or pistol. 

Now secondly, the low mount on the 507c is removable, which is important if you intend to use the optic on a pistol slide (my preferred use for it). 

The Holosun 507c footprint is exactly the same as the Trijicon RMR, and that’s important because the RMR footprint is probably the most popular footprint out there for a mini reflex sight. 

So really, it should be relatively easy to find a mounting solution no matter what type of firearm you want to mount your 507c on.   

Extra Accessories Conclusions…

It’s tough for me to compare these two optics in this category because they both come with a mount, but the mounts are very different. 

The 510c’s mount is attached to the sight housing. It’s also a QD mount which is very cool, and it’s a high mount, so you’re pretty much limited to using it on an AR -15 (or other AR platforms)…

On the other hand, the 507c’s mount is a low mount, and it’s detachable, so you can easily purchase a high mount if you want to mount it on an AR…

Basically, both sights offer you a mount, and they both have some limitations. So in this category, I’m going to call it a draw.   

Winner: DRAW

Price Comparison…

Unfortunately I won’t be able to give exact numbers in this category because the prices of these sights are changing all the time…

That being said, they are usually very close in price, and sometimes you’ll actually find that they are priced exactly the same… So in this category, I’m going to have to call it a draw. 

Winner: DRAW

Holosun 510c Vs 507c – Conclusions…

So to sum it all up, in the Durability And Toughness category, I gave the win to the Holosun 510c because it has the titanium hood and it’s a much larger sight…

In the Lens Clarity And Reticle category, I also gave the win to the Holosun 510c because it’s lens has less blue tint than the 507c and the sight window is much larger…

In the Size Comparison, the Holosun 507c was the clear winner because it’s a much more compact sight…

In the Battery Life And Brightness category, I had to call it a draw because these 2 sights both have amazing battery life, the shake awake feature, solar panels, and the same brightness settings…

In the Extra Accessories category, I also called it a draw because both sights come with a mount even though the mounts are very different…

And last, in the Price Comparison, I had to call it a draw again because these two sights are very similarly priced. 

So which of these sights do I prefer? I prefer the Holoson 510c (depending on the use)…

I prefer the Holosun 510c if you plan to put the sight on an AR-15 or another AR platform firearm… 

First of all, the sight window is HUGE on the 510c which gives you a great sight picture, and the lens is super clear…

It’s also very durable, and it comes with an included Quick Detach mount so you won’t have to spend extra money to start using your optic…

Last, I love the Circle Dot Reticle because it allows you to shoot very fast at targets up close and still be very precise at targets in the distance.

Now if you want a super compact optic, if you’re mounting the optic on a pistol slide (my preferred use for this style of optic), or if your gun requires a low mounted optic (like an AK or a shotgun)…

Then feel free to go with the 507c because it’s still a really great sight…

Either way, I hope I was able to show you the major similarities and differences between these two awesome sights from Holosun!

It’s no secret that I’m a Holosun fan boy…

I just love that they pack their sights with cool (and useful) features and that they focus on keeping their optics affordable…

Now two of their most popular models right now are:

• The Holosun 403 (See Price On Amazon – Over 150 Reviews)
• The Holosun 503 (See Price On Amazon – Over 45 Reviews)

And in this Holosun 403 Vs 503 comparison, we’re going to examine how these two sights are similar and then point out the major differences between them…

In the end, I’ll tell you which of the two I prefer (I own both), and you should have all the information you need to determine which of them will work best for you…

Let’s get started!

Holosun 403 Vs 503 – What Are The Similarities?

Durability And Toughness…

Both the Holosun 403 and 503 are built to be pretty tough sights. To start off with, the sight housing on both of these Holosun models is made from 6061 T6 Aluminum…

And they both have an anodized finish, which helps protect the sight from the elements. Now some versions of 403 and 503 have part of the sight housing extended up and around the windage and elevation turrets…

And other versions don’t have this extension around the turrets. Personally, I prefer the versions that have the extra protection around the turrets because it’s just a little bit more protection against them being snapped off accidentally…

In addition to that, both the Holosun 403 and 503 are fogproof and waterproof in up to 1 meter of water, so they can easily handle rainy, snowy, or wet conditions…

Both models are also shockproof and can easily handle the recoil from high-powered rifles, shotguns, and pistol caliber carbines. 

All in all, both of the Holosun models are extremely reliable and tough. 

Lens Clarity…

Both the Holosun 403 and 503 have very good lens clarity. In fact, the lens clarity on these holosun micro red dots is better than the clarity you get from a lot of other micro red dot sights (even some that are priced much higher)…

I don’t notice any annoying bluish or greenish tint when looking through either the 403 or the 503, and the reticle is extremely clear and crisp. 

All in all, the sight picture you get from both of these Holosun models is very clean and their lenses are crystal clear.  

Battery Life And Brightness…

The battery life on both the Holosun 403 and 503 is very good. First of all, the battery these sights use with either be a CR2032 or a CR1632 depending on which particular version you get…

Both of those batteries are relatively common now, and you won’t have too difficult of a time picking up some extra batteries with either one…

Also, regardless of the battery used, you’ll get 50,000 hours (5 years) of battery life with both of these Holosun models…

Super long battery life like this is a must-have for any red dot sight I use because you don’t want your sight dying on you at the wrong time…

I’ve had sights die on me at the range before, which is really annoying, but more importantly, you don’t want your optic dying on you if you ever need to use it in an emergency…

Now to help save your battery life, Holosun includes the “shake awake” feature on both of these models. That basically means that your sight will automatically turn off after a period of non-use…

…and automatically turn on as soon as the optic senses any motion at all (for example when you pick up your rifle).

I love this feature because like I said before it helps save your battery life (which is already very long), and I like that Holosun includes it on both the 403 and the 503 models. 

In addition to that, if you go with one of the “c” versions such as the 403c and the 503cu, Holosun includes a solar panel on top…

This is very cool because it means your sight will run even if your battery dies on you, as long as you have some sunlight to power everything up.

Now both the 403 and 503 come with 10 daylight brightness settings and 2 night vision settings. The daylight settings get very bright, and you shouldn’t have any problems with your reticle washing out on you, even on a sunny day…

Most people won’t use the 2 night vision settings, but some people with NV equipment will take advantage of them, and I like that Holosun includes them on both of these models.   

Extra Accessories Included With The Sight…

Both the Holosun 403 and 503 come with the same accessories… They both come with a battery, which is nice because it means you can start using your sight immediately, and they both come with a lens cloth…

In addition to that, they both come with a rubber bikini lens cover, which gives you a little bit more ruggedness and two mounts, a low mount and a high mount. 

The high mount is perfect for use on an AR-15 and it sets you up for an absolute cowitness with back up iron sights…

…and the low mount is great for use on something like an AK, a shotgun, and some pistol caliber carbines. 

I love that both of these Holosun models come with a low AND a high mount because it means you don’t have to spend extra money to use your optic, and you can use your sight on pretty much any firearms platform you want to.  

What Are The Differences Between The Holosun 403 and 503?

Reticle Options…

Holosun 403

The major difference between the Holosun 403 and the 503 is the reticle. With the 403 you get a 2 MOA (minute of angle) dot reticle…

I think a 2 MOA dot is a good reticle for a red dot sight. I like it because the dot is fairly easy for your eye to pick up quickly when you need to shoot fast…

…but it’s also small enough to give you some precision, when aiming at small targets in the distance. It’s a good balance, and I much prefer it over something like a 4 or 6 MOA dot reticle. 

Holosun also offers the HS403 with a red, green, or gold reticle depending on the version you choose. I personally like to use red on my sights and optics, but there are a lot of people out there who really like the green reticle.     

Holosun 503

The Holosun 503 comes with 2 reticles that you can switch between, a 2 MOA dot and the Holosun Circle Dot Reticle (2 MOA dot surrounded by a 65 MOA ring)…

The 2 MOA dot is exactly the same as the reticle you get with the Holosun 403, and again, I think it’s a good reticle for a red dot sight… but I really love the Circle Dot Reticle.

The reason why I like it so much is because the 65 MOA ring just draws in your eye extremely quickly and allows you to shoot very fast at large targets up close…

But at the same time, you still have that 2 MOA dot in the center to give precision for small targets in the distance. Like I said, I really like it and it’s my favorite style of reticle on a red dot optic.

Now, just as with the 403, the Holosun 503 is available with a red, green, or gold reticle depending on the version you get. 

Again, I like the color red for my reticles, but I’m glad that Holosun offers the other color options as well.   

Price Differences…

Unfortunately, I won’t be able to give exact numbers here because the prices of the sights are changing all the time. The prices are also different depending on the version you choose to go with…

All that being said, the most affordable option is usually going to be the Holosun 403b (no solar panel) which you can find for around 100 to 120 bucks less than the most expensive option, the Holosun 503cu (solar panel and protected windage and elevation turrets). 

The Holosun 403c (solar panel) is usually around 50 to 60 bucks less expensive than the Holosun 503cu.

Holosun 403 Vs 503 – Final Thoughts…

So to sum it all up, both of these sights are very durable and tough. They both have excellent lens clarity. They both have ultra long battery life and the shake awake feature. 

They both have versions with solar panels or without them. And they both come with the same accessories including a low and a high mount. 

The two models are different because of the reticle they use. Again, the Holosun 403 just has a 2 MOA dot reticle, and the Holosun 503 has the 2 MOA dot reticle and the Circle Dot Reticle…

And because of the extra reticle the 503 is priced a little bit higher than the 403.

So which of these sights do I prefer? I prefer the Holosun 503, specifically the HS503cu…

I prefer the Holosun 503 because I love the Circle Dot Reticle. Like I mentioned before, it’s my favorite reticle on a red dot sight…

I really like that the 65 MOA ring allows you to shoot very quickly, but you still have that small 2 MOA dot to aim with when you need precision.

Simply put, it’s fast and precise, and it just works really well for me.

Now if you want to save a few bucks and are happy with a 2 MOA dot (still a great reticle!), I recommend you go with the more affordable option, the Holosun 403c because it’s still a great sight…

Either way I hope I was able to show you the similarities and major differences between these two awesome red dots from Holosun!

I’ve said it before, but I’ll say it again… I love Holosun optics…

They just create super high quality red dots that are packed with features, and they focus on keeping the prices affordable…

Now two of their most popular options in the ‘mini open-style reflex sight’ category are…

• The Holosun 407c (Check Price On Amazon – Over 364 Reviews)
• The Holosun 507c (Check Price On Amazon – Over 1,670 Reviews)

And in this Holosun 407c vs 507c comparison, we’re going to first go over how these two sights are similar (or exactly the same), and then we’re going to get into what makes them very different. 

In the end, I’ll tell you which of these sights I prefer, and you should have all the information you need to decide which optic will work best for you…

Let’s jump into it!

Holosun 407c vs 507c – What Are The Similarities?

Durability And Toughness…

Both the Holosun 407c and the 507c are very durable red dot sights. First of all, the sight housing on both sights is made from machined 7075 T6 aluminum…

..and they both have an anodized surface treatment to help protect the optic from the elements. 

In addition to that, they are both waterproof in up to 1 meter of water. So you’re not going to have any issues using them in rainy, snowy, or wet conditions.

Last, both models are tough enough to handle the recoil from shotguns, high-powered rifles, pistol caliber carbines, and of course, pistol slides…

This is important because an optic mounted on a pistol slide has to be able to take a lot of abuse as the slide moves back and forward on every shot…

…and both the 407c and 507c were built for this purpose from the start. All in all, both of the Holosun models are (equally) very tough mini reflex sights.    

Lens Clarity…

Both the Holosun 407c and 507c have great lens clarity. There is a tiny bit of blueish tint on both model’s lenses…

…but it’s very subtle and much less noticeable than the blue tint you get on the Trijicon RMR. All that being said, both sights give you a very clean and useful sight picture. 

In addition to that, the sight window on both the 407c and 507c is pretty large, especially for a miniature open-style reflex sight. 

The sight window (on both optics) is larger than a lot of the competitive options out there, and it’s impressive that Holosun still maintains such a durable optic given the large size of the sight window.

In the end, both the 407c and the 507c have great lens clarity and the same large sight window.  

Battery Life And Brightness…

Another similarity between the 407c and 507c is that they both have outstanding battery life.  Both models are powered by one CR2032 battery and the battery can last between 50,000 to 100,000 hours. 

Ultra long battery life like this is something I’m always looking for on my red dot sights because you don’t want your optic dying on you at the wrong time… 

…and as long as you swap out your battery once a year, you’ll never have to worry about it going out on you when you need it.

In addition to that, both of these Holosun models include the “Shake Awake” feature.  This basically means that your optic will turn off after a period of non-use and automatically turn on once the sight senses any motion at all.

This is another great feature because it helps save your battery life (which is already pretty long), and it keeps your optic always ready to go at the same time. 

Also, the “c” designation on the 407c and 507c actually means that these models come with a solar panel on top. 

So even in the off chance that your battery does stop working, your optic will keep working as long as you have some sunlight to power it up.

Last, both the 407c and the 507c have 10 daylight brightness settings and 2 night vision settings. 

The daylight brightness settings get very bright and you shouldn’t have any problems with your reticle washing out even on a sunny day…

And even though most people won’t use the NV settings, some people with NV equipment will, and I think it’s nice that Holosun includes them at no additional cost.     

Extra Accessories Included With The Optic…

Both the 407c and the 507c come with a detachable low mount for a picatinny rail. This mount is very useful if you intend to mount your optic on a firearm that favors low mounts such as a shotgun or an ak…

…but if you intend to run your Holosun on an AR, you’re going to have to invest in a high mount. Luckily both of these Holosun models use the Trijicon RMR footprint…

…and since the RMR footprint is one of the most popular footprints out there, you shouldn’t have a problem easily finding a mount.

Now, if you intend to use either of these Holosuns as a pistol optic, you won’t be needing a mount…

…and the fact that they both have the RMR footprint means that you shouldn’t have a difficult time getting them mounted on your pistol slide (again, because the RMR footprint is so popular).   

What Are The Differences Between the Holosun 407c and 507c?

Reticles Options…

Holosun 407c

The major difference between the 407c and the 507c is the reticle. The reticle on the 407c is a simple 2 MOA (minute of angle) dot…

I think a 2 MOA dot is a good choice for this style of optic because it does a good job of balancing speed and precision…

It’s easy for your eye to pick up a 2 MOA dot quickly, but at the same time, it’s precise enough to allow you to aim easily at small targets or targets off in the distance.

In addition to that, you can get the 407c with a red 2 MOA dot reticle or with a green 2 MOA dot reticle. 

Personally, I prefer red on my sights and optics because I find that it draws in my eye very fast, but there are a lot of people who really like the green dot. 

Either way, I like that Holosun offers the 407c in either a red or a green option.  

Holosun 507c

With the 507c you get 3 reticle choices that you can cycle between…

• A 2 MOA dot
• A Circle Dot (2 MOA dot surrounded by a 32 MOA ring)
• A 32 MOA ring with NO 2 MOA dot

The 2 MOA dot is exactly the same as you get on the 407c, and again, I think it’s a good reticle for a red dot sight…

But the Circle Dot reticle is my favorite reticle on a red dot sight. The reason why I like it so much is because the 32 MOA ring draws your eye in very quickly, but you still have that 2 MOA dot in the center to give you precision. 

I really like it, and it’s a very unique feature in the world of miniature reflex sights. Last, you have the 32 MOA ring with no 2 MOA dot…

I personally don’t have much of a use for this reticle because I think the Circle Dot Reticle does the same thing but also gives you precision…

…but it’s there if you find it to be a useful option. Last, just like the 407c, you can get the 507c with either red reticle options or green reticle options. 

Reticle Conclusions…

So, when it comes to the reticle, I definitely think the 507c is superior to the 407c… With the 507c you get the same 2 MOA that the 407c has…

But you also get the Circle Dot reticle and the 32 MOA ring reticle. Even though the 2 MOA dot reticle is good…

…I think the Circle Dot reticle is better because it’s just a little bit quicker for your eye to pick up, but still just as precise with the 2 MOA dot in the center.  

Price Differences…

Unfortunately I won’t be able to give exact numbers in this category because the prices of these optics are changing all the time…

That being said, you can usually find the 407c for around 60 to 70 bucks less expensive than the 507c…

Holosun 407c vs 507c – Final Thoughts…

So to sum it all up, both the 407c and the 507c are durable mini reflex sights. They both have great lens clarity…

They both have ultra long battery life. They both have great brightness settings, and they both come with a low mount for a picatinny rail and have the Trijicon RMR footprint.

The differences are that the 507c has 3 reticle options for you to cycle through, whereas the 407c only has the 2 MOA dot…

In addition to that, the 507c is around 60 to 70 bucks more expensive than the 407c.

So which of these optics do I prefer? I prefer the Holosun 507c.

I prefer the 507c because it’s exactly the same as the 407c except it has 2 more reticle options. Like I said earlier, I really like the Circle Dot reticle because it’s very fast and very precise…

And even though it is more expensive than the 407c, it’s only by around 60 to 70 bucks (which isn’t too much of a difference in my mind).

Now if you do want to save a little bit of money, and you’re happy with just a 2 MOA dot reticle (still a great reticle), then feel free to go with the Holosun 407c because it’s still a great optic…

Either way, I hope I was able to show you the major similarities and differences between these 2 awesome reflex sights from Holosun!

Let’s be honest, Trijicon makes some pretty cool optics…

They’re a well known name and they have a well-deserved reputation for putting out quality sights. On top of that, I think it’s pretty cool that Trijicon makes sights for the U.S. military… 

Now two of they’re most popular options right now are:

• The Trijicon MRO (See Price On Amazon – Over 341 Reviews)
• The Trijicon RMR (See Price On Amazon – Over 968 Reviews)

And in this Trijicon MRO vs RMR comparison, we’re going to see how these two sights stack up against each other in the following categories…

• Toughness And Durability
• Lens Clarity And Reticle
• Battery Life And Brightness Settings
• Extra Accessories Included With The Sight
• Price Comparison

In the end, I’ll tell you which of these sights I prefer, and you should have all the information you need to determine which one will work best for you…

Let’s jump into it!

Durability, Toughness, and Size…

Trijicon MRO

Trijicon has built up a reputation over the years for producing very tough optics. For years, the U.S. military has used the Trijicon ACOG…

…and the same high standards of ruggedness and durability have been put into the MRO. Now, MRO actually stands for “Miniature Rifle Optic”, and it’s Trijicon’s version of a micro red dot sight.

Like I said earlier, it’s built to be very tough. The site housing is made from 7075-T6 aluminum, and it’s hard anodized to help protect the optic from the elements. 

In addition to that, the windage and elevation turrets are recessed into the site housing, which prevents them from being snapped off or spun accidentally. 

The MRO is also waterproof and can be submerged in up to 100 feet (3 meters) of water. So it can easily handle rainy, snowy, or wet conditions…

…and last, it’s shockproof and can easily handle recoil from high-powered rifles, shotguns, or pistol caliber carbines.

At a weight of 4.1 ounces, the Trijicon MRO is a compact and durable little red dot sight, and it has a track record of reliability that goes back for a few years now.   

Trijicon RMR

The RMR is also a very durable little optic. Just like the MRO it has the Trijicon name and reputation behind it…

…and it was built with toughness and reliability in mind. Now instead of being a micro red dot sight, the RMR is a miniature open-style reflex sight.

In fact, RMR actually stands for “Ruggedized Miniature Reflex Sight”, and as I mentioned before, it was built with toughness in mind. 

The sight housing of the RMR is made from a forged military-grade aluminum alloy, and just like the MRO the windage and elevation turrets are recessed into the sight housing, which protects them from being bumped or snapped off.  

In terms of handling recoil and shock, the RMR Type 1’s did have some problems when mounted on pistol slides with the reticle flickering on and off intermittently…

It was basically a battery connection issue, and Trijcon completely corrected that issue with the RMR Type 2, which can easily handle the recoil from shotguns, high-powered rifles, pistol caliber carbines, or being mounted on pistol slides.

In addition to that, the RMR is extremely compact and only weighs 1.17 ounces… So it has become a popular choice as a pistol optic or a very minimal carbine optic. 

My one major knock on it in terms of reliability would be that it is an open-style sight, which means mud or debris could get into the open area and possibly block the emitter projecting your reticle (so you would have no reticle)… 

That’s just the way open-style reflex sights work, but aside from that, I think the RMR is a pretty durable little optic. 

Durability, Toughness, And Size Conclusions…

Ok so in this category, we have the MRO which is basically a micro red dot sight, and the RMR which is an mini open-style reflex sight…

Both of these sights are from Trijicon, so they’re both built with high-quality materials and toughness in mind…

…But because of the nature of the open-style reflex design and the simple fact that the MRO is a larger and beefier sight, I’m going to give the win in this category to the MRO.

Winner: Trijicon MRO

Lens Clarity And Reticle…

Trijicon MRO

The lens clarity on the MRO is pretty good. You do notice a slight bluish tint when looking through the optic, and honestly, I would prefer if it were more clear…

…but it’s not too distracting and I don’t think it’s a deal breaker. Trijicon says they put that coating on their lenses to make them stronger and to give you greater contrast when looking through the optic…

There is some truth to that, and even though I would prefer it to be more clear, you’re still able to get a very clear and clean sight picture through the MRO. 

In addition to that, the MRO has a 25mm objective lens, which gives you a huge field of view. This is an awesome feature…

…and it really sets the MRO apart from other micro red dot sights because you’re simply able to see more of what’s downrange when looking through your sight. 

Now the reticle on the MRO is a simple 2 MOA (Minute Of Angle) dot. I’m a big fan of the 2 MOA dot reticle on my red dot sights because it captures your eye very quickly when taking aim…

…but at the same time, it’s small enough to give you a fair amount of precision when shooting at small targets in the distance. 

Basically, it’s simple, fast, and precise, and I’m glad Trijicon decided to go with a 2 MOA dot reticle rather than something larger like a 4 or 6 MOA dot.  

Trijicon RMR

The lens clarity on the RMR is also very good. Just as with the MRO, there is a noticeable bluish tint when looking through the sight…

But again, you still get a clean sight picture, and the lens is very strong and gives you great contrast.

Now you can get the RMR with either a 3.25 MOA dot reticle or a 6.5 MOA dot reticle. Personally, I prefer the 3.25 MOA dot because similar to the 2 MOA dot on the MRO…

…it gives you more precision, but is still quick and easy for your eye to pick up.    

Lens Clarity And Reticle Conclusions…

Ok so in this category we have some similarities and some major differences between these two sights. First of all, they both have a slight blue tint on their lenses…

Again, I would prefer they both be a bit more clear, but it’s not a deal breaker, and the blue tint is the same on both sights…

Now, I do prefer the 2 MOA dot reticle on the MRO over the 3.25 MOA dot on the RMR because it’s just a little bit more precise and just as fast and easy for your eye to pick up.

In addition to that, I love the 25mm objective lens on the MRO, which is obviously much larger than the lens on the RMR, because it gives you a huge field of view when you’re looking through the sight. 

So in the end, I’m going to give the win in this category to the MRO because of the more precise reticle and the much larger field of view.

Winner: Trijicon MRO

Battery Life And Brightness Settings…

Trijicon MRO

The Trijicon MRO uses 1 CR2032 battery which is able to power the sight for 5 years of continuous use (on daylight brightness setting 3)…

I love ultra long battery life like this on my red dot sights. I’ve had red dot batteries die on me in the middle of range trips and it gets pretty annoying…

…but the more important reason for have long battery life on your optic is that you can keep your sight turned on all the time so that it’s ready to go if there’s an emergency…

All you have to remember to do is swap out the battery once a year, and you can leave your sight turned on without having to worry about it dying on you. 

It keeps things simple, which I really like. Now with the MRO you get a total of 8 brightness settings… 5 daylight, 2 night vision, and 1 extra bright.

The daylight brightness settings get very bright, and you shouldn’t have any problems seeing them even on a sunny day. 

And if the conditions get really extreme, you have that extra bright setting as well. Most people won’t ever use the night vision settings…

…but some people with NV equipment will and I like that Trijicon includes them at no additional cost. 

Trijicon RMR

The RMR also uses 1 CR2032 battery which can power the sight for 4 years.  Even though that’s not quite as long as the MRO it’s still pretty impressive for battery life…

…and as I mentioned before, I like my red dot sights to have very long battery life because you can keep them turned on and ready to go all the time. 

Now the RMR has 8 daylight brightness settings, 2 night vision settings, and 1 extra bright setting. Just as with the MRO, the daylight brightness settings get very bright even on a sunny day and you still have that extra bright setting for very extreme conditions…

Again, even though most people won’t use them, I like that the 2 NV settings are included at no additional cost…

But in addition to all that, Trijicon includes an auto adjustment feature in the RMR. This feature allows the sight to adjust to whatever your lighting conditions are automatically…

I think this is a pretty cool feature, but if you’d rather control the brightness levels yourself, you can switch the optic over to manual mode pretty easily.  

Battery Life And Brightness Settings Conclusions…

Ok so in this category the MRO can run for 5 years on the same battery whereas the RMR can run for 4 years…

In terms of brightness settings I think they’re pretty on par with each other because they both have bright daylight settings, NV settings and an Extra bright setting…

And last, the RMR has the auto adjustment feature, which can be turned off if you prefer to manually control the brightness on your optic. 

This is a close one, but even though the RMR battery life is pretty good, the MRO’s battery life is better, and for me, that’s the most important feature in this category…

So I’m going to give the win here, again, to the MRO.

Winner: Trijicon MRO

Extra Accessories Included With The Optic…

Trijicon MRO 

So when you pick up an MRO you have quite a few options available. You can get the Trijicon MRO with no mount, with a factory low mount, with a lower ⅓ co witness mount, or with an absolute cowitness mount. 

The low mount will make the MRO pair nicely with a shotgun, an AK, many pistol caliber carbines, and any other firearms platforms that favor mounting your red dot low…

The lower ⅓ cowitness mount and the absolute cowitness mount are both for use with an AR-15 (or another AR platform carbine, pistol, or rifle)…

Personally, I prefer an absolute cowitness with my back up iron sights, but there are many shooters who like the lower ⅓ cowitness.

In addition to that, there are many companies making aftermarket mounts for the MRO. QD (Quick Detach) mounts, ultra light mounts, and super strong mounts are all readily available…

So if you have a mount in mind that you’d prefer over the factory mounts, I think it’s good that Trijicon gives you the option of getting the MRO with no mount for a slightly lower price… 

Trijicon RMR

Just as with the MRO, you can get the RMR with no mount, a low mount, a lower ⅓ cowitness mount or an absolute cowitness mount.

Again, the low mount will be useful if you plan on mounting the RMR on a shotgun or an AK, and the higher mounts are for use with an AR-15…

There are also many aftermarket mounts including QD mounts made for the RMR, so it shouldn’t be difficult for you to find a mounting solution no matter what type of firearm you have…

Last, if you intend to mount the RMR on a pistol slide, the RMR footprint is one of the most popular footprints out there. So again, it shouldn’t be difficult to get your optic mounted.  

Extra Accessories Conclusions…

Both the MRO and RMR can be purchased without mounts, with low mounts, and with high mounts. They’re also both very popular optics, so many companies have made aftermarket mounts for them…

I don’t see much that separates these two in this category, so I’m going to have to call this one a draw.

Winner: DRAW

Price Comparison…

Unfortunately, I won’t be able to give exact numbers in this category because the prices of these sights are changing all the time…

That being said, you’ll generally find that the MRO is around 50 to 70 bucks less expensive than the RMR. So the slight winner in this category is the Trijicon MRO.

Winner: Trijicon MRO

Trijicon MRO Vs RMR – Final Thoughts…

So to sum it all up, in the Durability and Toughness category, the MRO came out on top because it’s a larger and more robust design…

In the Lens Clarity and Reticle category, the MRO also came out on top because I prefer it’s slightly more precise 2 MOA dot reticle…

Next, in the Battery Life and Brightness Settings category, the MRO was once again the winner because it has a little bit longer battery life than the RMR…

After that, in the Extra Accessories category, I called it a draw because both sights can be purchased with a variety of mounts or no mount at all…

And last, in the Price Comparison, the MRO was the slight winner because it’s just a little bit less expensive than the RMR…

So which of these sights do I prefer? I prefer the MRO…

The MRO is an awesome optic for any tactical rifle, carbine, or shotgun… First of all it’s super tough and can handle any abuse you throw at it…

But it also has a great reticle which is fast and precise, and it’s battery life is extremely long so it’s not going to die on you. On top of all that, it’s a little less expensive than the RMR…

Now if you want a sight for your rifle, carbine, or shotgun that is super lightweight and compact OR if you want a pistol optic, then feel free to go with the RMR because it’s still a great sight…

Either way I hope this comparison was able to show you the major differences between these two awesome sights from Trijicon!
