MP5 Red Dot Sights – My Top 5 Optics For HK MP5s (And Clones!)…

mp5 optics

The MP5 is such an iconic and awesome little gun…

Even though it’s been around for decades, it’s still considered by many to be the king of submachine guns (and pistol caliber carbines)…

Lately, there have been a lot of companies producing high quality clones of the MP5, so many more people are becoming proud owners of a variation of this firearm…

And many are wondering about optics… They’re wondering… what’s the best optic for my MP5 and how do I mount it?

So in this article, we’re going to go over some of the best MP5 optics mounts, and I’ll give you my top 5 list of MP5 optics!

Let’s get started! 

What’s The Best MP5 Optic Mount?

Before we get into the top 5 list of optics, we need to discuss a few mounting options you have when it comes to your MP5, because like the AK, the MP5 is not the easiest platform for mounting optics…

In my opinion, the best option when it comes to MP5 mounts is to have a picatinny rail welded on top…

Now some of the MP5 clones coming out now already have this as a feature of the gun, but many will not, and if that’s the case for you, don’t worry because you have quite a few mount options to choose from.

(I recommend mounting your optic low!)

Here’s a list of some of the most popular MP5 Mounts: 

The Battle Steel MP5 Mount – This is a great mount if you intend to run a micro red dot sight on your MP5. It comes in 2 versions… 

One version is for the aimpoint micro footprint which makes it compatible with all the aimpoint micro red dots, all the holosun micro red dots, the Sig Romeo 5, and many other red dot sights that use the aimpoint micro footprint. 

With this mount you get an absolute co-witness with your iron sights. So it’s one of the lowest mounting options available for the MP5. The second version is compatible with the Trijicon MRO.

Now the MRO is a little bit bigger than most other micro red dot sights, so if you use it with this mount you get a lower ⅓ co witness with your iron sights. 

Either way, this mount is a great option (depending on the optic you choose) because it keeps your sight mounted low.

The B&T MP5 Mount – This is an MP5 mount with a picatinny rail on it. It’s very high quality, and because it gives you a picatinny rail on top, you can pretty much mount any optic you choose.

The MFI MP5 Mount – This is also an MP5 mount with a picatinny rail on it. Again, it’s a high quality option, and you’ll be able to mount practically any optic you choose. 

The Kley-Zion MP5 Mount – This is another great low profile MP5 mount. It can also give you an absolute co witness if you’re running a micro red dot sight…

…but instead of attaching directly to the sight like the Battle Steel mount, your optic is mounted in a single picatinny rail slot with a low mount.

So unlike with the Battle Steel mount, you won’t have to use an optic with an aimpoint micro footprint.

There are many other great options out there as well, but if you need a solid MP5 mount, these 4 options are enough to get you started on your search. 

MP5 Red Dot Sights – My Top 5 List…

1. Holosun 503CU (My Top Pick!)

best mp5 optic

The Holosun 503CU is my number 1 choice for the best MP5 optic. If you’ve followed me for a long time, you know that I’m a huge fan of Holosun optics

I love the high quality level of their sights and the fact that they’re pretty affordable, and the 503CU is no different…

To start off with, the 503CU is a rugged little optic. The sight housing is made from a high quality aluminum, and it’s waterproof in up to 1 meter of water, so it can handle rainy conditions without any problems…

The lens on the 503CU is very clear without any of the greenish or bluish tint that you sometimes get on red dot sights, and you’re able to get a very clean sight picture. 

The battery on the 503CU will last for 50,000 hours (5 years), and it includes the Shake Awake feature, which means that your sight will automatically turn off after 10 minutes of non use and automatically turn on as soon as it senses motion. 

This is a feature I really like because it preserves your battery life, but at the same time your optic is ready to go as soon as you grab your firearm.

In addition to that, the 503CU gives you 2 reticle options to switch between. The first option is a simple 2 MOA (minute of angle) dot, which is a good reticle option for a red dot sight…

But the thing that really sets this sight apart from other red dot sights in its class is the second reticle option, the holosun circle dot. 

This is a 2 MOA dot surrounded but a 65 MOA ring, and I love it. The reason why is because the 65 MOA ring draws your eye in extremely fast and provides a huge aiming point for targets up close…

…but at the same time, you still have the precision of the 2 MOA dot in the center for small targets in the distance. It really is a fantastic reticle, and I think it’s a perfect match for a PCC (pistol caliber carbine) like an MP5. 

Now, you also get 10 daylight brightness settings and 2 night vision settings (if you’re using NV equipment) with the 503CU…

…and it comes with a bikini lens cover and 2 mounts, a high mount and a low mount. The high mount is for use with an AR-15, but the low mount will work great with any MP5 mount that gives you a picatinny rail on top…

And because the Holosun 503CU uses the Aimpoint Micro footprint, it can be mounted extremely low and co witness with your sights if you’re using a mount like the Battle Steel MP5 Mount. 

To sum it all up, the Holosun 503CU is a tough micro red dot sight with amazing battery life and an awesome circle dot reticle that’s perfect for an MP5!

2. Sig Romeo 5 (My Top Budget Pick!)

best red dot for mp5

The Sig Romeo 5 is second on my list, and in my opinion, it’s the best red dot for an MP5 (or any rifle honestly) if you’re on a budget…

To start off with, the Romeo 5 is an extremely tough little sight. It’s waterproof in up to one meter of water and fogproof, so it can easily handle rainy, snowy, or wet conditions…

…and the sight housing is made from Aircraft grade aluminum. The reticle on the Romeo 5 is a simple 2 MOA dot, which I think is a good choice because…

…your eye can quickly pick up the dot when you present your carbine and take aim, but at the same time, the dot is small enough to give you precision when shooting at small targets in the distance.

Like I said before, I do prefer the circle dot reticle that you get with the Holosun 503GU, but a 2 MOA dot is still more than adequate to get the job done. 

The lens on the Romeo 5 is super clear (no annoying greenish or bluish tint), and the battery will last you for 50,000 hours (5 years). 

In addition to the super long battery life, Sig includes the MOTAC system, which is an auto on/ auto off system.

It basically means that your Romeo 5 will automatically turn off after 120 seconds of non use, and automatically turn on if it senses any motion at all. 

This is a great feature because it saves your battery life but also keeps your optic ready to go, just in case you have to grab your MP5 in an emergency.

Also, the Romeo 5 has 8 daylight brightness settings to choose from and 2 NV settings (if you’re running NV equipment)…

…and last, it comes with a bikini lens cover and 2 mounts, a high mount and a low mount. Like I’ve mentioned before, the high mount is for use on an AR-15, but the low mount will work great with any MP5 mount that uses a picatinny rail on top…

And because the Sig Romeo 5 uses the Aimpoint Micro footprint, it can be mounted extremely low and co witness with your sights if you’re using a mount like the Battle Steel MP5 Mount. 

All in all, the Sig Romeo 5 is a very popular red dot sight because it’s tough, reliable, and it’s very affordable.

3. Holosun 507C

My number 3 pick for an MP5 optic is the Holosun 507c. I’ve already mentioned that I’m definitely a Holosun fan boy, but the 507C is very different from the 503GU that I mentioned earlier. 

The 507c is a tiny open-style reflex sight, and it’s perfect if you want an extremely compact and minimal optic for your MP5…

Even though it’s small, it’s still very tough and can easily handle the recoil and abuse from an MP5, and it’s packed with really cool features.

The lens is very clear (no annoying greenish or bluish tint), and its battery will last for 50,000 hours (5 years). 

It also has Holosun’s Shake Awake feature, so it will automatically turn off after 10 minutes of non use and automatically turn on as soon as it senses motion.

In addition to that, it has 3 reticle options that you can choose from, a 2 MOA dot, a 2 MOA dot surrounded by a 32 MOA ring, or a 32 MOA ring (with no dot in the center). 

Again, I’m a huge fan of the circle dot reticle, and I think it’s a perfect match for a PCC like an MP5, but the other 2 options are there if you prefer them. 

Last, the 507c comes with a low mount which means it will pair nicely with any MP5 mount that has a picatinny rail and it uses the Trijicon RMR footprint (so it will fit any RMR specific mounts). 

To conclude, the Holosun 507c is a super compact, tough little red dot sight, with awesome reticle options that will work great on an MP5!

4. Trijicon MRO

Number 4 on my list of optics for the MP5 is the Trijicon MRO. The MRO is super rugged and super reliable. It’s built like a tank. 

The sight housing on the MRO is made from forged 7075-T6 aluminum, and its waterproof in up to 100 feet (30 meters) of water.

It also has a huge 25MM objective lens, which gives you a large field of view when looking through the optic, and even though it does have a bluish tint on the lens, it’s not too distracting.

The battery will last for 5 years on setting number 3, and it has 5 daylight brightness settings, 2 NV settings, and 1 super bright setting (for extremely bright conditions).

The reticle on the MRO is a simple 2 MOA dot, which like a said earlier, is a good choice because it’s both fast and precise…

…and it comes with a low mount which will make it a good pair with any MP5 mount that gives you a picatinny rail.

And like I mentioned earlier Battle Steel actually makes an MP5 mount dedicated to the MRO, which mounts this optic very low and gives you a lower ⅓ co witness with the irons sights. 

All in all, the Trijicon MRO is a great choice if you want a super tough optic, a huge field of view, and a lower ⅓ co witness mount on your MP5.

5. Aimpoint T2

Number 5 on my list of optics for the MP5 is the Aimpoint Micro T2. Aimpoint, just like Trijicon, is known for making insanely tough optics, and the Micro T2 is tough, but at the same time, smaller than the Trijicon MRO.

The sight housing on the Micro T2 is made from a high- quality aluminum alloy, and it’s submersible in up to 15 feet of water. 

In addition to that, the lens on the Micro T-2 is very clear (no annoying green or bluish tint), and the reticle is a simple 2 MOA dot, which like I’ve mentioned before is a fast and precise option.

The battery on the Micro T2 will last for 5 years, and it has 8 daylight settings and 4 night vision settings. It also comes with a low mount, so it will pair nicely with any MP5 mount with a picatinny rail on top…

…and because it is an Aimpoint Micro, it will fit perfectly with the Battle Steel MP5 Mount, which will give you an absolute co witness with the iron sights on your gun

All in all, if you want aimpoint reliability, a very compact sight, and an absolute co witness with your iron sights, the Aimpoint Micro T2 is a great option.
