smith and wesson m&p 15 sport 2 upgrades

If you’ve recently picked up a Smith And Wesson M&P 15 Sport 2, then Congratulations! You’ve picked up an awesome AR 15!

The M&P 15 Sport is an amazing AR because it’s an affordable option that doesn’t really sacrifice on quality…

But are there parts on this incredible rifle that can be upgraded or improved? Is The M&P Sport 2 Customizable? The answer is… absolutely!

And that’s exactly why I’ve created this Smith And Wesson M&P 15 Sport 2 Upgrades list…

In it, you’re going to see what I think are some of the best accessories for your M&P 15 Sport 2…

And by the end, you’ll be able to decide which areas you should upgrade on your Sport II and which areas you should keep stock from the factory (just as they came)…

Let’s get started!

Smith And Wesson M&P 15 Sport 2 Upgrades – Top 14 List…

1. Midwest Industries AR-15/M16 M-Series Two Piece Drop-In M-LOK Handguard 

smith and wesson m&p 15 sport 2 handguard

Like I said earlier, the M&P 15 Sport is a fantastic rifle, but there is one part that I consider to be absolute junk…and that is the cheap plastic handguard…

Now don’t get me wrong, I think the M&P 15 Sport 2 handguard looks nice, but it’s junk because it’s just a thin piece of plastic. It doesn’t have any heat lining in it, and I’ve seen one (the stock handguard) start to melt after firing just a couple of mags through the gun…

Here’s the good news… I think this is a great place for Smith & Wesson to save you some money (on the overall price you paid for the gun) because changing out your handguard is one of the easiest things you can do on your AR…

So the first upgrade I recommend for your M&P 15 Sport 2 is to replace the cheap plastic handguard with something better, and my favorite option right now is the Midwest Industries Drop In M-LOK Handguard. This is an amazing handguard for a few reasons…

First of all, it’s made from a high-quality aluminum. So it’s going to be a durable addition to your AR, but in addition to that, the M-LOK is also going to allow you to mount any other accessories that you might want (such as lights, lasers, vertical grips, bipods, etc.) onto your handguard

It’s also super easy to install, and aside from adding a lot of function to your rifle, it looks really freaking cool.

2. MAGPUL MOE SL CARBINE STOCK (MIL-SPEC)

m&p 15 sport 2 stock upgrade

Another great place to upgrade your M&P 15 Sport 2 is in the collapsible stock. Again, the stock that comes from the factory is just cheap plastic, and I have seen this type of AR stock break many times before…

It also limits you on the ways you can attach a sling to your rifle, and it rattles around quite a bit, which isn’t a functional problem but some people find it to be pretty annoying…

So right now, my favorite stock upgrade is the Magpul MOE SL Carbine Stock. I love this stock for many reasons. First of all, it fits very securely onto the buffer tube of your rifle. It’s still easy to adjust the length of pull, but it doesn’t have any of the annoying rattling that you get with the factory M&P 15 Sport stock…

In addition to that, it’s a very strong stock, and it does offer you a few different ways of attaching a sling to your rifle. It’s also extremely comfortable in your shoulder, and I think it looks awesome. In fact, I love the variety of colors that Magpul always seems to offer on all of their AR accessories. Important Note: The M&P Sport comes with a Mil-Spec sized buffer tube. So make sure that the stock you get is “mil-spec” rather than “commercial” in size.

3. Magpul MOE K2 + Grip

best accessories for m&p sport 2

Another part that I think you should seriously consider upgrading on your M&P 15 Sport is the grip. Most models of the Sport come with an A2 style pistol grip, and frankly, I think the A2 pistol grip sucks…

There are two reasons why I, personally, do not like the A2 pistol grip. The first reason is because it has a finger ledge. I can’t stand the A2 grip’s finger ledge because every time I try to grip one, my middle finger sits right on top of it. I then have to lower my hand on the grip and then start shooting, which is incredibly annoying…

The second reason why I don’t like the A2 grip is because it’s pretty skinny and doesn’t really fill my hand well. This is less of a problem than the finger ledge for me, but it’s still not ideal. So I always end up changing A2 style grips on my AR’s, and right now, my favorite aftermarket grip is the MOE K2+ Grip…

First of all, the MOE K2+ has no finger ledge. So I can grab it comfortably every time without adjusting my hand. In addition to that, it fills my hand the perfect amount without feeling too skinny. Also, because it’s the K2 version of the MOE, it sits at a slightly more vertical angle than the A2 grip, which I find to be a bit more comfortable when shooting. And last, it’s also the + model, which means it has a rubber coating around it that makes the grip feel amazing…

And don’t forget that Magpul makes their grips in a number of really cool colors, so you can either pick up a black grip to keep your rifle more unassuming, or get a grip with color to add a little more personality to your M&P 15 Sport.

4. INFORCE WML Gen 2 Weapon Mounted White LED Tactical Light

best accessories for s&w m&p 15 sport

One of the best accessories for your S&W M&P 15 Sport is the addition of a weapon light. This can easily be done if you’ve already upgraded the stock handguard, but even if you don’t want to upgrade the Sport’s handguard, there are light mounts that can attach to the front sight post and other areas as well…

A weapon light is extremely important if you think there’s ever a chance that you could use your rifle in self-defense, and I automatically put a light on all of my AR 15s. That being said, one of the coolest weapons light you can get is the Inforce WML…

The Inforce WML is a fantastic light because it has 400 lumens, which is plenty of power to light up targets at close or mid-range distances. It also comes with an integrated mount, so you can put it on your M&P Sport without buying an extra part (a light mount), and the angled button is simple and very easy to use. Aside from all of that, it’s a very rugged light, and it looks awesome.

5. CMMG .22 LR CONVERSION KIT BRAVO WITH 3-10 ROUND MAGAZINES

m&p 15 sport 2 upgrade kit

These days, the cost of shooting .223/5.56 ammo out of your M&P 15 Sport 2 can really add up. But what if there was a way that you could shoot your Sport a lot more without having to break the bank on expensive ammo bills. Well, there actually is and it’s called the CMMG .22 LR Conversion Kit…

This is an amazing M&P 15 Sport 2 Upgrade kit! Basically, all you have to do is replace your BCG (Bolt Carrier Group) with the .22 LR Conversion Kit and change out your magazines, and in a few seconds, you can switch calibers on your Sport from .223/5.56 to .22 LR (much cheaper)…

I love it because it’s a reliable conversion kit, and again, it allows you to save quite a bit of money by shooting much less expensive .22 LR out of your Sport. You can use it as a training device that allows you to shoot your exact same rifle and optic set up at a much lower cost, or you can use it as a way to have fun at the range shooting boxes of cheap .22 LR. It really is an awesome upgrade and I recommend it to anyone who owns an AR 15.

6. CMC DROP-IN TRIGGER (SINGLE STAGE, TACTICAL FLAT BOW, 3.5LBS)

m&p 15 sport 2 optics ready upgrades

The M&P 15 Sport 2 has what’s generally referred to as a “Mil Spec” trigger. It’s a decent trigger, but there’s definitely room for improvement. And right now, my favorite trigger upgrade for the Sport II is the CMC Tactical Flat Bow Drop-In Trigger…

First of all, this trigger looks really cool, and because it’s a drop-in trigger, it’s easy to install. In addition to that (and I can’t really explain why) but the flat-faced trigger feels better to me than a standard curved trigger, and it just makes my shooting experience more enjoyable (maybe because I’m more accurate)…

This trigger also pulls at a clean 3.5LBs which makes it very easy for you to pull the trigger straight back without disturbing your sights (it’s easier to be accurate with it). And on top of all that, the CMC Drop-In trigger is pretty affordable, especially considering the prices of other aftermarket triggers that are in its class.

7. VG6 GAMMA 556 Muzzle Brake

VG6 GAMMA 556 Muzzle Brake

The muzzle device that comes standard on the M&P 15 Sport 2 is basically an A2 flash hider. It’s a good muzzle device if you want to hide the flash from your muzzle in low-light situations, but it’s definitely a basic muzzle device that can easily be upgraded…

One of the best options, if you want to upgrade this part of your rifle is the VG6 Gamma 556 Muzzle Brake. The reason why I like it is because it makes your rifle recoil less and stay extremely flat when you shoot. This allows you to make very quick and accurate follow-up shots, and it just helps you shoot faster because your rifle doesn’t push you back as much…

The one downside to the VG6 Gamma (and all muzzle brakes really) is that it can make your AR pretty loud. That being said, I think the benefits you get in shooting performance from the VG6 Gamma far outweigh the noise, and if the noise is a big problem for you, you can pair it with the VG6 Cage Device which will quiet down your rifle.

8. PSA CUSTOM AR 15 AMBIDEXTROUS CHARGING HANDLE

PSA CUSTOM AR15 AMBIDEXTROUS CHARGING HANDLE

For me, there are two main problems with the standard GI-style charging handle, which is what comes on the M&P 15 Sport. First, it’s small and extremely hard to pull back with just your left hand if you’re right-handed (my hand slips off almost every time)…

Second, it’s not ambidextrous (a huge problem if you’re left-handed). Because of that, I like medium/big latches on my charging handles, and even though I am right-handed, I like ambi charging handles just because they give you options…

Now you can end up spending a lot of money on a charging handle if you’re not careful, but one of the best ‘bang for your buck’ charging handles you can get to upgrade your M&P 15 Sport is the PSA Custom AR 15 Ambidextrous Charging Handle…

I love this charging handle because it has large (but not too large) latches that make it easy to manipulate your gun. It’s also ambi, which again, gives you more options (to reload, clear malfunctions, etc.) even if you’re right-handed. Last, it’s built to a high standard with quality materials. It’s a simple upgrade, but it’s one of the best accessories for your M&P Sport 2 because you’ll notice it every time you shoot your rifle.

9. Holosun 510C Red Dot Sight

Holosun 510c review

I think it’s a good idea to upgrade your M&P 15 Sport with an optic. There are many different types of optics that you can choose from, but if you choose to go with a red dot sight, I think the Holosun 510C is an amazing option…

Now the 510C is an awesome choice for several reasons. To start, it has a large viewing window which gives you a huge amount of visibility when you’re shooting. And I also love the multiple reticle system because it has a Circle Dot Reticle, which is my favorite on a red dot sight because it helps you shoot fast and accurately…

It’s also packed with useful features such as super-long battery life, a solar panel on top, and shake-awake technology, and because the 510C has a titanium hood protecting its lens, it’s a very rugged sight as well…

Last, it’s a Holosun. So that means you’re going to get a high-quality sight that’s set at a reasonable price. For all those reasons, I think the 510C makes a great pair with an M&P 15 Sport!

10. MAGPUL MBUS PRO LR ADJUSTABLE REAR SIGHT

MAGPUL MBUS PRO LR rear SIGHT

Magpul makes some fantastic flip-up sights. In fact, your M&P 15 Sport 2 might have come with a polymer Magpul rear sight when you purchased it. That polymer Magpul MBUS sight is very good, but like most other parts, it can be upgraded as well…

If you don’t have a rear sight on your Sport, or if you want to upgrade your rear sight, I highly recommend you take a look at the Magpul MBUS PRO LR Adjustable rear sight. Magpul is known for their polymer products, but this is actually a steel rear sight that they offer. And even though I think their polymer sights are very good, their steel sights are even better…

Being steel, this sight is obviously going to be more rugged and reliable than polymer Magpul sights. But at the same time, it’s also very low profile when flipped down. So it can easily fit under a scope or behind a red dot and be used at a BUIS (Back Up Iron Sight). Another feature I really love about the MBUS PRO LR is that it’s fully adjustable for windage and elevation without any tools…

That allows you to really dial in your iron sights, which is obviously important because you can be more accurate, but having that ability to precisely dial in your iron sights makes shooting with them a lot more fun (in my opinion). So all in all, the Magpul MBUS PRO LR Adjustable Rear sight is one of the best sights you can get if you want to upgrade your rear BUIS.

11. Bushnell AR Optics Rifle Scope 1-8x24mm

bushnell ar optics 1-8x24 riflescope

Like I mentioned before, it’s a good idea to put an optic on your M&P 15 Sport 2, and another great option is to go with an LPVO (low powered variable optic), which is a rifle scope that can be switched from 1x power to a higher magnification very quickly…

Now, scopes of this type can get extremely expensive, but one of the best options that balances affordability with performance is the Bushnell AR Optics 1-8x Rifle Scope. This is an awesome scope for any AR 15…

I like it because it has a very useful BDC (Bullet Drop Compensator) reticle which is designed to help you acquire a sight picture fast when the scope is on 1x power (much like you would with a red dot sight) and at the same time, do hold-overs when you’re shooting at different far off distances…

I also like that the glass is pretty clear, especially considering the cost of the scope, and I love that you get a throw lever included because it allows you to switch from high to low power (and back) on your scope very easily and very quickly. So all in all, the Bushnell AR Optics 1-8x is a great scope, and it would go well with any AR 15 including the M&P Sport. (Bonus – add this magnifier to it for double the magnification!)

12. PSA CUSTOM 5.56 BCG (DLC COATED, DARK EARTH)

PSA CUSTOM 5.56 BCG DLC COATED- DARK EARTH

The BCG (Bolt Carrier Group) that comes in the M&P 15 Sport is very good. It’s not a part that needs to be upgraded, but if you do want to upgrade it, I think the PSA Custom 5.56 BCG is a great choice to go with…

I like the PSA Custom BCG because it’s made using very high quality materials and it’s built to a high standard. The DLC (Diamond Like Coated) finish is an upgrade over the standard finish that comes on the M&P 15 Sport’s BCG because it’s more rugged, and it also adds lubricity to the Bolt Carrier Group…

That extra lubricity makes your gun run smoother even with a minimal amount of oil, and it also makes your BCG very easy to clean because most of the time you can just wipe off the gunk with a dry rag…

The Dark Earth color also adds a little bit of flair and personality to your Sport, and I do think it’s a good idea to have spare parts ready for your AR 15 because even quality parts can and do break. So if you do choose to upgrade your BCG, you can keep your stock BCG (and all its little parts) in reserve and ready to go if you ever need them.

13. Raven Ultra-Compact 3×32 Prism Scope

monstrum tactical raven review

Another really cool optic that not many people know about right now is the Raven Ultra-Compact 3×32 Prism Scope by Monstrum Tactical. It’s a fixed 3x scope, but it’s much more lightweight and more compact than an LPVO (low powered variable optic)…

It also has a Circle Dot Reticle which is etched and can be illuminated to be red or green with the optic’s batteries. And because the reticle is etched, you don’t even need to have a battery in the scope to have the reticle show up, which is not the case with a red dot sight…

I also like the Raven because the lens is pretty clear, it’s built like a tank, it’s affordable, and it comes with a mount, so you won’t have to buy an extra part to get it mounted on your gun. So I think it’s a really cool and unique optic that would look and perform great on your M&P 15 Sport.

14. Faxon Firearms AR-15 Pencil Profile Barrel

smith and wesson m&p 15 sport 2 barrel upgrade

The AR 15 is like a lego set for gun guys (and gals), and if you haven’t realized by now, there’s really no part that you can’t customize or upgrade. Even the barrel on your M&P 15 Sport can be swapped out for something a little bit better, and right now, a really cool option is the Faxon Firearms AR-15 Pencil Barrel…

Faxon is famous for making super high-quality barrels that are very accurate, and that have upgraded features like a 1-8 twist rate. On top of that, because it’s a pencil profile barrel, adding it on to your Sport will make the gun much lighter in terms of weight (especially weight toward the front of the gun which affects how the weapon handles)…

So again, if you do want to upgrade your M&P 15 Sport barrel and maybe keep the original as a back up, the Faxon Firearms Pencil Profile Barrel is a fantastic option that doesn’t break the bank.
