Benefits of Adding a Few AR-10 Upgrades

As mentioned above, stock or factory accessories that come along with your AR-10 rifle are not the best choice and often do not cut the mustard, especially if you are looking at the assistance for precision shooting. Such accessories are easily susceptible to wear and tear and may not last as long as you want them to.

It is always a better decision to opt for upgraded accessories with enhanced longevity so that you can enjoy your AR-10 without worrying about needing to upgrade the parts frequently. Aside from better durability, here are a few more advantages that rifle owners can enjoy when they choose to upgrade their AR-10 accessories:

Better Reliability

Reliability should be an aspect that every gun owner should hold to a high standard. It doesn’t matter whether if you own an AR-10, AR-15, 1911 pistol, or a Mossberg 500 shotgun, you should always want the best reliability from your firearm to ensure they work when you need it most.

An example of increased reliability is when you upgrade your firearm magazine that will feed your shots into the chamber without jamming up. Another accessory to consider is a good trigger that will give you a light, crisp trigger pull for quicker shots that will ensure a better and more reliable AR-10 rifle.

Better Accuracy

Other than that, accuracy is also another aspect that AR-10 shooters hold to a high standard. It is undeniable that hitting your targets precisely where you want them to go is an impressive feat, no matter how far the target is.

Accuracy is critical when you plan to land a kill shot and drop a big game target in one go when you’re out in the field. Whereas, consistently hitting the bullseye will also ensure you get the best chance of winning the contest in competitive shooting.

To get the best possible accuracy out of your AR-10 rifle, you may want to consider getting a high-quality barrel. Other accessories are also bound to help improve your rifle’s accuracy, especially those designed to help you reduce recoil. Such accessories that have the ability to aid in felt recoil reduction includes buttstocks, muzzle brakes, and even forends.

Obviously, a good old-fashioned optic or scope will definitely help you get a more accurate and precise shot although it does not help much with recoil. All in all, the more necessary accessories you have, the better your firearm’s overall precision is.

More Customization

Some AR-10 accessories you upgrade with may even offer you the ability for more customization options. For example, an AR-10 handguard may come with a Picatinny rail to let you fully customize your rifle according to your preference.

The most popular choice of accessories that rifle owners love to attach onto their rail is either scopes or optics. These accessories are often very easy to install as they are designed to be compatible with the rail itself.

So, if you’re into customizing your own AR-10 rifle into a beast, then finding the right accessories that allow for better customization will be preferable.

The Popular Accessories to Consider


As discussed above, one major reason why a great barrel is one of the most important accessories for your rifle is that it delivers better accuracy. An A.R 10 barrel with a good twist rate ratio that accommodates your rounds will determine how accurate your AR-10 rifle is going to be. These accessories will also come in different lengths and gas systems.

Picking out the best barrel will depend on your needs and personal preferences. Generally, the longer the barrel, the better is the accuracy and velocity. Your rifle’s gas system will also determine how long your barrel needs to be.


Other than barrels, scopes can also help make your shots more accurate and precise. However, it is important to find the right optic that will give you the opportunity to acquire your target in one shot, regardless of the light conditions.

At the same time, getting a high-quality scope will also improve the long-range ability of your rifle considerably since you can now achieve a better aim. With that in mind, let’s take a look at our top pick for the scope we believe might be best for your AR-10.


It is very important to have complete control over your rifle as this could lead to less recoil and better accuracy. A good quality grip will ensure you get a good hold over your rifle, even when it’s raining cats and dogs outside. This is also a good option for those whose hands tend to sweat a lot.

Muzzle Brakes

The next best accessory for your AR-10 rifle is a muzzle brake. Muzzle brakes are designed to help reduce recoil considerably to ensure shooters achieve better accuracy with every shot.

With the muzzle brake on, you can expect your shot groups to get tighter and may probably even be sub-MOA. At the same time, a muzzle brake will also work to reroute the gas from gas system which propels from firing off rounds in other directions instead of right in your face.


It is without a doubt an excellent buttstock makes for a worthy investment, especially for those looking for superior control over their rifle.

Most buttstocks on the market these days are constructed from a polymer, meaning they’re extra durable and are designed to take on a lot of heavy-duty recoils often produced with AR-style rifles.

Not only are these stocks impervious to all kinds of weather conditions, but they can also resist damage caused by oil or cleaning solvents.

Picatinny Rails

For those who enjoy customizing their rifle should know that the Picatinny rail is one of the most popular rails on the market. They are measured consistently between spaces and ridges to make it easier for you to install all kinds of accessories and components onto your rifle.

This type of rail is perfect for those who have additional scopes or optics as you can easily attach them onto your rifle with a Picatinny rail.


An AR-10 rifle is by no means lightweight and the idea of carrying it around all day long, especially during hunting does not sound like a fun idea. Not only does lugging the rifle around all day mean your hands are full most of the time, but it is also very uncomfortable. Some days you might just need to use your hands while you’re out in the field or on the range.

The best hands-free solution in carrying your AR-10 rifle is to install a sling that gives you the best fit and comfort all while you’re using your hands to work other equipment or to drag a large game target such as a deer or elk, back to your truck.

Best AR-10 Muzzle Brake

8. CMMG RKM15 Handguard

Best AR-10 Handguard


Dragging heavy firearms around to a deer stand, shooting bench or even a 3-gun match can often be a burden, especially considering the .308 AR is already a fairly heavy gun itself. Adding on the quad-rail handguard, bipod, and other accessories onto it and you’ll quickly find yourself having to deal with a 13-pound carbine. Fortunately companies these days build KeyMod or M-Lok handguards from aircraft-grade aluminum to offer modularity without being too bulky.

The CMMG RKM15 Handguard is one that I really like as the rail is in KeyMod format and is 15 inches in length. Built from 6061-T7 aluminum-grade aluminum, this .308 AR handguard weighs a scant 13 ounces only. It is also located so close to the rifle’s receiver such that the firearm’s balance won’t be affected. The RKM15 handguard also floats freely and features a proprietary barrel nut that comes with the rail kit.

The L7 AWM is Lancer’s latest addition and is available in 5, 10, 20, and 25-round variation. These new magazines are tough as nails and offer a variety of capacities to suit any shooter who wants to fire from any position.




The best accessories for your AR-10 is definitely out there in the world for you. Upgrading your weapon over factory stock parts is one of the smartest decisions you’ll ever make as you notice the improvement in overall performance once you’re able to put them to the test.

Likewise, if you’re building an AR-10 from the ground, then you should make sure to build it using nothing but the best parts available. Either way, your firearm should offer the best in terms of longevity and quality. Hopefully, today’s article has given you enough information and a review of the best upgrades you can get for your .308 AR firearm.
