Why Go With The AR-10 In The First Place?

Let’s answer this question: why should you even go with an AR-10 to begin with?

The AR-10 is the larger cousin to the AR-15. It was first released in the late 1950s, and the AR-15 was actually developed from the AR-10 (many people assume it’s the other way around). Whereas the AR-15 is designed to fire intermediate rifle rounds and has a more compact and lightweight size, the AR-10 is heaver and larger in order to accommodate larger rifle rounds such as the .308 Winchester.

One reason to buy the AR-10 is because it’s so versatile. Even though it may be heavier and carry less ammunition than an AR-15, it packs a bigger punch and can tap targets at longer distances. An AR-10 can literally be used for anything from precision long distance shooting to self-defense to tactical training to big game hunting. Assuming you’re using a caliber like the .308 Winchester or 6.5 Creedmoor, an AR-10 can drop any kind of big game animal in North America.

Since the AR-10 is so versatile, a solid argument can be made that it (or a .308 semi-automatic rifle in general) is the one rifle to get if you can only have one. If you want a proven rifle that is accurate, reliable, ergonomic, and suitable for both tactical use and big game hunting, the AR-10 represents an excellent option on the marketplace today.

Another reason to get the AR-10 is because, along with the AR platform as a whole, it is one of the most customizable firearms in existence. It’s certainly more customizable than its main competitors like the Springfield M1A and the FN FAL. This means there are no shortage of upgrades you can make to your AR-10, and when building a new AR-10 from the ground up, you can actually have a tough time thinking about which specific components you want to use for it.

Since the AR-10 is customizable, there are a nearly limitless number of spare parts and accessories you can get for it. This includes a countless number of different stocks floating around on the market as well. When building a new AR-10 from the ground up, you’ll need to think carefully about the stock you want. If you are looking for more than just a stock, maybe consider an AR-10 build kit instead.

This is an important decision because the stock to your AR-10 has a significant impact in regard to how comfortable your rifle is to handle and shoot, and therefore on how skilled you can be with the weapon as well. Next, we’ll discuss the pros and cons to fixed and adjustable stocks, and then we’ll talk about the basic features to look for in any stock regardless of the basic type you choose.

Should You Go With A Fixed or Adjustable Stock?

There are two basic kinds of stocks for the AR platform: fixed stock and adjustable stocks. The first stocks like on the original AR-10 and the M16A1 were fixed, but adjustable stocks were later introduced. Today, you still have the option to choose between the two.

A fixed stock is exactly that: a fixed stock that cannot be adjusted. There are pros and cons to this system. On one hand, a fixed stock will not shift around while you are on the move as it’s a more solid design. This also means that, at least theoretically, it should be more dependable out in the field.

Many hunters in particular are accustomed to using a fixed stock rifle because traditional bolt action and lever action rifles use fixed stocks. This is why big game hunters who transition from a bolt gun to an AR-10 may be more comfortable using a fixed stock.

On the other hand, a fixed stock cannot be adjusted, so if the length of pull is not suitable for you then you’re out of luck.

An adjustable stock is exactly as the name suggests: the stock can be adjusted for length of pull, with there usually being four to six length options depending on your stock of choice.

Adjustable stocks are not as durable as fixed stocks and out in the field they may move around if not locked firmly into place. On the other hand, you can adjust them for length of pull, which you may appreciate. For storage purposes as well, shortening the stock shortens the overall length of the gun, which can come in handy. And if you find yourself needing to operate your AR-10 in tight conditions, shortening the stock length can also be a highly desirable feature to have.

Yet another type of stock would be a collapsible or folding stock, which literally fold up when not in use. However, folding stocks are not nearly as common as adjustable or fixed stocks for the AR-10. They also require a specialized adapter since you have to contend with the buffer tube, and in some cases, they may not even be legal depending on your jurisdiction.

As a result, a fixed or adjustable stock would be your best bet, and both are completely legal and don’t require any specialized tools or adapters to use. Both fixed stocks and adjustable stocks are also in wide use, and there’s no right or wrong choice. Ultimately, what you get should be based on your preference.

Buyer’s Guide For The Best AR-10 Stocks

These are the most important factors to consider when looking for a new stock for your AR-10:


This is by way and large the most important thing to look for in a stock because if your stock is not ergonomic, you simply won’t enjoy shooting your rifle. There are many factors that also go into determining how ergonomic your stock is for you: the length of pull, the shape, the texturing, and whether or not it can help to reduce recoil (such as if it has a rubber pad on the end).

At the end of the day, the only way to truly know if a stuck will be ergonomic for you is to get it and test it out. If you’re buying online, this means you’ll have to find one you think is good and then test it out.

Slip Free Surface

Remember that there are three main points of contact with a rifle: your firing arm, your shoulder, and your cheek. Each stock should come with a slip free surface so you can rest your cheek against it and press it against your shoulder without it slipping.

Little Drop

There should be little drop from the sights or scope of your gun to the stock, so you do not have to keep your head particularly high. Take note that this may become a problem if you add a scope to your gun, in which case it may or may not be necessary to add a cheek rise to the stock. The only way to know, again, is to test it out for yourself.


Most stocks for the AR-15 are made out of aluminum, fiberglass, or high grade composite polymer. Any one of these are a good option. While rare, it is possible to get wood stocks for AR-style rifles as well. However, wood stocks will swell more from moisture and are therefore not an ideal option.


Your stock should not add very much weight to your rifle. As a golden rule, plan on your AR-10 stock being a pound and a half or less.

Length of Pull

The length of pull is the distance between the trigger of your AR-10 and the end of the stock pressed against your shoulder. The length of pull of your stock should be comfortable for you based on your size and arm length. Again, experimenting with different options here is the key. This is also one reason why getting an adjustable stock for an AR-10 is nice so you can adjust it to your desired length.

Extra Storage Space

Last but not least, this isn’t truly necessary to have on an AR-10 stock, but it is nice to have: an extra storage space compartment. You can store things such as extra batteries for your red dot, a few rounds of extra ammunition, a small first aid kit, a flashlight, a small survival kit, and so on. You can actually get pretty creative with that you can stash away in there.
