AR-10 vs. AR-15

In the 1950s, the Fairchild Aircraft company created a subdivision known as Armalite. This company designed lightweight, semi-automatic rifles. Since Armalite was relatively small, they focused on prototyping designs and selling them to larger manufacturers. Two of their most popular models are the AR-10 and the AR-15, which they sold to Colt in 1959. Although the AR-15 is the more well-known of the two, the AR-10 is also an excellent firearm to add to your collection.

Similarities Between the AR-10 and AR-15

One of the main similarities between these two rifle models is that they were designed to be incredibly lightweight. This is achieved by using lighter metals (such as aluminum alloy) and high-tech plastics.

Both models also use a direct impingement gas operation system. This means that gas from when a cartridge explodes is directed into the bolt carrier. As a result, the action cycles and a new cartridge can be placed into the chamber for firing. This allows the gun to operate without a separate gas cylinder, piston, or operating rod.

In general, the two styles of rifle look similar and have similar functionality. In fact, many parts are interchangeable between the two.


The AR-10 was a precursor to the AR-15, but this does not mean it is less advanced. AR-10 rifles have a longer barrel, weigh slightly more, and are larger as a whole. This is because they generally fire a larger caliber of cartridge. 7.62 NATO and .308 Winchester are common calibers for AR-10-style rifles. You may also see 6.5 Creedmoor and .260 Remington options.

AR-15-style rifles are among the most popular firearms in the United States. Many gun enthusiasts like to build and customize their own AR-15-style rifles. The main difference between this design and the AR-10 is that the AR-15 is smaller, lighter, and has a shorter barrel. It also uses different calibers, generally .223 Remington or 5.56 NATO.

Which Rifle is Best?

Choosing between an AR-10 and AR-15 often comes down to personal preference. You may want to try out both designs, as well as trying a few different models of each, to determine which one is best for you. Both are excellent guns and the quality often depends on the manufacturer.

In general, AR-15s have less recoil since they are slightly lighter. Many experts recommend AR-15-style rifles for home defense or small game hunting. Since the AR-10 uses a larger caliber, it is ideal to use as a big game hunting rifle.
