Are you ready to own a gun that will be the envy of all your friends? Then, it's probably time to look into AR-15s.

Eugene Stoner designed the AR-15 at the request of the U.S. Army. It was initially intended for use on the battlefield, but today it's used for hunting, target shooting, and self-defense.

Learn more about this popular rifle below!

What Is an AR-15?

If any American-made rifle can claim to do it all, it's the AR-15. It's highly dependable, versatile, and accurate. These traits make it suitable for just about any use you could imagine.

An AR-15 is a lightweight semi-automatic rifle with a detachable magazine. It uses a gas system for cycling the bolt carrier group back and forth, chambering each round as it moves forward. This cycling allows the shooter to fire multiple rounds without reloading manually.

After its development by Eugene Stoner, ArmaLite sold the design to Colt. Colt then redesigned and modified it into the M16 for the U.S. military. It soon became the standard-issue automatic rifle for US soldiers during the Vietnam War.

Several iterations of this rifle have existed and are still used by the U.S. military.

What Does the AR in AR-15 Stand For?

Contrary to what the media would have you believe, the AR in AR15 does not stand for assault rifle, automatic rifle, or anything of that sort. Instead, AR refers to the original manufacturer,  ArmaLite (ArmaLite Rifle).

What Caliber is an AR-15

AR-15s are nominally chambered in .223/5.56mm NATO. However, manufacturers produce many variants in different calibers.

Here are some of the other calibers commonly seen:

  • .22-LR
  • 300 Blackout
  • 7.62x39mm
  • 6.5 Grendel

What Makes the AR-15 so Popular?

Ar-15s are hard to beat as an all-purpose rifle. They are affordable and easy to shoot, repair, and find parts for. It also lends itself nicely to building from the ground up.

The AR-15 is Great for Beginners

They are lightweight, have an excellent control layout, and typically feature adjustable stocks. Additionally, the price point is tough to beat!

The manual of arms are simple and easy to learn. The rifle has little recoil and minimal blast with most loads, making it accurate and effective for several hundred yards.

The tightly sealing action helps keep out dust and ensures excellent reliability. The rifle itself quickly strips for cleaning, and in a pinch, a little oil through the ports in the bolt carrier will keep the gun running until you can clean it.

Can a Civilian Have a Full Auto AR-15?

Under federal law, fully automatic weapons are technically legal only if made before 1986, when Congress passed the Firearm Owners' Protection Act. So it's now illegal to manufacture new automatic weapons for civilian use.

A civilian can purchase a full-auto firearm if they obtain a tax stamp. However, this only permits them to own automatic guns manufactured before 1986.

Who Makes the Best AR?
