Frequently Asked Questions

What is an AR-15?

The AR-15 is a highly customizable semi-automatic rifle. It was originally designed by ArmaLite in the 1950s to meet the US military's need for a standard-issue weapon that was lightweight, reliable, and modular. The military counterpart of the AR-15 (known as the M16) was the standard-issue rifle for the US Armed Forces from the late 60s to the early 2000s.

What are AR-15 pistols?

The AR-15 pistol is a modular handgun that uses the same receiver as a full-sized AR-15 rifle. Instead of being chambered for smaller calibers like 9mm rounds, AR-15 pistols are designed to shoot rifle rounds like .223 Remington and 5.56 NATO. You get a compact, maneuverable weapon without compromising on firepower.

Can I order an AR-15 for sale and have it delivered to my house?

No. All purchases on our site must be sent to an FFL dealer first and then picked up from the dealer. Before placing an order, you should contact your local licensed firearms dealer to confirm they can accept your purchased gun. If you don't, it's very likely they will return the package to us.
