Frequently Asked Questions

What is the Armalite AR-16?

The Armalite AR-16 is a rare 7.62 NATO battle rifle prototype developed by Armalite, serving as a bridge between the AR-10 and the AR-18. It featured a stamped sheet metal receiver and a short-stroke gas piston system.

Why was the Armalite AR-16 developed?

The AR-16 was developed as a more cost-effective alternative to the AR-10, utilizing stamped sheet metal for its receiver and a gas piston operating system due to Armalite's licensing of the AR-15 rights. It aimed to test manufacturing techniques for future designs like the AR-18.

What operating system does the Armalite AR-16 use?

The Armalite AR-16 employs a Tokarev-style short-stroke gas piston system. This was a departure from Eugene Stoner's direct impingement system, which Armalite had sold the rights to Colt for the AR-15.

What is the legacy of the Armalite AR-16?

Although never mass-produced, the AR-16's innovative design, particularly its stamped receiver and piston system, significantly influenced the development of subsequent combat rifles, including the AR-18 and later firearms like the L85, Steyr AUG, and G36.
