AR-16: Armalite’s Lost Battle Rifle

The AR-16 was developed in the late 1950s as a less manufacturing intensive option to the AR-10. It began with the AR-12, which was a prototype intended to use a stamped receiver with the Stoner DI gas system. When Armalite sold the AR-15 patents to Colt, they had to revise that design, and it became the AR-14, with a Tokarev type short stroke gas piston and a stamped receiver. Two of these rifles were originally made, both chambered for .308 with folding stocks and mostly stamped parts. They were offered for sale, but there were no buyers – by the time the AR16 was ready most countries who needed a new rifle had already chosen the FAL, H&K G3, M14, or other option. Instead, when Stoner left Armalite, Arthur Miller scaled the AR-16 down to 5.56mm, where it became the AR-18.
