The Armalite M-15 Versatile Sporting Rifle is loaded with features. Kicking off this build are the 7075-T6 forged aluminum upper and lower receivers.

The barrel is threaded 1/2x28 with a knurled thread protector and a 1 in 8" twist. The MBA-1 lightweight precision stock is adjustable for both length-of-pull and comb height. An adjustable gas block also allows the rifle to be individually set for optimal performance. Rifle-length gas system. MIL-STD 1913 top-rail. Ships with a 20-round Magpul PMag.
