M153GN18) is ArmaLite’s flagship competition rifle, built compact, light, and ultra-fast around an 18-inch free-floating stainless steel barrel with a 1:8-inch twist and a rifle-length gas system. ArmaLite tops the barrel with its own tunable muzzle brake and an adjustable gas block for optimal individual performance, wraps it in a 15-inch free-float 3-gun handguard with a low-profile, railed front sight base, and fits an MBA-1 lightweight precision stock adjustable for length of pull and comb height. The rifle runs a Timney single-stage trigger and a Raptor ambidextrous charging handle, finished in black hard-coat anodized, and ships with a 30-round magazine. Among AR-platform rifles in the AR rifles category, the M-15 Competition favors 3-gun and precision competitors who want ArmaLite’s top-tier build.
