Armalite's M153GN is the flagship competition rifle built to win. This rifle is compact, light, and ultra-fast. The low profile handguard, with a railed front sight base, covers a free-floating stainless steel barrel with ArmaLite's own tunable muzzle brake. An adjustable gas block also allows the rifle to be individually set for optimal performance. It has an MBA-1 lightweight precision stock (adjustable LOP/comb height), Timney single-stage trigger, and Raptor ambidextrous charging handle. This carbine model has a 13.5" barrel pinned and welded to muzzle brake to create a 16" barrel and a carbine-length gas system beneath a 12" free-float 3-gun handguard. It includes a 30-round magazine.
