The M153GN's are Armalite's flagship competition rifles that are built to win. This carbine is compact, light, and ultra-fast. The low profile handguard covers a free-floating 18-in. barrel with Armalite's own tunable muzzle brake. An adjustable gas block also allows the rifle to be individually set for optimal performance.
