The AR103GN’s are Armalite’s flagship competition rifles that are built to win. This upper is 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 with a wide variety of ammunition. Includes a bolt carrier group and charging handle.
Compatible with Armalite AR-10 A-Series lowers.
