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 13.5-in. barrel with Armalite’s own tunable muzzle brake that is pinned and welded to create an overall length of 16” – meaning this upper is not subject to NFA requirements! 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® B-Series lowers.
