The forged 7075 T6 Aluminum A3 Upper incorporates a Flat-Top Picatinny Rail to accept the shooter's preferred optic, while the Single Rail Gas Block is compatible with flip-up or fixed iron sights. The 3G1 uses a Rifle Length Gas System for smoother functioning and a softer recoil impulse, both desirable qualities in a competition rifle. The upper comes complete and ready to fire with a bolt carrier group, charging handle, dual sling swivel studs, forward assist, shell deflector and ejection port door.
