M4 UTAW PRO 300 Blackout 16″ Complete Upper Assembly

The M4 UTAW PRO Upper is one our pride and joys. This upper assembly is all MADE IN THE USA. This assembly encompasses our motto “Lightweight, Accurate, and Durable”. This is a true do it all upper that will fit any mil-spec footprint AR lower.

The upper receiver is billet and constructed out of 7075-T6 aluminum and receives a Type III Hard Coat Anodize. The upper is then outfitted with a Radian Raptor charging handle and a Strike Industries polymer dust cover. The handguard is constructed out of 6061-T6 aluminum and is also Type III Hard Coat Anodized. The barrel installed in this upper assembly is constructed from a 4150 CMV cold hammer forging. The barrel is then phosphate coated, chrome lined, and equipped with a nickel boron barrel extension. As a result of using a nickel boron extension and the nickel boron U.S. Arms bolt carrier group, allows the shooter to experience extremely smooth cycling with even wear. The muzzle device is a 4 prong flash hider.

All of these parts are then precisely assembled in house to bring the customer a reliable upper that will only need internal maintenance once the barrel is shot out.
