CMMG AR-15 A3 Flat-Top Upper Assembly 22 Long Rifle 1 in 16" Twist 20" Barrel Chrome Moly Matte with A2 Front Sight, Flash Hider
CMMG's Evolution Series of rimfire uppers feature many significant improvements over previous designs, enhancing functionality, reliability, and ease of use. Prominent among these improvements are an Anti-Jam Charging Handle, Live Round Extraction ability, and Polymer Gas Deflector. CMMG's durable Weapons Armament Surface Protection (WASP) Melonite treatment has been applied to the barrel and surface-hardens the steel, extending barrel service life by reducing friction in the bore and lessening bore surface wear.
