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 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.
