The CMMG AR-15 M4 LE .22 Long Rifle A3 Upper is a complete, dedicated rimfire AR-15 conversion upper that maintains compatibility with most of the same parts and accessories employed on centerfire caliber AR's. The customizable Revolution Handguard has a continuous top rail and provisions for mounting rail sections to attach accessories, while also free floating the barrel for greater accuracy potential. The 22 Long Rifle conversion bolt, along with the barrel's true 22 LR chamber and proper 1/16" twist rate, make for a truly accurate rimfire AR-15 for inexpensive practice, small game hunting, and introducing young or new shooters to the AR-15 platform.

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.
