Product Information

This CMMG AR-15 Evolution M4 A3 Upper Receiver is a complete, dedicated rimfire AR-15 conversion upper chambered in 22 Long Rifle that maintains compatibility with most of the same parts and accessories used in centerfire caliber AR's. It comes equipped with a customizable, free floating Revolution handguard that provides a continuous top rail platform for optics or iron sights, as well as provisions for mounting additional modular rail sections along its length for the attachment of any desired tactical accessories. The 22 Long Rifle conversion bolt assembly, along with the barrel's true 22 LR chamber and proper 1 in 16" twist rate, make for an accurate, reliable AR-15 rimfire trainer for inexpensive practice, training, small game hunting, or for introducing young or new shooters to the AR-15 platform. This upper assembly is shipped complete and ready to fire out of the box upon installation onto any standard lower receiver (magazine sold separately).

CMMG's Evolution Series of rimfire uppers feature many significant improvements over previous generations to enhance their functionality, reliability, and ease of use. Prominent among these improvements are a polymer anti-jam charging handle, live round extraction ability, and the integration of a gas deflector. CMMG's extremely durable Weapons Armament Surface Protection (WASP) Melonite finish has been applied to protect the barrel from corrosion. This proprietary treatment surface-hardens the steel, extending the barrel's service life by reducing friction inside the bore, resulting in less bore surface wear over time.
