CMMG 54AFC44 Mk4/AR-15 5.7x28mm 10-Rd Black Magazine

The CMMG 54AFC44 is a factory 5.7x28mm detachable box magazine designed as a Gen II conversion magazine for the AR-15 platform. It feeds from a 10-round capacity and is finished in a low-glare matte black coating that blends cleanly with most rifle builds.

Purpose-built for CMMG's 5.7x28 Radial Delayed Blowback uppers, this magazine is also compatible with any Mil-Spec AR-15 lower receiver when paired with an appropriate 5.7x28 upper. The Gen II design delivers reliable feeding for the high-pressure 5.7x28mm cartridge, making it an essential spare or replacement for CMMG Mk4 and other 5.7x28 AR configurations. Each package contains one 10-round magazine.
