CMMG 54AFCC8 Replacement Magazine Gen 2 5.7x28mm 32-Rd Polymer Black

The CMMG 54AFCC8 is a Gen 2 replacement 32-round magazine purpose-built for 5.7x28mm AR-platform shooters. Engineered to feed CMMG's 5.7x28 Radial Delayed Blowback uppers as well as Mk4 and Mil-Spec AR-15 lower receivers, this magazine keeps your 5.7x28 build running with proven reliability.

The body is molded from durable black polymer with a textured grip surface for positive handling during fast magazine changes. The Gen 2 update brings upgraded feed lips over the original design, smoothing feeding geometry and extending service life. At a 32-round capacity, this is the standard-capacity option in CMMG's 5.7 conversion magazine lineup (a 10-round variant is also available for restricted states).

Whether you run a dedicated CMMG 5.7x28 upper or an MK4 / Mil-Spec AR-15 lower converted to 5.7x28, the 54AFCC8 is a direct-fit replacement magazine ready to feed. One magazine is included per purchase.
