CMMG 55AFC5B-FDE 5.56x45mm NATO 30 Rd FDE AR-15/MK4 Magazine

The CMMG 55AFC5B-FDE is a 30-round detachable magazine chambered in 5.56x45mm NATO, engineered to feed reliably in MK4 and AR-15 platform rifles and carbines.

Built around an advanced polymer body with CMMG's signature textured styling, this magazine stands up to the elements while providing positive grip in adverse conditions. The internal geometry is tuned for smooth, consistent feeding, and the Flat Dark Earth finish coordinates cleanly with similarly colored components on modern sporting rifles.

At 8.3" long, this new condition magazine drops into a standard AR-15 magwell and is ready for duty, range, or competition use right out of the package.
