CMMG AR-15 Magazine Features The CMMG AR-15 Magazine is built to CMMG s Mk4/AR15 platform specifications giving shooters a magazine engineered to feed reliably across a wide range of AR-pattern rifles chambered in 5.56mm or .223 Rem. The 30-round capacity matches the standard configuration most AR-15 owners rely on for range use training and home defense applications.

Consistent feeding and reliable lock-up in the magazine well are essential qualities for any AR-15 magazine and CMMG s manufacturing background in AR-platform components supports that reliability.
