These are CMMG Gen II 9AR magazines engineered for 9mm AR-style platforms. They provide a compact, polymer-bodied option with dimensions that closely match common 5.56 AR-15 magazines for improved compatibility with existing mag pouches and carriers. The magazines are intended for use in Mk4/AR-15 lower receivers when paired with a CMMG 9mm radial delayed blowback upper.
