Product Overview
The CMMG Resolute 300 MkG is an AR-pattern semi-automatic rifle chambered in .45 ACP and configured for large-frame Glock-style magazines. Its 16.1-inch 4140 chrome moly steel barrel uses a 1:16-inch twist and features .578x28 threading with a CMMG SV muzzle brake. Forged 7075-T6 aluminum receivers, a CMMG RML15 M-LOK handguard, and a six-position CMMG RipStock provide a durable and adaptable platform. A Geissele SSA two-stage trigger supports a refined trigger pull, while the ambidextrous safety selector and charging handle accommodate flexible handling. The rifle includes one 26-round SGM Tactical magazine.
