Product Overview
The CMMG Resolute Mk4 is a lightweight AR-pattern rifle chambered for both .223 Remington and 5.56 NATO. Its 16.1-inch 4140 chrome moly steel barrel uses a mid-length gas system and a 1:7-inch twist, providing a versatile setup for training, range use, and defensive applications. The rifle features CMMG’s EML15 M-LOK handguard, RipStock buttstock, Zeroed trigger, Zeroed pistol grip, ambidextrous controls, and a Zeroed SV muzzle brake. A 1/2x28 threaded muzzle supports compatible accessories, while the top rail provides a straightforward mounting point for an optic.
