CMMG Resolute MK4 300 Blackout 16.1″ Semi-Auto Rifle – 30rd, Midnight Bronze Cerakote

The CMMG Resolute MK4 in 300 AAC Blackout delivers a refined, feature-packed modern sporting rifle wrapped in a striking Midnight Bronze Cerakote finish. Built on a proven AR platform, this semi-automatic rifle is engineered for reliability, versatility, and performance straight out of the box.

At the heart of the Resolute MK4 is a 16.1″ 4140 chrome moly barrel with a 1:7″ rate of twist, optimized for stabilizing both supersonic and subsonic 300 Blackout loads. The .750″ carbine-length gas system ensures smooth, consistent cycling, while the 5/8-24″ threaded muzzle and included CMMG Zeroed SV Muzzle Brake provide suppressor-ready versatility and reduced felt recoil.

The rifle ships fully equipped with CMMG’s ergonomic RipStock adjustable buttstock and EML15 M-LOK handguard, giving you a rigid, lightweight platform for accessories and optics. The Zeroed pistol grip and Zeroed trigger round out a comfortable, intuitive control package, while fully ambidextrous controls make this rifle an excellent choice for left- and right-handed shooters alike.

With a 6.44 lb. weight, a 30-round detachable magazine, and an overall length of 32.5″, the Resolute MK4 strikes an ideal balance of maneuverability and capability for home defense, range use, or hunting applications.
