CMMG Resolute MK4 5.7 X 28 16.1″ Barrel 32-Rounds

CMMG Resolute MK4 Features

This rifle is built around the Radial Delayed Blowback operating system, enhancing reliability and reducing felt recoil, making it exceptionally comfortable to shoot. The CMMG ZEROED Muzzle Brake further improves this by dampening recoil and minimizing muzzle rise. The firearm is equipped with a CMMG EML15 M-LOK handguard, allowing for easy attachment of accessories without adding unnecessary weight.

The upper and lower receivers are constructed from Billet 6061 T6 and Forged 7075 T6 Aluminum, respectively, ensuring durability while maintaining a light overall weight of 6.4 lbs. The finish is a robust Cerakote, providing excellent resistance to wear and corrosion. Additionally, the CMMG ZEROED Ambi Charging Handle and the ZEROED Drop-In Trigger system contribute to the rifle’s smooth operation and user-friendly design.
