CMMG RESOLUTE MK4 | .300 BLK 16.1in | 30AE70ACT

The CMMG RESOLUTE MK4 is a carbine-length AR platform chambered in .300 BLK with a 16.1-inch barrel and Coyote Tan Cerakote finish. It is built on CMMG’s Mk4 receivers and ships with a suite of ZEROED components and a Magpul 30rd PMAG. For a versatile optic under $1,000 that pairs well with this carbine-length platform consider the Vortex Viper PST Gen II 1-6×24, which supports fast target acquisition and close-to-midrange engagement.

Common applications for this configuration include medium-game hunting with appropriate supersonic loads and practical/competition shooting at typical AR carbine distances.
