What Makes This Different

The Resolute MK4 features CMMG's precision-machined upper and lower receivers with enhanced tolerances for improved accuracy. The 16.1-inch barrel utilizes a 1:7 twist rate optimized for both 55-grain and heavier projectiles, while the mid-length gas system reduces felt recoil and extends component life. The Coyote Brown Cerakote finish provides superior corrosion resistance compared to standard phosphate coatings.
