What Makes This Different

The Resolute MK4 features CMMG's radial delayed blowback operating system, which provides smoother cycling and reduced felt recoil compared to traditional direct impingement systems. The 16.1-inch barrel offers optimal velocity for 300 Blackout cartridges while maintaining maneuverability. The midnight bronze Cerakote finish provides superior corrosion resistance and reduced glare compared to standard black finishes.
