Design Philosophy
CMMG engineered the Resolute to be equally at home in the field or at the range. The M-LOK handguard reduces unnecessary weight while maintaining ample real estate for mounting lights, lasers, or other mission-critical accessories. The omission of full-length Picatinny rail sections keeps the rifle balanced and maneuverable without sacrificing modularity.
Why 8.6 Blackout?
This cartridge delivers superior ballistics compared to its predecessors when running subsonic ammunition. Shooters appreciate the increased velocity potential, flatter trajectory, and enhanced terminal performance—all while maintaining the signature quiet operation that makes suppressed rifles so practical for hunting and training.
The Resolute MK3 is a rifle that belongs anywhere serious shooters gather.
