Design and key features

The Mk4 RESOLUTE centers on modularity and control. The M-Lok handguard offers low-profile accessory mounting without excess weight, allowing lights, grips, and pressure switches to be positioned exactly where you need them. The included muzzle brake reduces felt recoil and muzzle rise during rapid strings of fire, aiding follow-up shot speed in defensive scenarios. A QD sling ring provides fast attachment for a single-point or two-point sling, enhancing retention and weapon transition drills.

Ergonomics, controls, and handling

Ambidextrous controls make the CMMG MK4 RESOLUTE suitable for left- and right-handed shooters and for shooters who need to operate the rifle from unconventional firing positions. The adjustable stock permits quick length-of-pull changes for plate carriers or layered clothing. The 1/7″ barrel twist optimizes stabilization for a broad range of common bullet weights, supporting consistent accuracy across duty and defensive loads.
