The AR-15 market rewards rifles that balance weight, durability and modularity; the CMMG RESOLUTE MK IV is designed to hit that balance with purpose. Its combination of a precision barrel, low-recoil muzzle device, and an advanced M-LOK handguard makes it an attractive option for shooters who demand a lightweight, versatile platform for range work, duty use, or training.

CMMG RESOLUTE MK IV

Design and construction

The Resolute MK4 centers on a 4140 chrome moly steel barrel finished in salt-bath nitride. That combination gives you the accuracy stability of a quality steel barrel with enhanced surface hardness and corrosion resistance from nitride treatment. The rifle’s robust cerakote finish further improves environmental resistance for users operating in varied conditions.

Barrel, muzzle and recoil mitigation

The threaded muzzle paired with a Zeroed muzzle brake is configured to reduce felt recoil and speed follow-up shots — a practical benefit for defensive drills and timed strings. Threading preserves the option to mount suppressors or alternative muzzle devices without sacrificing the factory brake’s performance.

Controls and ergonomics

Included Zeroed accessories — ambidextrous magazine catch, safety selector and charging handle — deliver true bilateral control. These parts simplify manipulation under stress and make the rifle accessible for left- and right-handed shooters without aftermarket upgrades.

Accessory compatibility

The CMMG EML15 handguard with M-LOK slots at 3, 6 and 9 o’clock and Picatinny rail sections at the top front and rear is a modular foundation for optics, lights, lasers, bipods and vertical grips. This native M-LOK architecture keeps weight down while preserving a broad range of accessory options for mission-specific builds.
