This RESOLUTE Mk4 is built on CMMG’s aluminum Mk4 receivers and finished in a non-standard Charcoal Green Cerakote applied to the upper, lower, handguard, and stock. The color provides added durability while giving the rifle a distinct, cohesive appearance.
The rifle’s 16" 4140 chrome-moly steel barrel is salt-bath nitride treated for extended life, cut with a 1:7" twist to stabilize a wide range of 5.56 NATO and .223 Rem. bullet weights, and threaded 1/2-28 to accept the factory-installed CMMG ZEROED multi-port muzzle brake.
CMMG’s ZEROED ambidextrous safety, extended magazine release, bolt catch, and charging handle let both right- and left-handed shooters run the gun efficiently. The proprietary Fastback RIPSTOCK offers six-position adjustability and a lightning-fast deploy setting that locks at the preset length of pull.
The lightweight EML-15 free-float handguard is machined from 6061-T6 aluminum, features 12-o’clock M-LOK slots with a partial top rail, and leaves the barrel completely free of contact for consistent accuracy. Combined with the aluminum receivers and polymer furniture, the rifle remains easy to maneuver without sacrificing durability.
Factory MSRP is $1,899.95, making this example a turnkey, premium AR-15 platform ready for optics, accessories, and range use straight out of the box.
