Cmmg Resolute Mkg Fixed 45Acp 16.1 Coyote Tan

The CMMG Resolute MkG Fixed .45 ACP carbine bridges the gap between the portability of a pistol and the range capability of a full-size rifle. Chambered in .45 ACP—one of the most trusted and battle-proven pistol calibers ever made—this 16.1-inch rifle delivers the ballistic performance of a centerfire carbine while accepting standard Glock-pattern magazines that shooters already know and trust. At 6.0 lbs and 32.5 inches overall, it's nimble enough for hunting, home defense, or the range without sacrificing the velocity and trajectory you need at distance.

The Resolute's backbone is CMMG's fixed ejector radial delayed blowback operating system—a refined evolution of proven piston-style reliability that cycles .45 ACP efficiently in a compact platform. You get a billet 6061 T6 aluminum upper and forged 7075 T6 lower receiver, both precision-built for durability. The 4140CM barrel wears a 1:16 twist and threads at 0.578 x 28 to accept the included CMMG ZEROED muzzle brake, which helps manage recoil and muzzle rise. Cerakote finish in Coyote Tan resists corrosion and blends into field environments.

Modularity and ergonomics are baked in. The EML15 M-LOK handguard sheds unnecessary weight while keeping mounting slots where you need them—3, 6, 9, and 12 o'clock—so you can attach lights, lasers, or other gear without bulk. The ambidextrous charging handle, ZEROED drop-in trigger, 60/90-degree safety selector, and RipStock with integrated sling attachment make this rifle equally at home for left or right-handed shooters. A carbine-length buffer tube and 6-position receiver extension keep the platform balanced and tunable for your ammunition and shooting style.

Whether you're hunting medium game, running precision drills at the range, or building a truck gun that actually performs, the Resolute MkG in .45 ACP is a serious, no-nonsense carbine that doesn't compromise on weight, ergonomics, or mechanical reliability.
