CMMG Inc. · Carbine · In Production · 2018
Overview
The CMMG Resolute Mk4 is a carbine-length AR-15 pattern semi-automatic rifle built on CMMG's full-size Mk4 platform and positioned between the company's compact Banshee pistols and long-range Endeavor rifles. Chambered standard in 5.56x45mm NATO with a 16.1-inch (or 14.5-inch pinned-and-welded to 16.1") medium-taper barrel, the Resolute Mk4 ships with CMMG's ZEROED line of enhanced components - an ambidextrous charging handle, ambidextrous safety selector, drop-in single-stage trigger, and oversized bolt catch. Aircraft-grade 7075-T6 aluminum upper and lower receivers carry a durable Cerakote finish offered in over a dozen colors, while the M-LOK free-float handguard provides 3, 6, 9, and 12 o'clock mounting. CMMG offers the Resolute Mk4 across an unusually broad caliber range including 5.56mm, .300 Blackout, .350 Legend, .22 ARC, 6mm ARC, 6.5 Grendel, and pistol calibers, making it one of the most configurable carbines in the lineup.

Notes
MSRP approximately $1,599. The Resolute line is CMMG's carbine-length family (16.1" barrels) sitting between the compact Banshee and the long-range Endeavor. The 'Mk4' designation indicates the AR-15 (small-frame) platform; CMMG also offers the Resolute in Mk47 (7.62x39), Mk57 (5.7x28mm), and Mk3 (.308/AR-10) platform variants. All Resolute rifles use a rifle- or mid-length gas system with direct impingement, though Radial Delayed Blowback is available in pistol-caliber configurations.
Background
CMMG renamed and consolidated its earlier numbered '100/200/300' series rifles under the Resolute branding to create a clearer product identity for its carbine-length offerings, manufactured in Boonville, Missouri.
