CMMG Inc. · Rifle · In Production · 2018
Overview
The CMMG Resolute Mk3 is a large-frame AR-10 pattern semi-automatic rifle chambered in .308 Winchester (7.62x51mm NATO) with 6.5 Creedmoor also offered. Built on CMMG's Mk3 platform - based on the Gen 1 DPMS high-pattern LR-308 design - the Resolute Mk3 pairs the carbine-length 16.1-inch medium-taper 416 stainless steel barrel with billet 7075-T6 aluminum upper and lower receivers. The rifle ships with CMMG's ZEROED components including an ambidextrous charging handle, drop-in single-stage trigger, and pistol grip, plus a CMMG SV muzzle brake on a 5/8-24 threaded muzzle and a rifle-length gas system. A 15-inch M-LOK free-float handguard, RipStock collapsible buttstock, and Cerakote finish complete the build. Feeding from 20-round Magpul PMAG LR/SR magazines, the Resolute Mk3 delivers full-power rifle performance in a relatively compact, lightweight package.
