CMMG runs a direct-impingement gas system through a 16.1-inch, 416 stainless steel barrel with a 1:10-inch twist and a CMMG ZEROED muzzle brake threaded 5/8×24, wraps the barrel in a CMMG EML15 M-LOK handguard, and finishes the rifle in Cerakote. The carbine features CMMG’s ambidextrous ZEROED charging handle and pistol grip, a RipStock on a 6-position fastback receiver extension with an ambi sling plate, a ZEROED drop-in trigger, and a 60/90-degree ZEROED safety selector. It ships with a 20-round Magpul PMAG and weighs about 8 pounds. Among AR-platform rifles in the AR rifles category, the Resolute Mk3 favors shooters who want a heavy-hitting .308 carbine in a lightweight, ergonomic package.
