Description

Product Overview

The CMMG RESOLUTE Mk4 is a modular 5.7x28mm FN carbine built on the Mk4 AR15 platform. Its radial delayed blowback operating system provides reliable cycling while maintaining familiar AR-pattern controls and compatibility with CMMG 32-round magazines that fit the standard AR15 magwell. The rifle features a 16.1-inch 4140CM SBN barrel with a 1:9 twist, a CMMG ZEROED muzzle brake, and a 1/2x28 threaded muzzle. A billet aluminum upper receiver, forged lower receiver, EML15 M-LOK handguard, ZEROED drop-in trigger, ambidextrous charging handle, and RipStock create a practical and adaptable carbine configuration. The FDE/Tan finish gives the rifle a distinctive appearance, while the top rail supports the addition of an optic.
