CMMG RESOLUTE Mk57 5.7x28mm FN Cerakote Rifle

Description

Product Overview

The CMMG RESOLUTE Mk57 is a compact semi-automatic rifle chambered in 5.7x28mm FN and engineered around CMMG's radial delayed blowback operating system. It accepts FN Five-seveN-style magazines while retaining familiar AR-pattern controls and last-round bolt hold open functionality. The 16.1-inch SBN-finished 4140CM barrel uses a 1:9 twist and is threaded 1/2x28, with a CMMG ZEROED muzzle brake installed. A lightweight billet aluminum upper, forged aluminum lower, EML15 M-LOK handguard, ZEROED ambidextrous charging handle, drop-in trigger, six-position receiver extension, and RipStock create a capable carbine-length package. The Cerakote finish adds durable surface protection, while the receiver rail supports the installation of an optic.
