CMMG RESOLUTE Mk57 Radial Delayed Blowback 5.7x28mm FN Armor Black Cerakote Rifle

Description

Product Overview

The CMMG RESOLUTE Mk57 is a lightweight 5.7x28mm FN carbine built around CMMG's radial delayed blowback operating system. Its 16.1-inch threaded barrel delivers a longer sight radius and improved ballistic performance than a typical pistol or short-barreled configuration, while the low-recoil cartridge supports comfortable, controlled shooting. The rifle accepts FN Five-seveN-style magazines and maintains familiar AR-pattern functionality, including last-round bolt hold open. An EML15 M-LOK handguard, ZEROED components, ambidextrous charging handle, 60/90-degree safety selector, and adjustable RipStock provide a practical setup for range use, training, and defensive applications. The Armor Black Cerakote finish protects the aluminum and steel components and gives the rifle a durable, uniform appearance.
