CMMG Resolute 300 MK4 Six-Position Stock .223 Remington 5.56 NATO Graphite Black Rifle

Description

Product Overview

The CMMG Resolute 300 MK4 is a versatile AR-pattern rifle chambered for both .223 Remington and 5.56 NATO. Its 16.1-inch 4140 chrome-moly steel barrel uses a 1:7 twist rate and mid-length gas system for reliable cycling across a broad range of loads. A Geissele SSA two-stage trigger provides a refined trigger pull, while the CMMG RML15 M-LOK handguard offers flexible accessory mounting. The six-position CMMG RipStock, Magpul MOE pistol grip, ambidextrous controls, and CMMG SV muzzle brake complete a practical configuration for range use, training, and general-purpose rifle applications. The threaded muzzle uses a standard 1/2x28 pattern for compatible muzzle accessories.
