CMMG 55A060BCT RESOLUTE MKG 5.56 14.5 COY

The CMMG 55A060BCT RESOLUTE MKG 5.56 14.5" COY is a purpose-built 5.56 NATO carbine engineered for operators who demand a compact, modular platform without compromise on usability or accessory integration. The 14.5-inch barrel delivers efficient velocity for the 5.56x45mm cartridge while maintaining a handling profile suited to close-quarters environments, vehicle operations, and confined spaces where shorter overall length provides tactical advantage. Weighing 8.8 lbs fully assembled, this rifle achieves the balance between maneuverability and controllability that professional end users and serious enthusiasts expect.

The RESOLUTE platform ships with CMMG's Enhanced Modular Lightweight (EML) handguard featuring full-length M-LOK mounting slots on both sides and bottom, plus M-LOK bridging between top Picatinny sections. This multi-interface approach ensures maximum versatility for lights, lasers, vertical grips, and other mission-essential attachments. The rifle is equipped with ZEROED drop-in components—trigger, pistol grip, trigger guard, and 60/90-degree ambi safety—allowing operators to customize ergonomics and trigger performance without gunsmithing. The ambidextrous safety is critical for cross-dominant shooters or operators transitioning between shooting positions in dynamic scenarios.

This CMMG RESOLUTE MKG carbine is suited for patrol rifle duty, tactical training, home defense, and precision target work where 5.56 ballistics and cartridge availability align with mission requirements. The 5.56 NATO round remains the professional standard for military and law enforcement applications, with a mature ecosystem of ammunition loadings and spare parts. Operators evaluating 5.56 carbines for sale will find the 14.5-inch barrel length offers a practical sweet spot—short enough for CQB handling, long enough to extract effective velocity from the cartridge.

The CMMG RESOLUTE platform has earned recognition in the tactical community for build quality and genuine modularity. Unlike entry-level ARs that offer handguards with minimal attachment points, the EML system on this rifle supports professional-grade configuration flexibility. The ambidextrous controls and drop-in trigger options reflect a design philosophy oriented toward operator efficiency rather than cost-cutting.
