For operators and precision-focused shooters who want the extended ballistic capability of larger platforms without the weight and bulk, a purpose-built AR15-format rifle in 6mm ARC bridges the gap. Tactical use, long-range accuracy, and user-adjustable ergonomics are priorities when selecting a modern semi-auto for dynamic work.
CMMG RESOLUTE MK4 is designed around the 6mm ARC to deliver AR10-level performance in an AR15 chassis while retaining maneuverability. 
The platform ships ZEROED with a drop-in single stage trigger and includes a CMMG 10rd magazine, giving you an out-of-the-box firing solution ready for optics and mission configuration. Shop this product
Design and Key Features
Built on a Black Armor Cerakote Picatinny rail aluminum receiver, the rifle pairs a 16.10″ Black Nitride medium taper threaded barrel with an EML 15″ M-LOK handguard. Full-length M-LOK slots on both sides and the bottom, plus M-LOK between top rail sections, provide flexible accessory mounting without excess weight. The included Black Synthetic CMMG 6 Position Rip Stock and ergonomic pistol grip balance control and comfort for extended use.

Controls and Zeroed Components
Controls are fully ambidextrous where it matters: 60/90-degree ambi safety, ambi mag catch, extended mag release button, ambi charging handle, bolt catch — and a polymer dust cover for dependable operation in adverse conditions. The zeroed drop-in single stage trigger is tuned for predictable pull and enhanced follow-through, making precise shots more repeatable in tactical scenarios.
6mm ARC: Ballistics and Tactical Application
The 6mm ARC provides flatter trajectory, reduced wind drift, and higher retained energy at extended ranges compared with typical .224-caliber loads in standard AR15s. This makes the platform ideal for designated marksman roles, patrol rifles where extra reach matters, and competitions requiring long-range precision without the AR10 footprint.
Value and Buying Info
Priced at $1,550.99, the package includes the muzzle brake and a 10-round CMMG magazine, delivering a complete, mission-ready system. The reputation of Cmmg for reliable, purpose-built AR solutions makes the RESOLUTE MK4 a notable choice for teams and serious shooters seeking a compact long-range solution.
