Cmmg Rslt Mk4 338 Arc 16.1" 10rd Ab

The CMMG Resolute Mk4 in .338 ARC with a 16.1-inch barrel is a modern semi-automatic rifle engineered for precision and versatility in tactical, hunting, and range applications. Chambered in .338 ARC—a purpose-built intermediate cartridge optimized for barrel lengths between 12 and 20 inches—this rifle delivers ballistic performance superior to 7.62×39 while maintaining the ergonomic and modular platform advantages CMMG is known for. The 16.1-inch barrel strikes an optimal balance between velocity, handling, and portability, making this configuration suitable for both close-quarters work and extended-range engagements.

Built on CMMG's proven Mk4 platform, the Resolute features a Cerakote Armor Black finish designed to resist corrosion, wear, and the elements encountered during sustained field use. The rifle weighs 10.5 lbs, keeping it manageable for extended carry and allowing shooters to maintain precision through multiple strings of fire. The 10-round magazine capacity (included) complies with restrictive jurisdictions while providing practical ammunition reserves for training and deployment scenarios. The .338 ARC cartridge generates moderate recoil compared to larger rifle calibers, reducing fatigue during training sessions and enhancing shot-to-shot recovery for faster follow-ups.

This rifle is built for operators and serious shooters who prioritize intermediate ballistics in a compact, modular platform. The .338 ARC has gained adoption among tactical trainers, precision rifle competitors, and hunters seeking effective performance at intermediate distances without the recoil penalty of full-power rifle cartridges. CMMG's Mk4 design ensures compatibility with standard AR-15 upper/lower receiver interfaces and a broad aftermarket ecosystem for customization and upgrades. Whether configured for patrol, training, competition, or field hunting, the Resolute Mk4 provides a reliable foundation for shooters building or upgrading their tactical rifle systems.
