CMMG Rslt Mk4 5.56 NATO 16.1" 10-Round Rifle

The CMMG Resolute Mk4 5.56 NATO 16.1" rifle is a purpose-built platform for tactical professionals, law enforcement, and trained civilian operators who demand a compact, reliable carbine for duty or home defense. Built on the proven CMMG Resolute platform, this 5.56 NATO rifle combines the proven ballistics of NATO-standard ammunition with a manageable 16.1-inch barrel profile suited for vehicle operations, close-quarters environments, and tactical deployments. The 10-round magazine capacity reflects compliance requirements or precision-focused use cases where controlled ammunition economy matters alongside effective firepower.

The CMMG Resolute Mk4 configuration delivers proven 5.56 NATO performance with a 16.1-inch barrel that balances muzzle velocity retention and controllability in rapid-fire sequences. The Resolute series platform is known for its consistency in accuracy and reliability across diverse ammunition types and environmental conditions—critical factors in law enforcement and tactical scenarios where equipment redundancy cannot be tolerated. The compact profile and manageable weight distribution ensure stable handling in confined spaces and extended operational periods, while the 5.56 NATO chambering guarantees interoperability with standard military and commercial ammunition supplies used across North America.

This rifle is ideally suited for duty weapons systems, precision home defense platforms, and shooters who prioritize compact form factor without compromising stopping power or shot accuracy. The 10-round configuration appeals to competitive shooters, compliance-conscious jurisdictions, and operators who value magazine-fed precision over volume. The 16.1-inch barrel strikes a critical balance for shooters operating in vehicles, buildings, or confined tactical environments where a full-length rifle becomes an operational liability. Compatibility with standard 5.56 NATO ammunition and AR-pattern accessories ensures rapid resupply and customization options, while the Resolute platform's track record in professional service environments provides confidence in sustained reliability and parts availability.
