The CMMG 30A240AAB RESOLUTE MK4 .300 Blackout 14.5" AR rifle is purpose-built for operators and tactical professionals who demand a versatile platform capable of handling both subsonic and supersonic ammunition. This rifle excels in close-quarters combat, breaching operations, and suppressed tactical deployments where traditional 5.56 NATO may fall short on ballistic efficiency.
Chambered in .300 Blackout, the 14.5-inch barrel length strikes a critical balance between velocity retention and maneuverability in confined spaces. CMMG's RESOLUTE MK4 design leverages the proven AR platform architecture with refinements specific to optimizing performance with both subsonic and supersonic ammunition. The .300 Blackout chamber ensures reliable feeding and accuracy across ammunition variations, which is critical when rounds vary in powder burn rates and velocity windows.
At 8.45 pounds, this rifle maintains a field-manageable weight profile without compromising structural rigidity or component durability. The modular AR platform allows for optic mounting, rail integration, and accessory compatibility with standard mil-spec components, ensuring long-term configurability as mission requirements evolve. Tactical professionals, armored operators, and precision riflemen will benefit from this platform's combination of stopping power and adaptability.
