The CMMG 30A240ASG RESOLUTE MK4 300 Blackout 14.5-inch rifle delivers precision rifle performance in a compact, purpose-built platform optimized for suppressed and subsonic operations. Built on the proven AR-15/M4 modular foundation, this .300 BLK carbine combines efficiency, modularity, and real-world versatility for specialized tactical applications where shorter barrel length and sound signature matter.
The 14.5-inch barrel length optimizes .300 Blackout for subsonic ammunition while maintaining reasonable velocity for duty-grade performance. The rifle weighs 8.4 pounds, keeping it manageable for extended operations or CQB environments. The EML (Enhanced Modular Lightweight) handguard features full-length M-LOK slot coverage on both sides and bottom, plus integrated M-LOK sections between the top Picatinny rail—giving operators unrestricted options for mounting lights, lasers, grips, and other mission-critical accessories. The MK4 platform ensures compatibility with standard AR-15 components, magazines, and ammunition components, reducing logistics complexity in mixed-inventory environments.
This rifle excels for operators and advanced civilian shooters prioritizing suppressed duty, close-quarters home defense, and training environments where noise and recoil management are operational constraints. The .300 Blackout cartridge was specifically engineered to deliver heavy .30-caliber bullet performance from short barrels while maximizing subsonic load utility—a ballistic advantage unavailable in standard 5.56 platforms. The compact overall length (41 inches) and modular design make it suitable for vehicle storage, building entry, and confined-space drills common to tactical training and professional applications.
The RESOLUTE MK4 300 Blackout represents CMMG's precision engineering in the specialty rifle category. For shooters and professionals evaluating .300 BLK carbines, this model delivers verified modularity and real-world feature integration at a price point reflecting current market conditions for suppressed-duty platforms.
