The CMMG 30A240AAB RESOLUTE MK4 300 Blackout 14.5" AR rifle combines the platform's modular versatility with 300 BLK ballistics optimized for suppressed, subsonic performance. Originally engineered to maximize compatibility with standard M4/AR-15 parts while delivering heavy .30 caliber impact downrange, the 300 Blackout cartridge excels in shorter barrel configurations—making this 14.5-inch rifle ideal for close-quarters home defense, suppressed operations, and tactical environments where barrel length and overall package size matter.
Built on CMMG's RESOLUTE MK4 AR-15 platform, this rifle features a free-floating EML handguard with full-length M-LOK slots on both sides and bottom, plus M-LOK integration between the top Picatinny rail for maximum accessory mounting flexibility. The 14.5-inch barrel supports both subsonic and supersonic 300 BLK loads, delivering terminal performance suitable for home defense while the handguard geometry minimizes bulk. At 8.45 pounds, the rifle balances controllability with the rotating mass needed for reliable operation across ammunition variants. The AR-15 architecture ensures straightforward maintenance and field-proven ergonomics familiar to operators and enthusiasts.
This platform serves home defenders, tactical rifle users, and shooters seeking suppressed capability without a large footprint or specialized training. The 300 Blackout cartridge's subsonic performance eliminates the need for hearing protection when running quality suppressors, a significant advantage in defensive scenarios. The RESOLUTE MK4 configuration bridges duty-grade reliability with the modularity expected of modern AR systems, allowing users to adapt the rifle to specific mission requirements through standard M-LOK and Picatinny interfaces.
The 300 Blackout category has matured into a proven platform for suppressed rifle work, patrol carbines, and dedicated SBR builds where short barrels remain necessary. CMMG's RESOLUTE line emphasizes reliability and user-driven design, positioning this rifle as a serious option for buyers evaluating 300 BLK systems at the 14-inch barrel length.
