CMMG 55A080BCT Dissent BR4 5.56 NATO 14.5" 11-Round Threaded Barrel Rifle

The CMMG 55A080BCT Dissent BR4 is a California-compliant modern sporting rifle engineered for precision, modularity, and field reliability. Chambered in .223 Remington/5.56 NATO with a 10+1 capacity and 14.50-inch black nitride medium taper threaded barrel, this platform delivers consistent accuracy while maintaining the compact profile tactical operators demand. The coyote tan Cerakote aluminum Picatinny rail receiver provides a rugged upper for mounting optics, lasers, and tactical accessories, while the Magpul SGA black polymer stock ensures a secure, adjustable cheekweld and repeatable shoulder positioning under stress.

The 14.50-inch barrel length represents a proven compromise in the 5.56 NATO platform—long enough to extract velocity from the cartridge for effective range performance, yet short enough for vehicle operations and tight indoor environments where full-length rifles become liabilities. Black nitride coating on the barrel resists corrosion and reduces glint, critical for sustained operations in variable climates. The medium taper profile balances weight and rigidity; a thinner profile reduces point-of-impact shift under sustained fire, while the threaded muzzle accepts suppressors, flash hiders, or compensators without additional modifications. The Picatinny rail receiver is forged aluminum—standard across modern tactical platforms—and accepts industry-standard optic mounts and accessory systems. Magpul's SGA stock is known for consistent geometry and durable polymer construction, providing operators with repeatable positioning across training and duty applications.

This configuration serves law enforcement patrol, precision-focused civilians, competitive shooters, and home defense scenarios where California's 10-round magazine capacity and fixed-stock compliance are required or preferred. The .223 Remington/5.56 NATO cartridge offers low recoil impulse for follow-up accuracy, abundant ammunition availability, and proven terminal performance across disciplines. Weighing 11.8 pounds, the rifle remains manageable for extended handling without fatigue—important for training courses and duty carry. The coyote tan receiver finish integrates well with modern tactical gear, and the modular Picatinny platform means this rifle adapts to mission-specific optics and accessories without gunsmithing.
