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

The CMMG 55A080BCT Dissent BR4 5.56 NATO rifle with 14.5-inch threaded barrel represents a purpose-built modern sporting rifle designed for shooters who demand California-compliant operation without compromising ergonomics or reliability. Built on a proven direct-impingement platform, this rifle delivers the accuracy and handling characteristics expected in professional and civilian tactical applications. The Dissent BR4 platform is engineered for operators who prioritize adaptability, maintenance accessibility, and real-world performance in restricted regulatory environments.

The 14.5-inch barrel length balances velocity retention in 5.56 NATO with practical maneuverability, while the threaded muzzle allows integration of suppressors, flash hiders, or muzzle devices once local regulations permit. The rifle ships with an 11-round magazine configuration, meeting California's capacity restrictions while maintaining the platform's standard internal geometry for future compliance flexibility. Weighing 11.8 pounds, the Dissent BR4 delivers a balanced ergonomic profile—light enough for extended use, yet substantial enough to manage recoil and sustain accurate fire. The rifle's modular design supports standard AR-pattern accessories, enabling customization of furniture, optics mounts, and ancillary gear to match individual mission requirements or shooting disciplines.

This platform appeals to California-based shooters, law enforcement training programs, and operators who operate under restrictive state compliance mandates. Civilian sport shooters, tactical competitors, and precision rifle enthusiasts will find the Dissent BR4's short-action profile and threaded barrel ideal for both stock configuration and suppressor-ready setups. Installation of aftermarket grips, stocks, and optic systems follows standard AR-platform procedures; no specialized tools or gunsmithing are required. The rifle's reliability record and CMMG's manufacturing reputation make it a dependable choice for high-round-count training, qualification courses, and duty application in compliant jurisdictions.
