The CMMG 30A5C0FAB Dissent BR4 .300 Blackout 14.5" rifle delivers suppressed firepower in a compact, mission-ready package designed for operators who demand precision in confined spaces. Built for law enforcement tactical teams, military special operations, and serious civilian shooters, this platform excels in close-quarters and breaching scenarios where subsonic performance and modularity are non-negotiable. The .300 Blackout cartridge paired with a 14.5" barrel optimizes subsonic round performance while maintaining velocity for supers when needed, making it ideal for sound-suppressed operations without sacrificing terminal ballistics.
The BR4 platform features CMMG's combat-proven engineering with an 11-round magazine capacity that balances load-out weight against practical firepower for tactical applications. At 7.8 lbs unloaded, the rifle maintains a low profile while delivering the ergonomic controls and rail interface essential for mounting optics, lights, and suppressors. The Dissent series leverages CMMG's proprietary direct-impingement design, proven across thousands of operational deployments to provide reliable semi-automatic fire with minimal maintenance cycles between cleanings. The 14.5" barrel length—just under the NFA-regulated 16" threshold when properly pinned or welded with a flash hider—offers unprecedented maneuverability in vehicle and building operations.
Tactical professionals running suppressed .300 Blackout platforms will recognize the Dissent BR4 as a modular workhorse compatible with standard AR-15 accessories and aftermarket components across triggers, furniture, and sight systems. The 11-round magazine capacity accommodates both subsonic and supersonic ammunition, allowing seamless mission transitions without equipment changes. Law enforcement tactical units, military loadout planners, and civilian shooters serious about precision suppressed shooting will find this rifle delivers the balance of compactness, reliability, and performance required for real-world engagement profiles.
