CMMG 38A530C-CT Dissent BR3 .308 Win 16.1" 10-Round Rifle

The CMMG 38A530C-CT Dissent BR3 .308 Win 16.1" rifle represents a modernized approach to intermediate-range tactical shooting, engineered for operators who demand precision without sacrifice of rapid target engagement. Chambered in .308 Winchester—the gold standard for professional marksmen across law enforcement and military contexts—this platform bridges the gap between AR-platform ergonomics and battle-proven rifle cartridge performance. Built for shooters operating in precision rifle disciplines, designated marksman roles, or home and property defense scenarios, the Dissent BR3 delivers the accuracy of a bolt gun with the handling characteristics and modularity operators expect from contemporary tactical platforms.

The 16.1-inch barrel provides optimal velocity and dwell time for .308 Winchester ammunition while maintaining a compact overall length of 39.5 inches, critical for vehicle transport, building clearance, and rapid deployment. At 12.8 pounds, the rifle achieves a practical balance between recoil management and point-ability—heavier than intermediate caliber ARs but lighter than traditional precision rifle systems. The BR3 designation references CMMG's precision-focused architecture, integrating features that enhance shot-to-shot consistency and reliability in field conditions. The 10-round magazine capacity ensures compliance in restricted jurisdictions while maintaining sufficient magazine changes for most tactical engagements. This configuration leverages .308 ballistics—superior penetration, wind deflection resistance, and effective range compared to 5.56 NATO—without requiring complete mechanical redesign of AR-platform operations.

Operators transitioning from standard AR-pattern rifles will find the Dissent BR3 immediately intuitive, as controls and ergonomics remain consistent with platform-standard manual of arms. Law enforcement designated marksmen, military support roles, and serious civilian marksmen benefit most from this platform's combination of intermediate rifle handling and full-power cartridge authority. The rifle accepts standard AR-platform accessories, optics mounting systems, and furniture, allowing rapid customization for mission-specific loads. Accuracy potential scales with shooter skill and ammunition selection; quality match-grade .308 Winchester loads will reliably deliver sub-MOA performance from a stable shooting position. For shooters requiring reliable, modular, precise rifle capability in an AR-familiar package, the CMMG 38A530C-CT Dissent BR3 .308 Win provides battle-tested engineering at a weight and ergonomic profile suitable for extended tactical operations.
