CMMG 64A190CAB Dissent BR4 6.5 Grendel 16.1" 11-Round Carbine

The CMMG 64A190CAB Dissent BR4 6.5 Grendel 16.1" 11-round carbine is purpose-built for shooters who demand precision at extended ranges without sacrificing ergonomic handling in tactical or competitive environments. The 6.5 Grendel cartridge delivers superior ballistic coefficient and energy retention compared to 5.56 NATO, making it ideal for mid-range engagements where velocity and accuracy are mission-critical. This platform serves law enforcement marksmen, military personnel, and serious civilian shooters who recognize that caliber selection directly impacts terminal performance and shot placement consistency downrange.

The 16.1-inch barrel provides the optimal balance between velocity, handling, and portability—a dimension proven effective in both confined and open-field operations. CMMG's Dissent platform incorporates a refined gas system that minimizes carrier tilt and extends component longevity under sustained fire, while the 11-round magazine capacity aligns with modern defensive doctrine and reduces reload frequency during extended engagement scenarios. The modular design allows for straightforward maintenance and accessory integration, with standard mil-spec mounting points for optics, lights, and rail systems. At 10.6 pounds, the overall weight remains manageable for duty carry while maintaining structural rigidity necessary for sub-minute-of-angle accuracy potential.

This carbine benefits operators and competitors who have transitioned beyond 5.56 platforms and prioritize ballistic performance in real-world distance shooting. The 6.5 Grendel's flatter trajectory and reduced wind drift make it particularly effective for tactical marksmanship training, designated marksman applications, and precision hunting. Compatibility with standard AR-pattern accessories and furniture ensures seamless integration into existing equipment ecosystems, while the proven Dissent reliability record provides confidence during critical missions or high-stakes competition. Law enforcement agencies and military units evaluating intermediate-range carbines will find the CMMG Dissent BR4 addresses the performance gap between assault rifle and dedicated precision rifle platforms.
