CMMG Dissent BR4 6mm ARC CA Compliant 16.1" 10+1 Black Cerakote

The CMMG Dissent BR4 delivers precision rifle performance in a California-compliant configuration, chambered in the versatile 6mm ARC cartridge. This straight-pull bolt-action platform bridges the gap between traditional bolt guns and modern sporting rifles with its innovative design.

What Makes This Different

Unlike conventional bolt-action rifles, the Dissent BR4 utilizes CMMG's straight-pull bolt system that cycles faster than traditional turn-bolt actions while maintaining single-shot accuracy. The 6mm ARC chambering provides superior ballistics compared to .223/5.56, delivering flatter trajectories and better wind resistance at extended ranges. California compliance is achieved through a fixed magazine system that requires disassembly for loading, meeting all state requirements without compromising the rifle's core functionality.

Key Features

• 6mm ARC chambering for enhanced long-range performance over standard AR calibers
• 16.1-inch barrel with Black Armor Cerakote finish for corrosion resistance
• Magpul SGA stock provides adjustable length of pull and cheek height
• Zeroed drop-in single-stage trigger for consistent, crisp break
• Aluminum receiver construction with integrated Picatinny rail
• Straight-pull bolt operation for rapid follow-up shots
• 10+1 capacity with California-compliant fixed magazine system

The 6mm ARC cartridge excels in precision shooting applications, delivering match-grade accuracy at distances where .223 Remington begins to lose effectiveness. Competition shooters benefit from the cartridge's inherent accuracy and reduced wind drift, while hunters appreciate the improved terminal performance on medium game. The straight-pull action allows for faster cycling than traditional bolt guns while maintaining the precision expected from a dedicated accuracy platform.
