CMMG Dissent BR4 6mm ARC CA Compliant 16.1" Coyote Tan Rifle

The CMMG Dissent BR4 delivers precision shooting capabilities in a California-compliant configuration, chambered in the versatile 6mm ARC cartridge. This rifle combines CMMG's proven engineering with thoughtful component selection to create a platform optimized for accuracy and reliability.

What Makes This Different

Built around CMMG's proprietary action system, the Dissent BR4 features a rigid aluminum receiver finished in durable Coyote Tan Cerakote for enhanced corrosion resistance. The 16.1-inch barrel length maximizes velocity while maintaining maneuverability, while the Zeroed drop-in single-stage trigger provides consistent break characteristics. The Magpul SGA stock offers adjustable length of pull and enhanced ergonomics compared to standard A2-style stocks.

Key Features

• 6mm ARC chambering for superior ballistic performance and reduced wind drift
• 16.1-inch barrel with optimized twist rate for heavy match bullets
• Coyote Tan Cerakote finish on aluminum receiver for corrosion protection
• Magpul SGA stock with adjustable length of pull (12.5" to 13.5")
• Zeroed drop-in single-stage trigger with crisp, consistent break
• California-compliant configuration with 10-round magazine capacity
• Standard Picatinny rail interface for optics mounting

The 6mm ARC cartridge excels in precision applications, delivering flatter trajectories and less wind drift than traditional .223/5.56 loads. This makes the Dissent BR4 particularly effective for long-range target shooting and hunting applications where precision matters. The rifle maintains reliable function across temperature extremes while the Cerakote finish resists wear from frequent handling and adverse conditions.
