CMMG Dissent BR4 9mm CA Compliant 16.1" Coyote Tan 10+1 Capacity

The CMMG Dissent BR4 delivers reliable 9mm performance in a California-compliant configuration that doesn't compromise on functionality. This straight-blowback carbine combines CMMG's proven engineering with features specifically designed for restrictive state regulations while maintaining the reliability shooters expect from professional-grade firearms.

What Makes This Different

Unlike traditional AR-15 platforms, the Dissent BR4 utilizes CMMG's straight-blowback operating system specifically engineered for pistol calibers. The 16.1-inch barrel provides optimal velocity for 9mm ammunition while meeting rifle length requirements. The Coyote Tan Cerakote finish offers superior corrosion resistance compared to standard phosphate coatings, rated for 1,200+ hours of salt spray testing.

Key Features

• California-compliant configuration with fixed stock and 10-round magazine capacity
• 16.1-inch barrel with 1:10 twist rate optimized for 115-147 grain 9mm ammunition
• Coyote Tan Cerakote finish on aluminum receiver for enhanced durability
• Magpul SGA stock provides consistent cheek weld and length of pull
• Zeroed drop-in single-stage trigger with crisp 4.5-6 pound pull weight
• Standard AR-15 controls and ergonomics for familiar operation
• Accepts Glock-pattern magazines for widespread compatibility

The straight-blowback action eliminates gas system complexity while providing consistent cycling across various ammunition weights. Range testing demonstrates reliable function with both 115-grain FMJ and 147-grain subsonic loads. The extended barrel length maximizes 9mm ballistic potential, delivering approximately 100-150 fps velocity increase over shorter carbines. Weather sealing at critical junctions maintains function in adverse conditions.
