CMMG Dissent BR4 6.5 Grendel CA Compliant 16.1" 10+1 Rifle

The CMMG Dissent BR4 delivers precision shooting capability in a California-compliant configuration, chambered in the versatile 6.5 Grendel cartridge. This rifle combines CMMG's innovative design with compliance features that maintain functionality while meeting restrictive state regulations.

What Makes This Different

The Dissent platform represents CMMG's departure from traditional AR-15 architecture, featuring a proprietary action that cycles more smoothly than standard direct impingement systems. The 6.5 Grendel chambering provides superior ballistic performance compared to 5.56 NATO, delivering flatter trajectories and increased energy retention at extended ranges. California compliance features include a fixed magazine configuration and compliant grip, allowing legal ownership without sacrificing core functionality.

Key Features

• 6.5 Grendel chambering for enhanced long-range performance and energy retention
• 16.1-inch barrel with Black Armor Cerakote finish for corrosion resistance
• Aluminum receiver construction with precision machining tolerances
• Magpul SGA stock providing adjustable length of pull and cheek weld
• Zeroed drop-in single-stage trigger for consistent, crisp break
• California-compliant configuration with fixed magazine system
• 10+1 capacity meets state restrictions while maintaining tactical capability

The 6.5 Grendel cartridge excels in hunting applications for medium game at ranges exceeding 300 yards, where 5.56 NATO begins to lose effectiveness. Competition shooters benefit from reduced wind drift and consistent accuracy potential. The Cerakote finish withstands harsh environmental conditions while the aluminum construction maintains durability without excessive weight. The single-stage trigger provides predictable break characteristics essential for precision shooting disciplines.
