CMMG Dissent BR3 308 Win 16.10" Barrel 10+1 Tungsten Cerakote

The CMMG Dissent BR3 represents a significant advancement in AR-10 platform engineering, delivering precision .308 Winchester performance in a compact, reliable package. This straight-pull bolt-action rifle eliminates the complexity of gas systems while maintaining the familiar AR ergonomics shooters demand.

What Makes This Different

Unlike traditional semi-automatic AR-10s, the Dissent BR3 utilizes CMMG's proven straight-pull bolt system that requires no gas block, gas tube, or buffer system. This design reduces moving parts by 40% compared to standard AR-10 rifles, resulting in increased reliability and simplified maintenance. The medium taper barrel profile provides optimal balance between accuracy and maneuverability.

Key Features

• Straight-pull bolt-action system eliminates gas system complexity and potential failure points
• 16.10-inch medium taper barrel with black nitride finish for enhanced durability and corrosion resistance
• Tungsten Cerakote aluminum receiver provides superior wear resistance and distinctive appearance
• M-LOK compatible handguard offers multiple attachment points for accessories and optics
• Magpul SGA synthetic stock delivers adjustable length of pull and cheek riser compatibility
• Threaded barrel accepts standard 5/8x24 muzzle devices and suppressors
• 10+1 capacity with standard SR-25 pattern magazines

The Dissent BR3 excels in precision shooting applications where reliability takes priority over rapid follow-up shots. The straight-pull action cycles smoothly under adverse conditions that might cause gas-operated systems to malfunction. Hunters appreciate the reduced noise signature and elimination of gas blowback when using suppressors. Competition shooters benefit from the consistent bolt closure and enhanced accuracy potential of the fixed barrel system.
