The CMMG 34A670FAB Dissent BR4 338 ARC pairs CMMG’s modern semi-automatic design with a purpose-built precision configuration. Built on a black armor Cerakote aluminum receiver with a full-length Picatinny rail, it uses a 16.10" chrome moly steel black nitride threaded barrel capped with a CMMG Zeroed muzzle brake and surrounded by a lightweight M-LOK handguard. A Magpul SGA 870 synthetic stock and reversible crossbolt safety round out a clean, ergonomic package.

This Dissent BR4 in 338 ARC is configured for shooters who want a capable rifle for range work, training, or hunting where accuracy and controllable recoil matter. The threaded 5/8"x24 barrel makes it ready for compatible suppressors or other muzzle devices, while the 10-round capacity keeps the profile compact and compliant in many jurisdictions. With its 37.50" overall length, 1:8" twist, and 7.90 lb weight, the rifle balances stability with maneuverability, reflecting CMMG’s focus on thoughtful engineering and consistent craftsmanship.
