CMMG Dissent BR4 6mm ARC 16.1" 10+1 Semi-Auto Rifle - CA Compliant

The CMMG Dissent BR4 is a semi-auto rifle chambered in 6mm ARC, built around a 16.10" threaded barrel paired to a 7075 aluminum receiver finished in Armor Black Cerakote with an integrated Picatinny rail. This *CA Compliant configuration ships with a 10+1 capacity and wears a Magpul SGA black synthetic stock in the Remington 870 pattern.

The 6mm ARC (Advanced Rifle Cartridge) was developed to deliver extended-range ballistics from the AR-15 platform with mild recoil, making the Dissent BR4 well-suited to hunting and precision target work. The barrel features a 1:7.50" twist and a black nitride finish, and is threaded for the CMMG Zeroed muzzle brake. Controls include a crossbolt safety and the Zeroed single-stage trigger; the rifle ships without iron sights so the shooter can mount their preferred optic directly to the top Picatinny rail. Overall length is 38.10" and the rifle weighs 8 lbs.

Two 10-round magazines are included to support *CA Compliant ownership, and the optic-ready platform lets the buyer pair the rifle with their preferred red dot, prism, or low-power variable optic.
