Keeping Traditions Alive Since 1953

The 6mm ARC has quietly become one of the most interesting cartridges to hit the AR world in years, and the CMMG Dissent BR4 is one of the smarter ways to run it. You get ballistics that hang with much bigger rounds out past 600 yards, but from a rifle that handles like a lightweight carbine and recoils like a soft-shooting .223. CMMG pairs that with their Compact Action direct impingement system, which trims down the operating group without giving up the reliability the platform is known for.
Instead of a traditional rear charging handle and buffer tube, the Dissent uses a reversible side charger, so you can rack it with either hand and keep your optic mounted low without fighting for clearance. The lower is billet 7075-T6 aluminum with an integrated trigger guard, and the whole rifle wears a durable black Cerakote finish. Controls stay simple and familiar with a reversible crossbolt safety, and the Magpul SGA stock gives it a solid, traditional cheek weld that a lot of hunters end up preferring over a collapsible setup anyway.
The 16.1 inch medium taper barrel is 4140CM steel with a salt bath nitride treatment for corrosion resistance and long service life. The fast 1:7.5 twist stabilizes the heavy, high-BC 6mm bullets this cartridge was built around, and the 5/8×24 threaded muzzle comes topped with CMMG's ZEROED muzzle brake. If you plan to run a suppressor or want to tune cycling to a specific load, the adjustable gas block lets you dial the system in rather than living with an overgassed gun.
The ZEROED drop-in single stage trigger breaks clean enough for precision work off a bag, and at 8 pounds with a 38.1 inch overall length, the rifle carries comfortably in the field. Two CMMG 10-round magazines ship with it, and CMMG stands behind the gun with their Lifetime Quality Guarantee. Whitetail, coyotes, or long steel, this one covers a lot of ground with a single rifle.
The 6mm ARC splits the difference in a really useful way. It delivers extended range ballistics that rival bigger .308-class rounds, but from a compact rifle with noticeably less recoil than a large-frame gun. For long steel sessions or medium game hunting, it stays supersonic further and drifts less in the wind than 5.56.
No, it ships optics-ready with no sights installed. The full-length Picatinny top rail handles everything from red dots to magnified scopes, and the side charging handle keeps the rear of the receiver clear so mounting an optic is simple. Given the reach of 6mm ARC, most owners put a variable power scope on this rifle.
Yes, the muzzle is threaded 5/8×24, so removing the included ZEROED brake and attaching a suppressor or mount is straightforward. Even better, the adjustable gas block lets you turn the gas down when shooting suppressed, which cuts back on gas blowback and keeps the rifle cycling smoothly.
The Dissent side charger is reversible, so you can set it up on the left or right side of the receiver depending on your preference. It replaces the traditional rear AR charging handle entirely, which makes charging the rifle easier with a large scope mounted and works well for left-handed users.
