The CMMG Dissent Mk4 is a direct-impingement semi-automatic rifle chambered in 6mm ARC. It has a 16.1-inch barrel made from 416 stainless steel with a 1:7.5 twist rate, weighs 6.4 lbs, and ships with two 10-round magazines. Finish is black.

The direct-impingement operating system keeps the design familiar for AR-platform shooters while the adjustable gas block lets you dial in the gas system for different loads. The CMMG ZEROED muzzle brake reduces felt recoil and helps with faster follow-up shots. The 416 stainless barrel handles heat well and the 1:7.5 twist stabilizes the 6mm ARC projectile across a range of bullet weights.
A reversible side-charging handle is included, which some shooters prefer over a standard T-handle for certain shooting positions or suppressor setups. The CMMG ZEROED pistol grip is comfortable and provides solid control without being unusually large or small.
The 6mm ARC cartridge delivers good long-range performance from a 16-inch platform, making this rifle a reasonable choice for precision-oriented range work or hunting where the caliber is appropriate. At 6.4 lbs it is light enough to carry comfortably in the field. Two magazines included out of the box is a practical touch.
The CMMG Dissent Mk4 in 6mm ARC generates genuine interest in the precision rifle community, and the feedback reflects that.
The 6mm ARC caliber is the most-discussed feature. Shooters who have worked with it note solid accuracy and effective range, better than 5.56 at distance without stepping up to a magnum cartridge. The build quality gets consistent praise: the rifle feels solid and the components fit tightly. Ergonomics are generally well-regarded, with the side-charging handle and adjustable stock mentioned as practical additions.
Price is the main point of friction. Some buyers see the cost as fair for the features and caliber; others feel CMMG charges a premium compared to AR-platform competitors with similar specs. Customization is an active topic. Owners discuss optics choices, barrel upgrades, and accessories, which speaks to the platform's flexibility.
Reliability is broadly positive, though a small number of owners have reported ammunition sensitivity or minor cycling issues under specific conditions. Most of those accounts note the problems were resolved through maintenance or ammunition selection rather than any persistent fault.
Overall reception is positive, with the 6mm ARC chambering being the primary draw for shooters who want more long-range capability from a standard AR-pattern rifle.
