Owners of the CMMG Dissent MK4 in Charcoal Green frequently highlight the folding stock as the standout practical feature, making the rifle noticeably easier to store and transport compared to fixed-stock AR variants. The Charcoal Green Cerakote finish is generally well-received, with owners noting it holds up well through regular handling without visible wear.

The threaded barrel is appreciated by owners who want suppressor compatibility or the option to run a muzzle device, though the 10-round capacity is a recurring frustration in states where standard-capacity magazines are permitted. The .22 ARC chambering gets mixed reactions; enthusiasts value the ballistic performance, but sourcing ammunition locally can be a challenge.

CMMG's build quality on the Dissent MK4 is broadly viewed as consistent and above the average AR entry-level offering. Trigger feel is the most common point of debate, with some owners satisfied and others swapping it out early. Overall, the Dissent MK4 is regarded as a solid AR-pattern option for those specifically drawn to the .22 ARC cartridge and a folding-stock package.
