Product Description:
The Dissent Mk4 features a bufferless receiver designed for use with folding stocks and braces, along with intermediate cartridges like the popular 5.56x45mm NATO. It utilizes CMMG’s patented Compact Action system for reliable direct impingement operation without the need for a buffer tube assembly. The Dissent also features a side charging handle forward of the action, making manipulation easier.
New for 2025, the Dissent now comes in Hornady’s .338 ARC cartridge, combining the AR15 platform with the stopping power of a large bore caliber. This model includes a Z-series muzzle brake and CMMG’s proprietary MLOK handguard. It comes in a rifle configuration with a 16.1-inch barrel and Sniper Grey Cerakote finish, as well as a 10-round magazine included.
