The Dissent Mk4 features bufferless receiver designed for use with folding stocks and braces along with intermediate cartridges like the popular 5.56x45mm NATO. The Dissent utilizes CMMG’s patented Compact Action system, allowing for reliable direct impingement operation without the need for a buffer tube assembly. The Dissent also sports side charging handle forward of the action, allowing for easier manipulation of the charging handle to chamber rounds or clear malfunctions. The charging handle is non-reciprocating to allow for use with modern shooting stances and is easily reversible to accommodate left-handed users.

New for 2025, CMMG is happy to introduce their tried and true platform in Hornady’s new .338 ARC cartridge. Made to combine the prowess of the AR15 platform with the stopping power of a large bore caliber, .338 ARC strives to emulate the sub or supersonic versatility of the now ubiquitous .300 BLK cartridge with more energy on target and less gas system tuning when switching from suppressed to unsuppressed. This model comes with a Z-series linear compensator and CMMG’s proprietary MLOK handguard.

This model comes in a pistol configuration and features a 10.5-inch barrel and an FS1913 folding brace along with an Titanium Cerakote finish. One 10-round magazine is included.
