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. The 9mm version of the Dissent features a standard AR-style configuration with CMMG's signature radial delayed blowback action and makes use of CMMG's AR-style 9mm magazines, allowing for universal compatibility with existing AR-15 magazine pouches and equipment while retaining the familiarity of the AR platform. This model features a custom "Midnight Bronze" cerakote finish and includes two 30-round AR-style magazines.
