The DISSENT Br4 utilizes CMMG's patented bufferless receiver and is designed for use with traditional rifle style stocks. The Dissent uses the company's patented Compact Action system, allowing for reliable direct impingement operation without the need for a buffer tube assembly. The DISSENT Br4 comes with a Magpul SGA stock for 870 shotguns. 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 features a 16.1-inch barrel along with an Armor Black Cerakote finish. One 10-round magazine is included.
