The CMMG Dissent series establishes a benchmark for compact AR platforms. Utilizing CMMG’s patented Compact Action, these AR pistols eliminate the traditional buffer tube, resulting in an exceptionally short and stowable firearm. This design positions the Dissent .300 Blackout as an effective solution for personal defense, offering enhanced maneuverability in confined operational environments.
Chambered in .300 Blackout, this Dissent model integrates a 6.5-inch free-floated barrel, engineered to promote consistent accuracy across a diverse range of .300 Blackout loads, from supersonic to subsonic. The barrel is complemented by a 5.5-inch M-LOK handguard, facilitating the direct integration of tactical accessories. The receiver features a durable Black Cerakote finish, providing robust corrosion resistance and a non-reflective aesthetic.
