The CMMG 33A380C-AB Dissent MK3 .300 Blackout 12.5" rifle is purpose-built for close-quarters operations, home defense, and specialized tactical applications where hearing safety and target precision matter equally. Chambered in .300 Blackout—a cartridge engineered for subsonic performance—this platform delivers consistent, controllable ballistics in tight environments without the need for hearing protection.
The 12.5-inch barrel balances velocity retention with maneuverability, making it ideal for operators working in confined spaces, vehicles, or structures where a full-length rifle becomes a liability. The Dissent MK3 platform features a flat-top receiver configuration compatible with standard Picatinny rails for optic and accessory mounting, allowing you to customize the rifle for your specific mission profile.
Law enforcement tactical teams, military designated marksmen, and experienced civilians prioritizing low-noise, high-reliability platforms will find the CMMG 33A380C-AB Dissent MK3 .300 Blackout rifle fully compatible with standard AR-platform accessories and ammunition. The 20-round magazine capacity provides adequate ammunition on-target without requiring frequent reloads, critical in time-sensitive scenarios where magazine changes create tactical delays.
