CMMG 30A750A-MB DISSENT MK4 300BO 16.1 MDBRZ

The CMMG DISSENT MK4 300 Blackout with 16.1-inch barrel and muzzle brake is a modern intermediate rifle engineered for mission-critical versatility. The 300 Blackout cartridge delivers effective performance across subsonic and supersonic loads, making this platform ideal for operators who require a single rifle capable of suppressed and unsuppressed configurations without caliber changes. The 16.1-inch barrel length balances muzzle velocity with maneuverability, critical for close-quarters scenarios, CQB training, and transitional environments where carbine-length ergonomics are essential.

Built on the proven AR-15 platform, the DISSENT MK4 maintains the modularity and accessory compatibility that professional end-users demand. The muzzle brake configuration reduces recoil impulse and manages recoil climb during rapid strings, improving target reacquisition time compared to open-muzzle configurations. At 10.2 pounds, the rifle remains portable for extended operations while maintaining sufficient mass for controlled shooting. The medium bronze finish offers durability against environmental exposure while maintaining a professional tactical appearance suitable for duty or training environments.

This rifle addresses shooters who operate in roles requiring precision within 300-yard engagement envelopes, including law enforcement special operations, private security, precision rifle training, and hunters pursuing medium game where the 300 Blackout's performance envelope applies. The CMMG DISSENT MK4 300BLK appeals to operators already familiar with AR ergonomics who seek a dedicated intermediate platform without the commitment to alternative caliber ecosystems. The 300 Blackout market has matured significantly, with ammunition and suppressor compatibility now a mature infrastructure for serious practitioners.
