CMMG Dissent Mk4 5.56 NATO 10.5" 30-Round Threaded Barrel Pistol

The CMMG Dissent Mk4 5.56 NATO 10.5" 30-Round Threaded Barrel Pistol is purpose-built for operators who demand a compact, magazine-fed platform with serious capability in confined spaces. Whether deployed in breaching operations, vehicle defense, or close-quarters tactical scenarios, this pistol-configured AR delivers the modularity and firepower expected from professional-grade equipment. The short 10.5-inch barrel profile makes it ideal for law enforcement special response teams, military personnel, and civilian defenders operating in urban or transitional environments where full-length rifles prove unwieldy.

Built on the proven 5.56 NATO platform, the Dissent Mk4 features a threaded barrel that accepts industry-standard suppressors and muzzle devices, enabling rapid sound signature reduction or recoil management without permanent modification. The 30-round capacity maintains standard AR magazine compatibility, ensuring logistics simplicity and ammunition flexibility across mixed-platform deployments. At 8.44 pounds, the system strikes a balance between control and portability—light enough for sustained operation yet substantial enough to manage 5.56 recoil signature effectively. CMMG's Dissent line is engineered around direct-impingement reliability, delivering consistent performance across ammunition types and environmental conditions that tactical operators encounter.

This platform serves operators requiring both legal rifle ergonomics and the maneuverability of a pistol-length firearm without the complexity of caliber conversion. The threaded muzzle allows fast integration of suppressors, flash hiders, or compensators tailored to mission requirements—critical in team operations where acoustic signature impacts tactical advantage. Magazine-fed operation with standard 5.56 NATO rounds ensures predictable ballistics and barrier performance in real-world scenarios, while the compact form factor excels in vehicle interdiction, maritime operations, and structure-dependent tactical entries where clearance demands premium design choices.
