The CMMG DISSENT MK4 300 Blackout AR Pistol is engineered for compact performance without compromising ballistic utility. This platform leverages the inherent efficiency of the 300 Blackout cartridge, delivering full performance from its 10.5-inch barrel while maintaining a significantly reduced footprint. The DISSENT MK4 eliminates the conventional AR-15 buffer system, streamlining its design for enhanced portability and integration into diverse operational profiles.
Key Features
Buffer-less Compact Design
The DISSENT MK4 system integrates a proprietary operating mechanism that removes the need for an external buffer tube, directly contributing to its ultra-compact form factor. This design facilitates efficient maneuverability and storage without degrading the operational reliability characteristic of CMMG platforms. The 10.5-inch barrel length is specifically optimized to maximize the ballistic potential of 300 Blackout loadings across a wide spectrum of bullet weights and velocities.
Caliber Optimization & Gas Management
The 300 Blackout cartridge offers substantial versatility, excelling in both supersonic and suppressed subsonic configurations. The DISSENT MK4 addresses this with an integrated adjustable gas block, enabling precise regulation of the gas system. This critical feature allows shooters to fine-tune the platform’s cycling for optimal performance with specific ammunition types, ensuring consistent function whether utilizing high-velocity hunting loads or specialized subsonic rounds.
Precision Fire Control
Developed in direct collaboration with CMMG, the included TriggerTech AR-D trigger is optimized for the DISSENT operating system. This two-stage trigger unit provides a crisp, repeatable break at a pull weight of 4 pounds. Its design prioritizes consistent tactile feedback and reduced reset for precise shot placement, a critical attribute for competitive and tactical applications.
Modular Rear Interface
Equipped with a 1913 Picatinny rail end plate, the DISSENT MK4 offers a robust and adaptable interface for a broad range of stock, brace, or sling mounting solutions. This design decision provides the end-user with maximum flexibility to configure the platform to individual preferences and mission requirements.
