The CMMG DISSENT MK4 in 300 Blackout is engineered to leverage the ballistic capabilities of the 300BLK cartridge within a compact and highly portable platform. This design precisely integrates CMMG’s proprietary DISSENT bufferless operating system, thereby eliminating the traditional AR-15 buffer tube and significantly reducing the overall length of the firearm.
Key Features
Bufferless Operating System & Compact Form Factor
The DISSENT system reconfigures the recoil mechanism to operate entirely within the upper receiver, removing the necessity for an external AR-15 buffer tube. This innovation not only facilitates enhanced portability but also supports diverse configurability options for the end-user. The 10.5-inch barrel length is specifically chosen to optimize 300BLK performance while maintaining a maneuverable profile, ideal for close-quarters applications and transport.
Integrated 1913 Picatinny Interface
A robust 1913 Picatinny rail end plate is integrated at the rear of the receiver. This interface allows for the secure attachment of various firearm accessories, including folding pistol braces or stocks, enabling users to tailor their setup for specific operational requirements.
Adjustable Gas System
This platform includes a factory-installed adjustable gas block, providing critical functionality for precise tuning. Users can optimize gas flow to ensure consistent and reliable cycling across a spectrum of 300 Blackout ammunition types, including supersonic and subsonic loads. This adjustability is particularly beneficial for mitigating recoil impulse and ensuring optimal performance when operating with a sound suppressor.
Optimized Trigger System
Equipped with a TriggerTech AR-D trigger, developed through direct collaboration with CMMG, this system provides a consistent 4 lb pull weight with a clean, repeatable break. This optimized trigger is essential for reliable function within the DISSENT platform; CMMG specifies that using Mil-spec or other aftermarket triggers is not advised to maintain system integrity and performance.
Advanced Finish Options
The DISSENT MK4 is available with multiple durable Cerakote finish options, providing enhanced corrosion resistance and wear mitigation while allowing for user preference in aesthetics.
