Pistol, DISSENT, Mk4, 300BLK, 6.5"
The CMMG® DISSENT™ is an AR Personal Defense Weapon like no other. Incorporating a variety of new features and technologies, each DISSENT is made to maximize portability and modularity, most notably thanks to CMMG®’s patent-pending Compact Action that houses the entire recoil system in the upper receiver, eliminating the need for the buffer tube altogether.
Chambered in 300 BLK, this DISSENT packs .30 cal power in an ultra-compact package that offers AR15 ambi controls and our forward non-reciprocating side charger that can be switched for left or right-handed operation. At the rear of the lower receiver is a 1913 picatinny rail section for attaching the brace or stock* that fits you best.
Each DISSENT is available in a variety of custom Cerakote finishes to match your style.
300 BLK is an incredibly adaptable cartridge with different loadings for specific uses, like suppressed. With the SLR adjustable gas block on each 300 BLK DISSENT you can fine tune the gas system to best suit the supersonic or subsonic ammo loadings you like best.
TriggerTech’s AR-D trigger was developed in collaboration with CMMG to be fully optimized for use with DISSENT firearms and upper receiver groups. With a 4 lb pull weight, the AR-D trigger showcases a light, repeatable break. CMMG does not guarantee optimal DISSENT functionality with Mil-spec or other aftermarket triggers.
We aim to please, that’s why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects. Learn More.
*NFA Rules May Apply
Each DISSENT is shipped in pistol configuration, adding a stock will make your DISSENT an SBR and subject to NFA rules. Learn more about NFA rules.
