Pistol, DISSENT, Mk4, 300BLK, 16.1"
One size fits all usually means something that does many things okay at best, 300BLK challenges that notion. With subsonic and supersonic loadings available for self-defense, hunting, and target shooting, 300BLK is one of the most user-friendly cartridges out there today. A round this capable needs a firearm to match though, and this CMMG® DISSENT® with a 16.1" barrel leaves no performance behind while remaining an incredibly stable and modular platform.
Shipped as a pistol with no rear furniture, the DISSENT eliminates the buffer tube recoil system replacing it with our patent-pending Compact Action which houses the entire action in the upper receiver. If you do prefer to add an accessory like a sling or folding stock, the rear of the lower receiver features a 1913 Picatinny rail end plate ready to outfit how you see fit. Seven Cerakote finish options gives your DISSENT a stylish, personalized look.
Adjustable Gas Block
300 BLK is an incredibly adaptable cartridge with different loadings for specific uses, like suppressed. With the 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.
