Pistol, DISSENT, Mk4, 300BLK, 10.5"
Some cartridges require longer barrels to realize their full ballistic capabilities, but not 300 Blackout. Outfitted with a 10.5” barrel, this DISSENT® takes full advantage of almost any 300BLK loading you can think of while remaining ultra-compact and portable by eliminating the buffer system found on a conventional AR15. At the rear is a 1913 picatinny rail end plate allowing shooters to pick a folding pistol brace or stock* that suits their needs and style. Multiple Cerakote finishes ensures your DISSENT will always stand above the crowd.
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.
