CMMG Dissent Mk4 Pistol, .300 Blackout, 6.5-Inch, Coyote Tan

The CMMG Dissent Mk4 (CMMG part no. 30A0E33CT) is an AR personal-defense weapon like no other, chambered in .300 Blackout and built around CMMG’s patent-pending Compact Action. That system houses the entire recoil assembly inside the upper receiver, eliminating the need for a buffer tube entirely and dramatically shortening the pistol’s overall length. A 6.5-inch barrel packs full .30-caliber power into an ultra-compact package, and the forward non-reciprocating side charger can be configured for left- or right-handed operation. A Picatinny rail section at the rear of the lower receiver lets you attach the brace that fits your build. Finished in coyote tan by CMMG, this Dissent is built to maximize portability without sacrificing capability.
