The CMMG Dissent Mk4 (CMMG part no. 94AD10FAB) stretches the Dissent platform’s 9mm chambering out to a 10.5-inch barrel, giving shooters more velocity without giving up the compact, buffer-tube-free design that defines the line. A standard AR15 magwell runs CMMG 9 AR Conversion magazines, while the upper receiver houses the entire recoil system, eliminating the need for a conventional AR buffer altogether. Manipulating the bolt is as simple as reaching forward and pulling the non-reciprocating charging handle to the rear, allowing full operation while staying on target. Finished in CMMG‘s armor black, this longer-barreled Dissent balances portability with a bit more reach.
