The CMMG Dissent Mk17 (CMMG part no. 92A682CAB) brings cross-platform compatibility to CMMG’s buffer-tube-free Dissent line, running Sig Sauer P320 9mm magazines so shooters can swap seamlessly between a full-size pistol and a compact PDW without buying into a new proprietary magazine system. A 6.5-inch barrel keeps the package tight, and the pistol ships with two 21-round P320 magazines ready to load. A 1913 Picatinny rail end plate at the rear of the lower receiver lets you attach the brace of your choice, and bolt operation runs through a forward non-reciprocating side charger that keeps you on target while cycling the action. Finished in black by CMMG, this Mk17 Dissent is one of the most portable 9mm PDWs on the market.
