CMMG's DISSENT Series is a New Step Forward in AR-Style Pistol Design

CMMG has a long history of designing and building AR-15 rifles to fit a wide variety of needs. Now, CMMG is proud to introduce something a bit different. The DISSENT is a personal defense weapon (PDW) that utilizes a unique compact action working in tandem with a direct impingement system. This eliminates the need for a buffer system, which means the DISSENT is radically shorter than other AR-style pistols on the market. With this compact action and recoil system comes a forward mounted non-reciprocating side charging handle which can be switched to the left or right side. A 1913 Picatinny rail end cap allows the user to add a compatible pistol brace if they choose, or a stock if the user chooses to go the SBR route (all NFA rules apply). The DISSENT also includes TriggerTech's AR-D trigger which was developed in collaboration with CMMG to be fully optimized for use with DISSENT firearms and upper receiver groups. If you're looking for an AR-style pistol that's ultra-compact without sacrificing firepower, the DISSENT may be exactly what you've been searching for!
