Challenge convention the CMMG DISSENT in 5.7x28mm is here to change the way you look at Personal Defense Weapons. One of the biggest challenges AR15 platform PDWs face is the buffer tube a necessity that always adds to the overall footprint until now. The DISSENT eliminates the need entirely by employing our patent-pending Compact Action that also works hand in hand with our renowned Radial Delayed Blowback operating system. - In addition to containing the entire action and recoil system in a more compact package every DISSENT features a forward non-reciprocating side charger interchangeable from left to right allowing shooters to charge the weapon while staying focused on target. - Every DISSENT comes with a 5 M-LOK handguard and a 1913 picatinny rail at the rear to attach the pistol brace or stock of your choice so you can make the DISSENT fit you. - TriggerTech AR-D 2-Stage Trigger - TriggerTech's AR-D trigger was developed in collaboration with CMMG to be fully optimized for use with DISSENT firearms and upper receiver groups. With a 4 lb pull weight the AR-D trigger showcases a light repeatable break. CMMG does not guarantee optimal DISSENT functionality with Mil-spec or other aftermarket triggers. - Platform: Mk4 - Caliber: 5.7x28mm - Operating System: Compact Action-Radial Delayed Blowback - Barrel Length: 6.5 - Barrel Twist: 1:9 - Barrel Contour: MT - Barrel Material: 4140CM SBN - Barrel Twist: 1:9 - Muzzle Device: CMMG ZEROED Linear Compensator - Muzzle Thread: 1/2 x 28 - Upper Receiver: DISSENT 7075 T6 Aluminum - Lower Receiver: Mk4 Forged 7075 T6 Aluminum - Hand Guard: CMMG 5.5 Proprietary - Finish: Cerakote - Charging Handle: DISSENT Side Charger Left - Pistol Grip: CMMG ZEROED Pistol Grip - Receiver Extension: 1913 Picatinny Rail End Cap - Trigger Type: TriggerTech AR-D 2-Stage - Trigger Guard: CMMG ZEROED Trigger Guard - Safety Selector: CMMG ZEROED 60/90 Degree - Magazine: CMMG 32rd - Weight: 4.6 lbs - Length: 14.7
