One thing that has always set the AR15 platform apart from many of its rivals has been modularity. With the 9mm DISSENT available in the Mk4 platform shooters have a 9mm pistol that can use the CMMG 9 AR Conversion magazines. These magazines feature the same profile as 5.56mm magazines for a familiar manual of arms and true double stack feeding from top to bottom for fast and easy loading. - Each DISSENT comes in a range of Cerakote finishes. The M-LOK handguard allows for sleek accessory mounting to complement your DISSENT while the 1913 picatinny rail end plate allows for the attachment of slings pistol braces or stocks*. Bolt operation is accomplished via the forward non-reciprocating side charger allowing for quick use while staying on target. - Platform: Mk4 - Caliber: 9mm - Operating System: Compact Action-Radial Delayed Blowback - Barrel Length: 6.5 - Barrel Twist: 1:10 - Barrel Contour: MT - Barrel Material: 4140CM SBN - Barrel Twist: 1:10 - Muzzle Device: CMMG ZEROED Linear Compensator - Muzzle Thread: 1/2 x 28 - Upper Receiver: DISSENT 9mm 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: (2) CMMG 30rd - Weight: 4.6 lbs - Length: 14.7
