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 ZEROED Drop-In Single Stage – Trigger Guard CMMG ZEROED Trigger Guard – Safety Selector CMMG ZEROED 60/90 Degree – Magazine (2) CMMG 30rd – Weight 4.6 lbs – Length 15.7
