Pistol, DISSENT, Mk4, 9MM, 10.5"
Built on the Mk4 platform, this 10.5” 9mm DISSENT® is smaller in all the right places without compromising on user friendliness. A standard AR15 magwell allows for use of CMMG® 9 AR conversion magazines, while the upper receiver houses the entire action, completely eliminating the need for a conventional AR buffer system. Manipulating the bolt is as simple as reaching forward and pulling the forward non-reciprocating charging handle to the rear, allowing full operation while aiming downrange.
The rear 1913 picatinny rail end plate lets you customize your DISSENT with accessories like slings or stocks*, and 6 different Cerakote options provide a resilient yet eye catching finish.
Radial Delayed Blowback™ Compact Action
9mm ammo loadings can vary greatly, from supersonic to subsonic. With a wide range of bullet weights comes new engineering challenges in a new platform. The 9mm Radial Delayed Blowback Compact Action addresses these challenges by utilizing a fixed ejector in the upper receiver. Added benefits are a lighter BCG with less felt recoil while providing consistent performance with a wide range of ammo.
