Pistol, DISSENT, Mk4, 9MM, 16.1"
If there were one word used to describe a Mk4 DISSENT®, adaptable would have to be it. Chambered in 9mm with a 16.1" barrel, this DISSENT utilizes our 9mm AR Conversion Magazines that feature the same profile and dimensions as a standard 5.56mm PMAG. Not only does this allow for easy use with existing mag pouches, but the Mk4 DISSENT lower also makes for a seamless transition to virtually every other DISSENT caliber offering, when paired with a matching caliber magazine.
Hosting an array of ZEROED parts and accessories, the Mk4 DISSENT builds on the renowned AR15 manual of arms. One main exception is the forward non-reciprocating sider charger. This allows the shooter to configure the DISSENT with either a left or ride-side charging handle that can be manipulated while aiming downrange. The patent pending Compact Action removes the need for an AR buffer system and replaces it with a 1913 Picatinny rail end plate, perfect for attaching a variety of accessories including slings, folding stocks, and pistol braces.
Each DISSENT is available in a range of Cerakote finish options ensuring that the DISSENT matches your style and not just any style.

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.
