Pistol, DISSENT, Mk4, 5.56MM, 16.1"
The 16.1" DISSENT® chambered in 5.56mm brings rifle-esque performance packed into one of the most modular pistol platforms ever created. Featuring our patent-pending direct impingement Compact Action, the DISSENT houses the entire action and recoil system in the upper receiver, eliminating the need for the buffer system entirely.
Available in a variety of custom Cerakote finish options, the rear of the DISSENT features a 1913 Picatinny rail that’s accessory ready for attachments like slings, folding stocks, pistol braces, and more.
Adjustable Gas Block
If you’re looking to shoot suppressed or just fine tune your DISSENT to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking. Never too much and never too little.
