Pistol, DISSENT, Mk4, 5.56MM, 14.5" P&W
Short enough to be useful as a bufferless pistol, adaptable enough to be a rifle without SBRing thanks to the 14.5" barrel that's pinned and welded to 16.1". Chambered in 5.56x45mm, this DISSENT® pistol brings the compact size of a P&W 14.5" carbine together with the intuitive and smooth shooting bufferless Compact Action.
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.
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.
