Shooting in close quarters or mid-range distances? The 14.5" DISSENT Pistol in 300 BLK has enough barrel to extract the full performance of 300 BLK without the extra unnecessary length. Want to add a folding stock to this? No problem the ZEROED SVD Brake pinned and welded to the 14.5" barrel brings the legal length up to 16.1" so you don't have to worry about SBRing anything.

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.
