Pistol, DISSENT, Mk3, 8.6 BLK, 16.1"
Joining .308 Win and 6.5 Creedmoor in the DISSENT Mk3 lineup is the much anticipated 8.6 BLK, the large frame counterpart to 300 BLK. A fast barrel twist rate lets the 8.6 BLK DISSENT do with a 16.1" barrel what other rifles need 20"+ to do.
Available in pistol configuration for those who want options. The rear of this DISSENT features a 1913 Picatinny rail end plate that allows for the attachment of accessories like sling mounts, braces, and more. Thanks to the 16.1" barrel even folding stocks can be added without becoming an NFA item and having to register an SBR.
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.
