Pistol, DISSENT, Mk3, 8.6 BLK, 12.5"
The larger younger brother to 300 BLK, 8.6 BLK builds on the lessons and successes of its 30 cal counterpart and brings them to the AR10-sized DISSENT Mk3 platform. Equipped with a quick 1:3 barrel twist, 8.6 BLK performs exceptionally out of shorter barrels and suppresses every bit as well as 300 BLK with the bigger and beefier .338 caliber projectiles.
Available in seven Cerakote finish options, this DISSENT Mk3 pistol comes either as a bare pistol with a 1913 picatinny rear plate, to easily attach your own accessories like slings and braces, or as a pistol with an SB Tactical FS1913A aluminum folding brace.
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.
