Description

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.
