About the 8.6 Blackout cartridge

8.6 Blackout is a .338-caliber cartridge from the creator of 300 Blackout, built to deliver heavy, hard-hitting subsonic performance from the AR-10 platform. It uses a shortened 6.5 Creedmoor case and a fast 1:3 twist that stabilizes heavy subsonic bullets, so they hit far above their modest velocity.

That blend of quiet and power is why 8.6 Blackout has earned such a following for suppressed hunting, and why this 8.6 Blackout GF-10 Complete Upper is built to perform on the platform the cartridge was designed for.
