Dirty Bird 8.6 BLK 300GR HPBT Subsonic Reman Ammo Rifle Ammo - 20 Rounds

Dirty Bird has developed a superb 8.6 Blackout cartridge using once-fired brass, Sierra Match King 300Gr projectiles. These are subsonic rounds with a muzzle velocity of 1007 FPS as measured using a 16" barrel. These rounds will also cycle in properly ported AR10 barrels using a standard AR10/SR-308 buffer system. Our brass is formed in a way that ensures you'll be able to reload these several times with minimal re-sizing required.
