FAQ

Can 300 Blackout ammo be mixed up with 5.56?

Keep them separate. A 300 BLK round can chamber in a 5.56 rifle and firing it can destroy the gun, so mark your 300 BLK magazines and uppers clearly.

Is a bolt carrier group included?

No. Add a standard AR-15/5.56 bolt carrier group; it is available as an add-on on this page.

What twist rate does the barrel use?

A 1:7 twist, which stabilizes both heavy subsonic and lighter supersonic 300 Blackout loads.
