Black Hole Weaponry, 6x6.8 AR15 barrel 22" SS,
P3 grooved, 1/10" twist, 5/8x24 threaded. Exactly 289 rounds through it. Super clean & shooting.
It takes a .750" gas block, rifle length gas system, I can add the bolt head for $80. (NOT the complete BCG)
Barrel ONLY......$300 shipped to your door.
Barrel with the 6.8 bolt head.....$380 to your door.

Picture for looks only if you want to see what it looks like as an upper.

Barrel only? No bolt?

Length of gas system?

Size of gas block needed? (barrel shank size at gas block)
