| From my understanding if the barrel is machined correctly it can fit both the Tac 8 and Tac 9, the 9 barrel needs to rotate to allow the hopper feed orientation. I know End Game is offering barrels for both markers and the bore runs .689. I also just found out recently that Hammerhead is making a barrel for the Tac 8, no fins, but didn't' see anything about one for the Tac9, again bore size is .689. |
