Tony, I'm in the same boat you are. I bought one of the 264 LBC BHW barrels from New Frontier too. I called BHW and was told that in May, their supplier of barrel extensions changed to Type II without telling them. The headspacing is different between Type I and II. I spoke with Andy at BHW and gave him my serial number. He said that my barrel could be either type since it was manufactured about the time of the switch. He is supposed to be sending me both bolt types in the mail so I can test-fit them and determine which bolt I need. I'd call Andy at BHW and get put on the waiting list to receive both bolts so you can check to make sure.
