The hole in the gas block was about the same size as the supplied drill bit, it wasn't a sloppy fit at all but the drill bit slid in so no drilling required (large hole gas block?). There was no tap in my kit, the instructions were to drill the hole then thread the insert into the hole (insert maybe intended to thread as it went?). I did that, it got pushed up into the gas tube by about 14000lbs of pressure(ish) shutting off the gas to the BCG. Like I said, Clint took care of me, but I think the hole that takes the threaded insert should be properly threaded for the insert and it probably needs a shoulder of some sort to seat so it can't move.
