I have heard that the thread is 20x1. I'm going to be working with John to get an adapter made so that I can fit a 1/2x20 moderator on the end of my gun. It's proving to be more difficult than I'd like.
TP3. That's exactly what I'm looking for. Was ordering but they want 23.00 for the freight to drop it in the mail. Seems kind of excessive. I'll try spinning up the lathe.
