After getting the hinge pin pivot honed to the correct position so that the barrel fit the receiver correctly I went to work to get the latch engagement to the specified 1/8 inch. I can tell you now with no doubt that .125 inch specified is too much latch engagement. This amount put the latch at the end of it's travel on a SB2 receiver. When I look at the engagement on a proper fitting factory barrel it is about .075 to .080 inch, which leaves some latch travel and provides a good lock up. OK, A nice lesson, (a little pricy) but I will start over, Just be careful with following the instructions and watch how much travel you have left in the latch release while you are doing the barrel fitting.
