I looked into my bolt but there was no peep nut. Maybe there was a bolt peep on your gun at some earlier time and it was removed but the nut was left as it is too hard to remove. Just a thought. Daryl

I have a reproduction bolt peep for an early model 71. I need to remove the bolt to mount the nut that raises the peep up and down and am not sure of how to do it. Anyone have the knowledge on how to do that or where online there could be a blowup of the model 71 and the bolt? Thanks.
