I really do not want to rebarrel the gun. at this point it isn't worth it. and honestly I think that if I would handload I would get better groups which is most likely going to happen. but that sight you have pictured was the one on the gun I have. I can tell because of the two mounting bolts it use. they might have even been pins that the sight was pressed onto. what is the name of it and do you have a person I can look into buying one? I was thinking about buying a williams peep sight and drilling the reciever to mount it. since making it orginal is out of the question obviously. thanks for the help.
