Thanks to all of you who responded. I have borrowed a bit from all of your recommendations. Now using an oak dowel as well as a brass punch. Also purchased some small files (flat, triangular,etc) and did some light filing on the stake marks. I can now push the sight about 90% of the way back to the felt where I want to end up. The last 10 % seems to be "a bridge too far", and I'm afraid I might damage the receiver or sight if I hit it too hard. I can live with it the way it is, and after a few days will probably send off to purchase the rear sight installation and removal tool from Fulton Armory. I should have just bought it in the beginning, but then I would have had to find another way to fill up 4 or 5 days. We live and learn I guess. Thanks again for your help. I will submit a few pictures when I get this resolved....JKL
