I was hoping someone could help me out. I just traded for a M63 4" kit gun and wanted to install a rear sight slide with a white outline. The stock replacement is a .086. I looked the usual places (Brownells, Midway, Numrich), but cannot find either .086 or .101 slides in stock with the white outline. The .086 would be my first choice, but I think I could get by with a .101. Any help would be appreciated. Thanks, Swabby.
