When I was at my parents recently I brought home the first gun I was ever given, a Remington Nylon 66 that dad bought for me when I was 3. It has a bit of surface rust which I am cleaning up as it was not stored in the most ideal conditions over the years. The problem I ran into is the elevation screw for the rear sight and the little washer that hold it in place have gone missing. I have searched several places online and no one has them. Anyone have a good source for these or can maybe point me in the right direction?
