I also bought one used and am suffering from the same problem, I believe, in addition to the adjusting pads being too much filed to adjust in my chamber. Mine is also a 10 inch einstecklauf. It fit into my drilling quite easily and once solid shot quite well for my purposes, squirrels at about 25 yards, but I couldn't get it adjusted even remotely close to the sights. I'm anxious to see your results Steve.
