I've got a real nice 57 99F that came with dovetail blank and a scope. I took the scope off and want to re-install the rear sight. This one is going to stay in the safe (have another for the stand).
I removed the forearm and have tried my darnest to get the blank out. I tried hitting hammer on a pine dowel and also using a chunk of birch I carved out. I tried soaking overnight with Kroil (no rust present ... just trying to get something that penetrates in there). It has not budged a millimeter.
Any tips on what I should try? This blank is really stubborn. The last thing I want to do is mess up the bluing.
