Hi! I've got an old Gem rifle that used to be the black and nickel version a very long time ago I believe. I've doing all kinds of strange fixes on it for a friend/customer but now it has a cocking problem as in it won't cock, the sear must be worn and need some possible filing and adjustment but I can't get it out of the body. I've ground down the flattened pin heads very carefully with a Dremell on both sides now but they just won't budge. I don't have a press so I've only been using a mallet and pin drift but I'm starting to wonder if there's something else going on here that I might have missed or not seen before. I remember you guys very kindly helped me out with information on this rifle before so I was hoping you could please help me again as I promised this guy I'd get it back to him this week, now I'm stuck or rather the pins seem to be. Cheers!
