So, it's been two days now that I've been trying to get this rear sight block off. There were two grub screws that held the underside outer barrel, which I removed. But the problem is that the pin can't be removed for some reason. There is a pin that pinned the rear sight block and outerbarrel together. I honestly don't think the pin is glued anymore. I've blowtorched it, set it over the fire for ten minutes, tried to hammer the pin out with several tools, and it won't even bulge. So, anyone here with an LCT Ak74MN or similar experience knows how to take this thing off? I only need the pin out to move the rear sight forward so I can twist the outer barrel in to the receiver. The only thing I could think of is to drill press the pin out, and it's the last route I want to take.
