I got this Chinese SKS I'm trying to install a Tapco stock, pistol grip and handguard on. Everything on this piece is tight as a drum. I had to use a mallet to tap up the receiver cover release...it should be loose enough to use your finger. Anyway I've just about got it done except for the handguard. If you know the SKS you know the plastic handguard is held onto the gas tube frame by a pin at one end. You have to knock it out to remove the guard. I can't get this pin to budge. Ive dinged it up a bit from trying to punch it out. It almost seems like they mushroomed both ends of the pin so it couldn't be removed. Has anyone else had experience with these that might have a tip for me...as it is I'm stuck and out of ideas. I'd hate to have to try to find a replacement...I think they are matched to the piece on assembly. Will really appreciate any help.
