I have a Winchester 1000x made in Turkey. I got the trigger partly apart; the rest is welded to the frame, and got the spring out but can't get what I think is the piston out. There's another tube or something moving back and forth in there and I can't get the cocking lever loose to get it out. I bought the gun at a pawn shop just to learn to work on so I'll try anything but would like it to shoot if possible.
