I disassembled a 597 Remington .22 Mag automatic to clean it. Their way to put it together isn't working. I was able to get one spring compressed with a screwdriver and into position but the second one won't go. Any ideas on how to compress the spring and get it into place? I keep getting a "U" shape in the middle and can't get it onto the rod. This will be the last time I ever take it apart!!!!!
