I have a J. Stevens 520 12 gauge I need help with. The serial number is 95---A.
1) On the shell stop, does it need to pivot freely with little or no play? The one in my receiver seems to flop around. Can the screw bushing/nut be adjusted to eliminate the flop?
2) The lifter spring now is a single leaf which seems too weak to push the lifter up. Do I need a double leaf?
Thank you!
