Another possibility is to get out he Dremel, a supply of bedding epoxy, and the instructions and redo the bedding job. You can't do worse than that job, and in any event you will have had a fun practice.

My first Garandicon would not lock up tight so I did just that. Not quite as neat as the SA job, but close. It is still my most accurate and the one I would grab if I needed to go into harms way.
