Hi Don, it could work out that way, but if the receiver is ruined from trying to extract the set screw, your all done.... and in the trash it goes.. my experience has been it's better to sacrifice the bad parts, and have access to both ends, then it is to drill, pound, drill and heat into submission... Just a little grinding to make all better?... Best to you my friend! Til....lat'r.....GT.....
