It fits in a groove in the top inside of the receiver with no play.

My buddy that owns the shotgun went camping last week, came back to town for a while, and then headed back to the woods. He may be back Tues - but I ain't betting on it. We worked on the shotgun a little; made no headway. He thinks we ought to go by "If it ain't broke, don't fix it." I can't think of a good argument (other than I'm curious to see what the problem is). I'm going to keep spraying and banging until he gets back.
