I was in the process of installing a Boyds Rimfire Hunter stock and noticed a small portion of the trigger assembly housing had broken off and fell out, it looks like a small hook tab that rides in a slot cut into the bolt, one of the sides was wearing quite a bit, I have searched the web for a replacement part but came up empty, anyone run across this problem and know of the correct fix This is a 93FVSS 22 magnum.
