Thanks. The rail is a short diamondhead (went to a stag arms 3T-M).
It's a little closer to the trigger than I would have liked, but that's where the stock allowed me too drill and bolt. In a standing position, without a bipod, I basically put my hand on the rail, kind if a point of reference. Maybe I will get a soft cover for it.
Anyway no glass beading yet, but I did relocktite the trigger adjustment set screw. Also set it to a lighter poundage.
