David.... sight heigths...
Front sights came in three standard heigths, differing by .1mm.... the difference is noticable on the flange section above the dovetail. The shortest sight has no flange and the highest has a relatively thick flange... Tom Heller would know more obout this, but it seems that even if you had the shortest, and went to the highest, your gun would still shoot high...
just my 2 cents, fgr
