NOTE: Since the sight sits at height of typical line of sight on rifles when installed. You might have a partial view of iron sights on the rifle while looking thru the sight. It is recommanded that iron sights be removed if they are removable. Or you might want to use a riser to raise up the sight. Should a riser is used, you may need a different type of rings for mounting the sight depending on the type of rails on the riser chosen.
