I know this is an old post but hoping I will get some help with the correct size for my front sight replacement to get my POA lowered 8”. As outpost stated every .15” of adjustment raises or drops POA approx 3.9”. That means I need a front sight .3” higher then my factory W stamped sight. There is no number marked on my front sight only a W. Does someone know what front sight blade height I need to zero my POA with my battle peep? I’m hitting 8” high right now at 100 yards. Thanks.
