ABSTRACT:
An adjustable sighting means for a firearm which a shooter can adjust to give the desired point of impact. An elongated rib is adjustably mounted on the gun barrel. The rib can be adjusted in the vertical direction so that the forward end of the rib has a greater vertical movement than the rear end of the rib. The effective pivot point of the rib is to the rear of the rib at a theoretical point which remains constant and is selected to be the position of an average shooter's eye when in shooting position.
