ABSTRACT:
A sighting device for aiming a firearm, particularly handguns, employs a rib upon which a rear sight leaf is pivotally mounted. Attached to the leaf is a plurality of downwardly projecting elevation screws terminating at selectively adjustable and predetermined distances from the leaf. A finger-operated elevation wheel beneath the screws has an upwardly facing elevation ramp therein which is rotatable about a vertical axis (assuming that the firearm is held in a normal firing position) to any one of a plurality of angular positions. Rotation of the wheel towards a selected position concurrently rotates the elevation ramp into initial sliding engagement with an overlying elevation screw. Subsequent seating of the elevation screw in a recess on the ramp sets the elevation of the sight leaf. An indicator on the wheel indicates to the shooter which screw is seated and, thus, which sight elevation is in use.
