ABSTRACT:
A sighting device completely devoid of any lenses for use in pistol target shooting has a one-piece elongated outer tube having at least one saddle integrally formed on the outer tube and located proximal to one of the ends of said main tube. The saddle has two holes in it passing through the saddle into the interior of the main tube which provide access into the interior of the main tube. The holes are placed on the saddle 90 degrees apart from each other. Located on the saddle over each of the holes is a turret member. A portion of each of the turret members passes through each of the holes into the interior of the main tube. Mounted within the interior of the main tube is at least one elongated inner tube. The inner tube is pivotally mounted within the main tube such that one of its ends is free to move within the interior of the main tube. The portions of the turret members that pass through the holes are operatively connected to this movable end of the inner tube and this end of the inner tube moves within the interior of the main tube in response to movement of the turret members. A reticle composed of two sections which together form a complete reticle has one of its sections located on the movable end of the inner tube and has the other of its sections located within the main tube proximal to the end wherein the saddle is not located. The two sections of the reticle together form a complete reticle when viewed down the longitudinal axis of the sighting device.
