ABSTRACT:
A device for aiding in the cross-hair alignment of the reticle of a gun-mounted telescopic sight wherein the gun includes at least one scope base for securing the telescopic sight. The device includes a light source for projecting a beam of light against a surface. The light source is mounted to the scope base of the gun. The projected light beam is modified to form a reference line which may be viewed through the telescopic sight. The projected reference line is automatically aligned with the barrel axis of the gun. One of the cross-hairs of the reticle of the telescopic sight may be compared with the aligned projected reference line and adjusted accordingly to align the cross-hairs with the barrel axis of the gun.
