Abstract
A scope assembly for use with a projectile firing device including an erect image telescope mounted upon the device. The telescope includes a housing with a series of spaced apart lenses, a reticle display field being disposed along an optical path established within the telescope and which is viewable by a user. A laser range-finding scope is housed within a component in parallel disposed fashion relative to the erect image telescope, the range-finding scope incorporating a microprocessor and timer in operative communication with a pulse generator and an infrared projector. The distance to the target is measured by the laser, pulse detector, and timer. The data is transmitted to the microprocessor which determines the vertical position required to hit the target. The compensated target aimpoint is then illuminated in the reticle display field as a horizontal line.
