Disclosed is a riflescope that incorporates physical measurements and user specific firearm parameters to calculate and designate the target impact point. The scope incorporates a laser range finder with the receiver integrated into the visual sight path thus utilizing the large objective aperture to collect as much reflected light as possible. This ensures long distance operation while maintaining a compact form factor. The line-of-sight laser distance and inclination angle are measured and used to calculate the actual horizontal target distance. A user interface keypad and display provide a mechanism to enter in firearm and ammunition specific parameters such as muzzle velocity and ballistic coefficient. A barometric pressure and temperature sensor measure the actual air density; this and the user entered ballistic coefficient quantify the resulting bullet drag and thus resulting final velocity. All these physical measurements and user specific parameters are utilized to calculate the final bullet impact point. This compensated aim point is indicated by automatically adjusting the elevation reticle.
