Abstract: Described are devices for automated ballistic targeting that are attached to a rifle for firing ballistic ammunition, in which such rifle may have one or more barrels for use with one or more types of ammunition. Various embodiments use one or more mirrors and an optical splitter all of which may be position-fixed or adjustable, a collimator sub-system, a data input unit, and a ballistic computer, in which the elements are configured to provide a calculated ballistic trajectory to hit a target, to correct elevation and azimuth, and to generate an aiming point that is super-imposed visually on an image of the target when the rifle is correctly aimed to hit the target (even where the ballistic trajectory requires that the aim be on an elevation or an azimuth off the target). In various embodiments, errors in roll maybe indicated and corrected. In various embodiments, periscope functionality may be used.
