US Patent 9151570 Synchronized elevation trajectory riflescope

A riflescope comprises a body, an elevation knob, a windage knob, and an eyepiece. The elevation knob may be mounted on the body and configured to generate an elevation setting corresponding to the elevation of the riflescope. The windage knob may be mounted on the body and configured to generate a windage setting corresponding to the left and right offset of the riflescope. The eyepiece is for viewing a target and may include a display configured to show a range to the target as determined by the elevation knob or the offset determined by the windage knob.
