US12546986 - Apparatus for remotely adjusting scope magnification
An apparatus has a ring adapter coupled to a magnification adjustment ring of a scope and a slider assembly carried on a portion of a firearm spaced from the adapter. The slider assembly has a slider configured for longitudinal translation relative to the firearm and has at least one front pulley located forward of the slider, and a pair of rear pulleys are located below the ring adapter. A cable couples the slider to the ring adapter, the cable extending from one portion of the ring adapter and around one of the rear pulleys, the cable then extending forward and around the front pulley and then rearward and around the other of the rear pulleys to another portion of the ring adapter. The slider is coupled to the cable, so that translation of the slider causes motion of the cable about the pulleys and corresponding rotation of the ring adapter.
