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.

The patent describes an apparatus that allows for remote adjustment of a firearm scope’s magnification through a system of pulleys and a cable connected to a slider assembly. This setup enables the user to translate the slider, which in turn rotates the adjustment ring of the scope, facilitating easier magnification changes while aiming.

Claim 1

1 . An apparatus for rotating an adjustment ring to adjust the magnification of a scope of a firearm, the apparatus comprising: a ring adapter adapted to be coupled to an adjustment ring of a scope; a slider assembly adapted to be carried on a portion of a firearm spaced from the adapter, the slider assembly having a slider adapted for longitudinal translation relative to the firearm and having at least one front pulley located forward of the slider; a pair of rear pulleys located below the ring adapter; and a cable for coupling 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; wherein 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. a ring adapter adapted to be coupled to an adjustment ring of a scope; a slider assembly adapted to be carried on a portion of a firearm spaced from the adapter, the slider assembly having a slider adapted for longitudinal translation relative to the firearm and having at least one front pulley located forward of the slider; a pair of rear pulleys located below the ring adapter; and a cable for coupling 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; wherein 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.
