Abstract
Rifle scopes with adjustment stops include a scope body, a movable optical element defining an optical axis enclosed by the scope body, and a turret having a screw operably connected to the optical element for adjusting the optical axis in response to rotation of the screw. The turret has a stop element selectably engaged to the screw. The body defines a stop surface positioned for engagement by the turret stop element to limit rotation of the screw, such that the relative position at which the stop element is secured to the screw defines a zero position of the screw and the movable optical element. The stop element is held against the stop surface by an indexing portion while the relative position at which the stop element is secured to the screw to define the zero position is determined.
