Claim:
A rifle scope with adjustment stop comprising: a scope body; a movable optical element defining an optical axis, the optical element being operably connected to the scope body; 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 having a first cap operably connected to the screw to adjust the position of the screw; the turret having a stopper assembly selectably engaged to the first cap; the stopper assembly of the turret having an internal stop element; the stopper assembly defining a stop surface positioned for engagement by the turret stop element to limit rotation of the screw in one direction while allowing unlimited rotation of the screw in the opposite direction, such that the relative position at which the stopper assembly is secured to the first cap defines a zero position of the screw and the movable optical element; and the stopper assembly of the turret being covered by the first cap while setting the zero position of the screw and the moveable optical element, the zero position being defined by the relative position at which the stopper assembly is secured to the first cap.
