1. A rifle scope comprising:
a scope body;
a movable optical element defining an optical axis connected to the scope body; a turret having a screw defining a screw axis and operably connected to the optical element for changing the optical axis in response to rotation of the screw;
a guide surface wrapping about the screw axis and terminating at first and second ends and further wherein the guide surface defines a first transition and a second transition when the guide surface overlaps itself for the first time and second time, respectively;
a cam follower element operable to engage the guide surface, and to engage the first and second ends, the engagement of the first and second ends defining rotational limits of turret; wherein each of the first and the second ends are at different radial distances from the screw axis; and
an indicator operably connected with the cam follower element, wherein the indicator moves outward perpendicular to the screw axis in response to rotation of the turret.
