Claim 7:
8. A rifle scope with spiral cam turret mechanism:
a scope body;
a movable optical element defining an optical axis connected to the scope body;
an elevation turret having a screw operably connected to the movable optical element for adjusting the optical axis in response to rotation of the screw;
the elevation turret having a knob operably connected to the screw to adjust the position of the screw;
the elevation turret having a first stop surface positioned for engagement by a stop element to limit rotation of the elevation turret, such that the position at which the stop element engages the first stop surface defines a first limiting position of the screw and the movable optical element;
the elevation turret further having a second stop surface positioned for engagement by the stop element to limit rotation of the elevation turret, such that the position at which the stop element engages the second stop surface defines a second limiting position of the screw and the moveable optical element;
wherein the first and second stop surfaces-are defined by a groove, and further wherein the groove defines a first transition and a second transition when the groove overlaps itself for the first time and second time, respectively, and wherein rotation of the screw causes the screw to move generally perpendicular to the optical axis; and
an elevation indicator coupled to the stop element that moves outward radially from the elevation turret each time the elevation turret is rotated.
