Abstract
Rifle scope turrets with spiral cam mechanisms 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 spiral cam mechanism engaged thereto. The turret defines first and second stop surfaces positioned for engagement by the spiral cam to limit rotation of the turret. The first stop surface defines a zero position of the screw and the movable optical element. The second stop surface defines a maximum point of displacement of the screw and the moveable optical element. The stop surfaces may be defined by a spiral cam groove in the indexing portion of the turret. The groove may overlap itself at least partially. The turret may be an elevation turret or a windage turret.
