Abstract:
1. An adjustable mounting system for a sighting device, the system comprising an adjustable elevation mount including: an adjustable sub-base having a vertical slot disposed laterally through the sub-base, the sub-base further having a cam bore disposed longitudinally within the sub-base so as to intersect the vertical slot; an elevation cam assembly having an elevation cam and a positioning rod attached to the elevation cam, the elevation cam having an angled slot disposed laterally through the elevation cam, the elevation cam slidably disposed in the cam bore so as to position the angled slot adjacent to the vertical slot; an elevation pin received through the vertical slot and through the angled slot, the vertical slot adapted to allow vertical travel of the elevation pin, the vertical slot and the angled slot cooperating to hold the elevation pin at a vertical position corresponding to the position of the elevation cam within the longitudinal bore; and an elevation adjustment dial attached to the positioning rod, the elevation adjustment dial adapted such that rotation of the dial causes longitudinal displacement of the elevation cam through the cam bore in a direction and distance determined by the direction and magnitude of dial rotation, said displacement of the elevation cam causing vertical displacement of the elevation pin within the vertical slot.
