  • Patent number: 8984796
    Abstract: A scope adjustment system includes a turret cap assembly, a saddle assembly, and a quick spanner assembly. The turret cap assembly includes a ring with a plurality of regularly spaced apart teeth residing circumferentially around the ring. The saddle assembly includes a transportation element in mechanical communication with a plunger. The saddle assembly includes a click element to engage the teeth of the ring. The quick spanner assembly includes a bolt that may be coupled to the transportation element, a cam lock hinged to the bolt, and a pressure plate residing between the bolt and the cam lock. The bolt can be screwed into the transportation element, and the cam lock can be set to apply a force on the pressure plate such that the transportation element engages the plunger. When engaged, the plunger is responsive to rotations of the turret cap to adjust, e.g., an aiming reticle.
