Abstract

An optical sighting system comprises an adjustable optical system and an adjustment member. The adjustable optical system comprises at least one optical adjustment, and an optical pathway that extends along a longitudinal axis of the optical sighting system. The adjustment member is coupled to the at least one optical adjustment, such that the adjustment member comprises an axis of rotation about which the adjustment member rotates to actuate the at least one optical adjustment. The axis of rotation about which the adjustment member rotates is substantially parallel to the longitudinal axis of the optical sighting system. The at least one optical adjustment comprises a vertical optical adjustment and/or a horizontal optical adjustment, and depending on the embodiment, the axis of rotation about which the adjustment member rotates substantially coincides with the longitudinal axis of the optical sighting system or is different from the longitudinal axis of the optical sighting system.
