A rotational position sensor assembly for detecting the selected rotational position of a rotatable selector is provided including a reference member positioned about an axis; one or more proximity sensors disposed on the reference member; a rotatable selector defining an inner surface, the rotatable selector mounted about the reference member and rotatable about the axis, the inner surface and the proximity sensor defining a gap there between, wherein the gap varies with respect to the rotational position of the rotatable selector, the one or more proximity sensors generating signal(s) proportional to the size of the gap; and a processor and a non-transitory computer readable storage medium, the computer readable storage medium including instructions executable by the processor to receive signal(s) proportional to the size of the gap from the one or more proximity sensors; and correlate the signal(s) with a rotational position of the rotatable selector.

An adjustable zero-stop turret assembly for an optical firearm scope, the turret assembly defining an axis and including: a turret housing with a cavity to receive a head portion of a main turret screw and including a wall portion defining an opening; a rotatable zero-stop element carrier including a base portion, an upper portion and a first zero-stop element coupled to the base portion; an adjustable set screw adjacent the opening; a second zero-stop element receiving the screw, a first portion of the second zero-stop element positioned within the opening, and a second portion of the second zero-stop element projecting outside the opening and into the turret-housing cavity. The second zero-stop element travels axially along the screw from a first position to a second position. In the second position, portions of the first zero-stop element and the second zero-stop element reside in a common plane perpendicular to the axis.

The sight includes a main body, a regulating bolt movably joined to the main body, a securing bolt fixed to the regulating bolt, a regulating cover covering the regulating bolt and movable between a first position and a second position with respect to the regulating bolt, a first magnet disposed on the regulating cover, and a second magnet disposed on the regulating bolt and corresponding to the first magnet. The regulating cover is movable with respect to the regulating bolt when the regulating cover moves away from the second position. The regulating cover abuts the securing bolt and is rotatable with respect to the regulating bolt when the regulating cover moves to the first position. The regulating cover engages the regulating bolt when the regulating cover moves to the second position. The regulating cover is maintained in the second position through attraction of the first magnet and the second magnet.

An adjustment assembly having a rotary encoder, riflescopes incorporating the same, and related methods are provided. In one example, an adjustment assembly includes a first rotational component configured to rotate about an axis, a first gear coupled with the first rotational component and a second gear coupled with the first rotational component. The assembly further includes an encoder. The encoder includes a position gear engaged with the first gear, the first gear and the position gear having a 1:1 gear ratio, and a revolution gear engaged with the second gear, the second gear and the revolution gear having a gear ratio other than 1:1, wherein the gear ratio of the second gear and the revolution gear independent of a ratio of the respective diameters of the second gear and the revolution gear. Sensors may determine the rotational positions of the position sensor and the revolution sensors.

A sighting device, including an optical element having a concave reflection surface and an aiming light source and forming in a visual field frame, comprises a main-body housing section that houses the optical element and the aiming light source and has an opening on an upper surface side, a cover member that covers the upper surface side of the main-body housing section, and a link mechanism that couples the main-body housing section and the cover member and moves the cover member with respect to the main-body housing section. The cover member is moved by the link mechanism between a closed position where the cover member covers the opening of the main-body housing section and an open position where the cover member is disposed in a position separated from the opening of the main-body housing section and forms an optical path of the aiming light.
