Abstract:
An adjustable rifle scope with detent mechanism for incremental adjustment of the rifle scope, comprising:an outer tube including a socket having a base; a spring including a detent structure, the spring located in and prevented from rotational movement in the socket of the outer tube, the spring providing a bias force for urging the detent structure away from the base of the socket; a jack screw extending through the outer tube and keyed to the outer tube to prevent the jack screw from rotating relative to the outer tube while allowing the jack screw to reciprocate relative to the outer tube; a rotatable jack nut engaging the jack screw; and a face associated with the jack nut for rotation therewith, the face including a set of spaced face structures sized to cooperate with the detent structure of the spring, the spring urging against the face with sufficient force to urge the detent structure into registration with one of the face structures, whereby, in response to rotation of the jack nut, the detent structure registers against the face structures with tactile clicks each indicating an incremental rotation and the jack screw moves an incremental distance with each of the clicks to adjust the rifle scope incrementally.
