A bow hunting sight has a base defining a front, a back, sides, a top, and a bottom. At least one hole extends between the front and back of the base. The base further has at least one bore which extends generally perpendicular to, and intersecting with, the front-to-back hole. A carriage is pivotally and slidably received in the bore and is exposed through the front-to-back hole. The carriage has a threaded bore extending longitudinally therethrough through which an aiming pin is threadably received. A single set screw is used to lock the aiming pin against both pivotal and axial movement. The set screw is movable between a locking position in which the set screw urges the carriage inwardly to urge the aiming pin against a surface of the front-to-back hole to prevent both pivotal and axial movement of the pin and an unlocked position in which the carriage may move axially in the bore such that the aiming pin may be moved both pivotally and axially.
