ABSTRACT:
An improved sighting screw unit for and with archery bows wherein the sighting screw unit is adjustable up and down within a particular slot of a bracket mount attached to the bow. The unit cooperates with the slot in a rack-and-pinion type of engagement. Means is provided for frictionally engaging the sighting screw of the unit and is constructed for keying to the pinion portion of the adjustment member of the unit such that the screw will rotate in one-to-one relationship with such adjustment member of the unit. In this way there is no windage change of the screw relative to the unit as the latter is moved up and down within the bracket-slot provided. The structure is constructed and dimensioned, and preferably also marked, for accurate indications of changes in vertical position for individual position replacements.
