ABSTRACT:
A crossbow or other weapon with an adjustable sight mounting member is provided with an indicator mechanism which provides a read-out indicative of the disposition of the sight mounting member, the indicator being of a size substantially greater than the range of adjustment of the sight mounting member so as to provide a readily legible visual indication of said disposition. The indicator comprises a pointer rotatably movable over an arcuate scale and driven by a rack and pinion connection with an operating member which is coupled with the sight mounting member. The sight mounting member is adjustable by means of a screw which is operable independently of the indicator.
