Abstract
A light dot reticle rifle shooting sight has tubular lens and battery housings supported in parallel for movement from right-handed to left-handed shooter positions by 90 degree rotation of a circumferential groove on the lens housing relative to a pin projecting into the groove from a mounting strap. Elevation and windage adjustments of the light dot are provided by adjustment screws that pivot a lens tube against diametrically opposed rubber biasing cushions and a coaxial position restoring force of a rubber ring fulcrum through which the tube extends. Rotation of the sight from right- to left-handed position interchanges the elevation and windage adjustment functions of the screws.
