Abstract: A sighting device for use with firearms and the like under varied ambient light conditions comprises a base member for mounting relative to a firearm or the like and an upstanding sight member. The sight member includes an intermediate surface that has a reflective finish and that is inclined upwardly and rearwardly so as to reflect ambient light from above rearwardly toward a sighter's eye. The rear end of the sight member defines a through aperture and is dimensioned so that it masks the inclined reflective surface from view from the rear except for that portion thereof that is exposed through the aperture. The aperture and inclined reflective surface combine to present a bright bead contained in the relatively dark border of the rear face of the sight member which is useful in attaining an accurate sight under both bright and dim ambient light conditions. A front sight embodiment having a single aperture and a rear sight embodiment having two spaced apart apertures are disclosed.
