A day-night rifle sight, using separate parallel day and night sights combined by means of a beam splitter; is improved by: integrating the housings of the night sight and beam splitter, reducing the outer dimensions, sealing and strengthening the coupling between the from ends of the sights; adding a quick release clamp to the rear ends; reducing the image size of the night sight with a fiber optic taper to match the daysight image and reticule; reducing the size of image forming optics and thereby reducing the inner dimensions of the coupling.
