Abstract
A simple and compact device is disclosed for enabling the boresight alignment of the bore and optical sight of a firearm. An optical assembly, beam splitter, and illumination source assembly are integrated into an enclosure. The firearm bore is referenced mechanically to the enclosure. The illumination source provides visible light which is directed by the beam splitter into the firearm bore. The bore is illuminated from the muzzle to the chamber. This is observed when viewed through the firearm optical sight. Azimuth and elevation adjustments are made in order to bring the images of the muzzle and chamber into coincident alignment. Once this is accomplished, the cross hair of the firearm optical sight is adjusted to bring the cross hair into alignment with the muzzle, bore, and chamber images. The bore and optical sight are boresighted.
