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.

Boresight correlator

A boresighting system including an optically pumped target member for correlating the boresight between a plurality of components such as a laser rangefinder/designator (LRF/D), a thermal imager such as a Forward Looking Infrared (FLIR) device, and a video system. The laser rangefinder is used as a reference with which to align the thermal imager and the video system. The target member and a visible source generator of the boresighting system provide multispectral capability without using any driving electronics. Both the target member and the visible source generator are located at the geometric focus of collimating optics used with the system, and, since, by definition, the geometric focus is equivalent to infinity, a point souce of radiation by the optically pumped target and the visible light generated by the visible source generator will appear to be extended sources from infinity.

Passive boresighting system

Apparatus for boresighting a firearm which utilizes a source of light such as a laser transmitter. A light-receiving and directing device carried on the bore directs a light ray along the axis of the bore of the firearm to a target. An optical sight carried on the firearm is adjusted in azimuth and elevation to be in alignment with the light ray as it reaches the target. The source of light is remotely located from the bore of the firearm.
