Variable beam boresight device

Abstract

A structure for visibly boresighting an invisible MILES-type laser beam emitted by a small arms transmitter to sights of a weapon intermittently projects a visible light beam that is parallel to the beam emitted by the MILES-type laser. Adjusting the visible beam to impinge on that portion of a target in the sights of the weapon also boresights the MILES-type laser to the weapon's sights.
