Abstract
The specification discloses a system and method for boresighting a firearm using laser technology. More specifically, the system includes a light source for directing a collimated beam of light through the barrel and a muzzle insert defining an aperture having a smaller diameter than the collimated beam. Both the light source and muzzle insert aperture are concentric with the barrel bore, such that the light beam emitted from the bore is a coaxial extension of the barrel usable for boresighting purposes. In a preferred embodiment of the invention, the muzzle insert includes a translucent material such that the location of the beam on the insert can be monitored to facilitate alignment of the beam with the barrel.
