Prismatic boresighter
First Claim
1. An optical collimator device for aligning a riflescope with the bore of a rifle barrel comprising, a reticule mounted to a block of optically clear material, a lens mounted to said block of optically clear material for viewing said reticule and providing a reticule image, forming a collimator, and where said block of optically clear material has internal reflecting surfaces that aligns the longer section of the optical path between said reticule and said lens, to be perpendicular to the bore of the rifle barrel, and said collimator arrangement when viewed with said riflescope, allows a target to be viewed simultaneously with said reticule image.

Abstract
An optical collimator device, for use in aligning a riflescope with the bore of the rifle, is formed using a small aperture lens for viewing a reticule through a prismatic assembly. The collimator is magnetically attached to the muzzle of the rifle, and when a target is viewed through the riflescope the image of the reticule and the riflescope cross wires are seen simultaneously with the image of the target.
