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.
