Abstract: A method of boresighting includes providing a weapon including a bore having a centerline axis and a boresight telescope coupled into the bore. The boresight telescope has a beam splitter therein which directs image information received from an aiming reference to an eyepiece of the boresight telescope which is off-axis relative to the centerline axis. A boresight camera accessory (BCA) is removably coupled to the eyepiece. The BCA includes an objective and a photodetector array, wherein the objective focuses the image information from the eyepiece to the photodetector array which generates sensing signals. The sensing signals are automatically transmitted to at least one remote viewer, and a viewable image of the aiming reference is displayed from the sensing signals. The remote viewer individually boresights the weapon using the viewable image and a view of the aiming reference through the bore.

Abstract: A stem or adapter for boresighting weapons includes a first portion having a weapon insertion end including a centering device including a plurality of fingers which compress upon insertion into a bore of a weapon. A second portion has a first end attached to an end of the first portion opposite to the weapon insertion end. The second portion has a coupling end including an attachment feature opposite the first end for attaching another member thereto. The second portion is largely tungsten carbide, and the first portion is formed from a material that is largely not tungsten carbide to provide sufficient flexibility to allow the fingers to spring load when inserted into the bore of the weapon.
