Abstract During normal use the M-26/27 muzzle boresight device is a very accurate device for boresighting tank cannons. This report proposes technical improvements to the tool used for the collimation of the M-26/27 muzzle boresight device (MBD). In addition, this report makes recommendations to improve present allowable tolerances in these MBDs and suggests a field expedient method of correcting MBDs which exceed tolerances under field conditions. Keywords: Tank gun accuracy; Fire control system alignment; M-68 Cannons; M-256 Cannons; Gun sights; Optical reticle wedge. (EDC)
