FN Forum.NET :: View topic - PS90 pre-sighted in?: "If anyone wonts to boresight a PS90 just grind off the backend of a spent brass case, clean inside with 320 grit sandpaper on a rod, then press in an AimShot .17HMR boresight laser. Use a vernier to get a .003 press fit on a wooden block. I can make them up from your brass formed to your chamber if anyone is interested."
