Tacticon laser bore sight. - Tacticon Armament Universal Laser Boresight

I used my bore sighter on a Walter P22 for testing of the sighter as well as setting the red dot & laser. I fully expected slight movement as u turn the laser in the bore. There was none the green dot did not very no matter how much i turned the laser as long as it was firm in the bore. Dead on accurate out of the box. You do have to use the correct tip for your caliber and not necessarily the one labeled with that caliber.
