The Sightmark Triple Duty Universal Red Laser Boresight (brand part no. SM39024) sights in rifles, shotguns, and pistols from .17 caliber up to .50 caliber using a single unit, tested and recommended by the National Tactical Officers Association and the North American Hunting Club. Instead of chambering inside the barrel, the self-centering arbor attaches magnetically to the muzzle, which means there are no small attachment pieces to lose in the field and no metal protruding into the bore.
