The SME Sight-Rite muzzle laser bore sighter covers .17 to .50 caliber firearms with one end-of-barrel tool (brand part no. XSI-LBK2). SME designs it to sit at the muzzle and throw a bright green laser, giving you a clear reference for aligning the bore with your sights or optic. Because it uses an end-of-barrel design, there is no metal-to-metal contact to mar the finish or rifling. A calibration target and a storage pouch or carrying tube come with it, so the kit is ready to go and easy to keep in a range bag.
