Laserlyte has always been about innovation, and this is especially prevalent in Laserlyte Bore Sights. Laserlyte started as a gun accessories business about a quarter century ago, and they grew quickly. Laser bore sights are synonymous with them because they developed the first laser bore sighter for the commercial market! This innovation has been adopted by many other brands, but Laserlyte Laser Bore Sights still possess a quality that is essentially unbeatable. All other laser bore sights are imitators. If you want the original make sure you save money sighting in your new rifle scope with a Laserlyte Bore Sight.
