Site-A-Line, kits and accessories

Site-A-Line, Nothing is better than an optical bore-sight collimator for calibrating firearms. We brought the original Sweany Site-A-Line (original the Sweany Optical Bore-Sight-Collimator) on the market in 1958 and it has been the mainstay of the industry ever since. Gunsmiths can't do without one. Sharpshooters needs one. The Site-A-Line was originally designed for sporting arms but during World War II it was used to bore sight and align (parallel) five-inch thirty-eight Naval guns.
