Save time money and ammunition with the new and improved LaserLyte® Laser Bore Sight. Incorporating LaserLyte's patented one-piece design and caliber-fitting systems the new Laser Bore Sight is fifty percent smaller than the previous model. This easy-to-use product can get a shooter within three to four inches of the bull's-eye at 100 yards in about three shots. - Constructed from tough T6 aluminum the Laser Bore Sight comes in a sleek red finish and works great on any weapon with at least three inches of barrel length. The Laser Bore Sight makes sight-in sessions a breeze for scopes lasers or iron sights on any firearm from .22 to .50 caliber with included adapters. - For maximum versatility the system also works with new accessories (sold separately) including a shotgun adapter for .50 to .75 caliber and improved scope leveler. The Laser Bore Sight activates with a roll switch and is powered by three 393 batteries that provide one and a half hours of continuous use. This unit is also excellent for modern rifles and its modest design works great with most flash suppressors and muzzle breaks. - SPECIFICATIONS: - Product Number: MBS-1 - Compatible Firearms: .22 - .50 Caliber minimum 3-inch barrel - Power Output: Class IIIA 5mw - Laser module: 650nm - Batteries: 3-393 batteries - Battery Life: 1.5 hours constant on - Material: 6061 T6 aluminum - Weight: .75 oz. 20 g - Length/Max.
