Saves time and money
Allows for initial sighting in of optical sights
These caliber specific arbors accept the Aimshot Bore Sight 223 Laser Diode Module. Simply insert the module into the arbor and then insert the arbor into the chamber. A bright laser beam shines through the bore of the gun and is visible on the target, allowing for initial sighting in of optical sights. This system saves time and money that would otherwise be wasted getting the shots "on paper." For 7.62 x 39mm, 220 Swift, 303 British.
