Reduce wasted ammo and keep precision accuracy at your fingertips with the Firefield .223 Remington Laser Bore Sight. The fastest gun zeroing and sighting system there is, the laser bore sight attaches easily to the rifle to begin shooting in minutes. Once placed in the chamber of the firearm, the red laser dot appears exactly where the barrel is pointed, allowing the weapon sights to be adjusted to the theoretical impact point. Live fire is only needed to fine tune for bullet drop and windage compensation. Whether used for hunting or target shooting, Firefield bore sights enhance every adrenaline filled moment.
