The Firefield FF39018 laser boresight is a brass boresighter that is inserted into the chamber of a 9mm pistol like a normal cartridge and projects a red laser dot showing exactly where the barrel is pointing. By adjusting the windage and elevation of the sights or optic to the laser dot, the firearm is boresighted and ready for final zeroing, saving time and ammunition.
