Simply chamber the bore sighter like a normal cartridge and a laser will come out of the barrel showing exactly where your rifle is aiming. This will save time and ammunition as only a few shots will have to be fired for fine tuning.
Works on 3x AG3/LR41 batteries of 1.5 volts (not included)
Please note! do not use 312 batteries, these are 1.4 volts
