Laser Bore Sight Kit for .22 to .50 Caliber Pistols and Rifles

1. First, insert 3 batteries into the battery holder as shown in the image.
2. Then, insert the battery holder into the boresighter's battery compartment.
3. Once the 2 points are aligned, the boresighter will be ON. If they're not aligned, the boresight will be OFF.
4. To align the points, rotate the battery holder.
5. Select the appropriate adapter for your barrel size.
6. Choose the correct size adapter and use the screwdriver to tighten the screw into the adapter. Ensure that the size is suitable to fit in your barrel.
7. Next, insert the boresighter into the barrel of your firearm.
8. Push the small end of the boresighter with the adapter into the barrel, ensuring it is inserted snugly with the crown of your firearm.
9. When you turn on the laser, a small red laser dot will be emitted. You can then adjust your scope's windage and elevation so that your crosshair aims at the red dot.
10. To adjust the laser up and down, loosen the relevant screw with a wrench and then slowly tighten the opposite screw until the laser point is in the desired position.
11. For adjusting the laser left and right, follow the same process with the appropriate screws.
