Depending on the type of laser bore sight you choose, you will wither need to charge the device or ensure batteries are installed properly. Devices that require charging can normally be charged with a standard USB port from most charging devices. If your device is battery powered, chances are it takes CR2032 or CR123A batteries. These batteries should last for a very long time (~1 year).

3) Prepare Your Adapter

Grab your adapter & screws that match the caliber of your weapon. Adapters are usually NOT one-size-fits-all. So make sure you use the correct size for your weapon. Secure the adapter to your weapon.

4) Set Up Your Gun Vice

If you want to make precision adjustments, you need something to secure your weapon. I recommend using a gun vice to hold it in place. If you don’t have access to a gun mount or vice, don’t panic. You can use your hands to make manual adjustments. However, it won’t be as accurate.


5) Line Up Your Sight

For me personally, I place my shooting target 25 yards down range. You can choose the distance that works best for your needs, but 25 yards is recommended. Align your sight with the center of your target. Make sure your gun’s sight matches the laser.

6) Verify Zero

Make any attachments necessary to ensure your sight is aligned. If you are using a scope, modify your windage and elevation settings to align with the laser bore sight.

7) Detach Your Laser Bore Sighting Device

Remove your laser bore sighter and enjoy your calibrated weapon! Be sure to turn off the laser before removing to avoid accidentally pointing it into your eyes.

How To Choose Your Laser

There are two main considerations when choosing a laser bore sighting device.

  1. Class – Class III is the most common
  2. Color – Green is preferred

Most laser bore sighters are class III lasers. This means that they are powerful enough to see from a distance, but are not super dangerous for the eye. The lower the laser class, the more powerful and visible the laser dot.

When it comes to laser colors, red & green lasers are the most popular. For most people, green lasers are the most visible in all light conditions. However, for purposes of zeroing your sight either color will work just fine.

Benefits of Laser Boresighting Process

There are a lot of benefits to using a laser bore sighting process.

  • Improve the accuracy of your weapon
  • Save money on ammunition
  • Quick sighting process that saves time

Laser boresighting is a quick and efficient process, and it can save both ammo and time at the range. Because the laser is Sighted in before firing the gun, there is no need to waste ammunition on sighting in shots.

This can save hundreds of dollars in ammunition costs over the lifetime of a gun. Using laser dot can be a godsend for hunters who don’t have time to waste sighting in their guns every time they go out hunting.

Boresighting Without A Laser

Boresighting your weapon without a laser is also an option. Basically, you fire a round and see where you stand, then adjust your scope to compensate.

After taking a shot you can walk up to the target to measure the point of impact. Check how far off you were both horizontally and vertically. Next, translate your measurements to “clicks” on their scope’s windage and elevation dials.

Bore sighting without a laser is not the most accurate method, but it’s better than nothing. If you’re really serious about getting the best possible sight picture, you’ll invest in a laser bore sight.

Bore Sight To Zero A Red Dot Sight

Laser bore sighting a weapon with a red dot sight is a simple process. In fact, if you do it right, you can get your sight dialed in without firing any rounds on target.

  • Attach your laser to the barrel of your gun
  • Align the laser with the target’s center
  • Use windage and elevation settings to alight the red dot with the laser bore sight
  • Fire a few rounds & make further adjustments to elevation & windage settings

Sighting in your red dot sight or reflex sight works best with distances of 50 yards or less. I prefer to alight my red dot sight at 25 yards. Keep in mind that bore sighting is only a rough approximation, so be patient and do some fine-tuning at your preferred range.

Best Distance For Laser Bore Sighting Devices

For most shooters, the best distance for zeroing your weapon with a laser bore sight device is 25 yards down range. This is because the further down range you go, the more the weapon will be affected by factors such as wind and gravity. Additionally, 25 yards is close enough that you can still see the laser beam clearly.

You may hear some stories of people zeroing their sights up to 100 yards. This can be an effective strategy if you plan on doing some long-range shooting. If you plan to shoot from further distances, you should probably go with a 3 MOA dot sight. The difference between 3 MOA and 6 MOA can be significant at longer distances.
