What Is A Bushnell Laser Boresighter?
A laser boresighter is a device that emits a visible laser beam through the barrel of your firearm. This tool helps align your scope or sight with the bore (the center of the barrel). The Bushnell Laser Boresighter is known for its reliability and ease of use. It comes with multiple arbors to fit different calibers, making it versatile for various rifles, shotguns, and handguns.
Bushnell’s model is powered by batteries and is compact enough to fit in most gun bags. Its laser is strong enough to be seen indoors and outdoors in normal lighting. The device does not fire live ammunition. Instead, it projects a laser dot onto your target so you can adjust your scope accordingly.
Why Use A Laser Boresighter?
Using a laser boresighter provides several advantages:
- Saves Ammo: You waste fewer bullets because the initial alignment is done using the laser.
- Quick Setup: It takes just a few minutes to get your scope ready.
- Reduces Frustration: No need to guess or make random adjustments.
- Prevents Wear: Less shooting means less wear on your barrel.
Many shooters find that a boresighter gets them “on paper” (meaning the shots hit the target) much faster than traditional methods.
Comparison: Laser Boresighter Vs. Manual Boresighting
The table below highlights some differences between laser boresighting and manual boresighting.
| Feature | Laser Boresighter | Manual Boresighting |
|---|---|---|
| Speed | Fast | Slow |
| Ammunition Needed | None | Several rounds |
| Accuracy (initial setup) | High | Medium |
| Ease of Use | Easy | Moderate |

Getting Ready To Use The Bushnell Laser Boresighter
Before using the boresighter, make sure you have the necessary items and a safe workspace.
- Bushnell Laser Boresighter with all included arbors
- Batteries (usually included)
- Your firearm (unloaded and safe)
- Target (paper or cardboard, placed at 25 yards for rifles)
- Screwdriver or Allen wrench (if needed for scope adjustments)
- Good lighting
Always double-check that your gun is unloaded before starting. Remove the magazine and check the chamber visually and physically.
How do you choose the best distance to zero a red dot
How To Insert The Bushnell Laser Boresighter?
The boresighter comes with different arbors for various calibers. Choose the correct arbor for your gun:
- Select the right arbor: Match the arbor to your barrel caliber. For example, use the .223 arbor for a .223 rifle.
- Attach the arbor: Slide the arbor onto the boresighter’s shaft and tighten if needed.
- Insert into the barrel: Gently push the boresighter into the muzzle (front of the barrel). Do not force it. It should fit snugly.
- Turn on the laser: Usually, there is a switch or button. The laser dot should appear on your target.
Some Bushnell models have a self-centering design. This helps keep the laser perfectly aligned with your barrel.
Adjusting Your Scope Or Sight
Once the laser dot is visible on your target, you can start adjusting your scope or sight.
- Set your firearm on a stable surface: A gun rest or sandbags work well.
- Look through your scope: Find the center of your crosshairs.
- Compare the crosshairs to the laser dot: If they do not match, you need to adjust.
- Adjust windage and elevation: Use the adjustment knobs on your scope. Move the crosshairs until they are centered on the laser dot.
- Repeat as needed: Make small changes. Check after each adjustment.
For red dot sights or iron sights, align them with the laser dot the same way. This process usually gets your scope close enough that your shots will hit the target at the range.
Example: Typical Adjustment
If your laser dot is two inches to the right of your scope’s crosshair, turn the windage knob left until they align. If the dot is high, turn the elevation knob down.

Removing The Boresighter And Preparing For Live Fire
After your scope is aligned with the laser dot, turn off the boresighter and remove it from the barrel. Double-check that your gun is safe before handling.
- Remove the boresighter carefully.
- Store it and the arbors in a safe place.
- Re-insert your magazine and ammo only when ready to shoot.
Now, your scope is set for live fire. Your first shots should be close to the target. Fine-tune your scope at the range using real bullets.
Practical Tips For Better Results
Using a Bushnell Laser Boresighter is straightforward, but a few practical tips can help you get the most from it.
- Set your target at 25 yards: For rifles, this distance is ideal for initial sighting. For handguns, you can use 10 yards.
- Use a large, plain target: A white sheet of paper makes the laser dot easier to see.
- Check battery power: A weak laser can be hard to spot, especially in bright light.
- Work indoors if possible: Sunlight can wash out the laser dot.
- Avoid moving the gun: Keep your firearm stable throughout the process.
- Do not over-tighten the arbor: It should be snug but not forced.
- Clean your barrel before inserting: Dirt or debris can block the laser or scratch the device.
- Store the boresighter in its case: Protects it from damage.
Common Mistakes And How To Avoid Them
Many shooters make simple errors when using a boresighter. Here are some common mistakes:
- Forgetting to unload: Always check your firearm before starting.
- Using the wrong arbor: Make sure you use the correct size for your barrel.
- Misaligning the boresighter: If the boresighter is not centered, your scope will be off.
- Adjusting too quickly: Make small changes and check each time.
- Ignoring parallax: Some scopes have parallax adjustment. Set it properly for the distance.
- Not checking after removal: Sometimes the scope shifts slightly after you remove the boresighter. Double-check alignment before shooting.
- Failing to re-zero at the range: The boresighter gets you close, but always fire live rounds to finish zeroing.

Extra Insights Most Beginners Miss
- Laser boresighting does not replace live-fire zeroing. The boresighter gets you close, but you must fire real rounds to finish the process. Factors like bullet weight, barrel harmonics, and scope mounts affect your point of impact.
- Check mounting screws after boresighting. Sometimes scope rings loosen during adjustment. Tighten all screws before shooting.
- Use the boresighter for periodic checks. After rough handling or travel, use the boresighter to confirm your scope is still aligned. It’s not just for initial setup.
- Different lighting affects visibility. If you cannot see the laser dot outside, try using the boresighter indoors or in shade.
- A dirty barrel can scatter the laser. Clean the barrel before inserting the device.
Safety Reminders
- Always treat your firearm as loaded until you confirm it is safe.
- Never point your firearm at anything you do not intend to shoot.
- Keep fingers away from the trigger while boresighting.
- Remove ammunition from the workspace.
- Store the boresighter and batteries away from children.
