Laser bore sighters have revolutionized firearm sighting, offering a fast and efficient way to zero your rifle or pistol without expending ammunition. But using one correctly is crucial for accurate results. This guide provides a comprehensive walkthrough, covering everything from preparation to final checks.
What is a Laser Bore Sighter?
Before diving into the how-to, let's quickly define what a laser bore sighter is. It's a small device with a laser emitter that's inserted into the barrel of your firearm. When activated, the laser projects a beam that simulates the trajectory of a bullet. This allows you to quickly align your sights or scope without firing a single shot.
Essential Preparation: Safety First!
Safety is paramount when handling firearms. Always follow these steps before using your laser bore sighter:
- Unloaded Weapon: Ensure your firearm is completely unloaded. Visually inspect the chamber and magazine to confirm there's no ammunition present.
- Safe Environment: Choose a safe, controlled environment, preferably an outdoor shooting range or a dedicated shooting area with a proper backstop. Avoid areas with obstructions or potential hazards.
- Eye Protection: Wear appropriate eye protection. Even low-power lasers can cause eye damage if viewed directly.
- Hearing Protection (Optional): While you won't be firing, hearing protection can be helpful if you're working in a noisy environment.
Step-by-Step Guide to Using a Laser Bore Sighter
-
Insert the Laser: Carefully insert the laser bore sighter into the muzzle of your firearm. Make sure it's fully seated and aligned with the barrel's bore. Different sighters may have slightly different insertion methods, so consult your specific device's instructions.
-
Activate the Laser: Turn on the laser bore sighter. You should see a red dot projected from the muzzle.
-
Target Acquisition: Place your target at your intended shooting distance. This could be a paper target, a sturdy cardboard box, or any other suitable target. Adjust the distance to your preferred zeroing range.
-
Sight Alignment: Look through your sights or scope and adjust them until the laser dot aligns with your aiming point on the target. This is where careful adjustment is key. Small changes in sight adjustments will drastically alter where the laser dot hits.
-
Multiple Adjustments: Make small adjustments to your sights or scope, rechecking the laser's alignment on the target after each adjustment. Repeat this process until the laser dot is consistently hitting your desired point of impact.
-
Check Multiple Points: It is recommended to check the laser's impact point at several points of aim across the target, such as high, low, left, and right. This will help confirm that your adjustments are consistent throughout the field of view of your optics.
Post-Sighting Procedures
-
Remove the Laser: Carefully remove the laser bore sighter from the barrel of your firearm.
-
Final Check: It is still recommended to verify the zeroing at the range using live ammunition once you’re satisfied with your laser bore sight.
Choosing the Right Laser Bore Sighter
Different laser bore sighters are available for different calibers. Always ensure you purchase one that’s compatible with your firearm’s caliber.
Conclusion
Using a laser bore sighter can significantly speed up the sighting process. Remember that while it provides a good starting point, it's crucial to verify your zero with live fire. Safety should always be your primary concern when handling firearms. Always consult your firearm's manual and the laser bore sighter's instructions for specific safety precautions and operation details.
