Laser bore sighters have revolutionized firearm zeroing, offering a faster, safer, and more precise method compared to traditional techniques. This guide provides a comprehensive walkthrough of how to use a laser bore sighter effectively, ensuring accurate results and maximizing your shooting experience. We'll cover everything from choosing the right tool to troubleshooting common issues.
Choosing the Right Laser Bore Sighter
Before diving into the how-to, selecting the appropriate laser bore sighter for your firearm is crucial. Consider these factors:
- Caliber Compatibility: Ensure the bore sighter is designed for your specific firearm caliber. Using an incompatible sighter can damage both the sighter and your weapon.
- Laser Type: Red lasers are generally sufficient for most applications, offering good visibility in various lighting conditions. Green lasers, while more expensive, boast superior visibility, particularly in bright sunlight.
- Battery Life: Opt for a sighter with a long battery life to avoid interruptions during your zeroing process.
- Durability: A robust design is essential to withstand the rigors of use and prevent damage.
Step-by-Step Guide to Using a Laser Bore Sighter
Follow these steps for accurate and safe use of your laser bore sighter:
1. Safety First!
- Always treat your firearm as if it were loaded. Never point it at anything you are not willing to destroy.
- Ensure the firearm is unloaded. Visually inspect the chamber and magazine to confirm it's clear of ammunition.
- Wear appropriate eye protection. Laser light can be harmful to your eyes.
2. Inserting the Laser Bore Sighter
- Carefully insert the laser bore sighter into the barrel of your unloaded firearm. Ensure it's seated firmly and straight.
- Avoid forcing the sighter. If it doesn't slide in easily, check for obstructions or alignment issues.
3. Activating the Laser
- Turn on the laser bore sighter according to the manufacturer's instructions. This usually involves pressing a button or switch.
- Check the laser's functionality. Ensure the laser dot is visible and projects a consistent beam.
4. Aiming and Adjusting
- Find a safe area to aim. Ideally, a shooting range or a designated area with a suitable backstop.
- Aim the firearm at your target. Observe the laser dot's point of impact on the target.
- Adjust your firearm's sights or scope to align the laser dot with your desired point of aim. Remember, the laser only shows the point of impact at the bore; any deviations will indicate the adjustments needed.
5. Removing the Laser Bore Sighter
- Once adjustments are complete, carefully remove the laser bore sighter from the barrel.
- Inspect the bore for any debris or damage.
6. Verify with Live Fire
- The laser bore sighter is a valuable tool but should be verified with live fire. Always practice safe firearm handling techniques. Start at a shorter range, then progressively increase distance.
Troubleshooting Common Issues
- Laser Dot is Dim or Inconsistent: Check the battery, ensure proper insertion, and inspect the laser for any damage.
- Laser Dot is Off-Target: Double-check the sighter's insertion; it might be slightly misaligned. Repeated measurements and adjustments are essential for accuracy.
- Sighter Won't Insert: Examine the bore for any obstructions and ensure the sighter is compatible with your firearm's caliber.
Conclusion
Using a laser bore sighter can significantly improve the accuracy and efficiency of your firearm zeroing process. By following this guide and practicing safe firearm handling techniques, you'll be well-equipped to achieve optimal accuracy with your firearm. Remember that while a laser bore sighter offers a convenient method for initial zeroing, always verify your zero with live fire at the range. This ensures you're confident in your firearm's accuracy and ready for your next shooting experience.
