Laser bore sighting your rifle is a crucial step in ensuring accurate shot placement before heading to the range. This method offers a quick and convenient way to get your rifle close to zero, saving you time and ammunition. While it doesn't replace proper zeroing at the range, it significantly reduces the initial adjustment needed, leading to faster and more efficient sighting-in. This guide will walk you through the process, covering everything from choosing the right tools to troubleshooting common issues.
What is Laser Bore Sighting?
Laser bore sighting uses a small, self-contained laser device inserted into the barrel of your firearm. This laser projects a visible beam that represents the bore's line of sight. By aligning the laser with your scope or iron sights, you can roughly align the rifle's point of impact with your aiming point. This significantly reduces the time and ammunition spent at the range performing fine adjustments.
Tools and Equipment You'll Need
Before you begin, ensure you have the following:
- Laser Bore Sighter: Choose a bore sighter compatible with your rifle's caliber. Different calibers require different-sized bore sighters. Improper sizing can damage your firearm.
- Your Rifle: Ensure your rifle is unloaded and the action is open. Safety is paramount.
- Your Scope or Iron Sights: Make sure these are properly mounted and tightened.
- Target: A target placed at a suitable distance (ideally 25 yards or more) is essential for verifying alignment.
- Target Stand: Ensure stability so your target remains still during the process.
- Safety Glasses: Always wear safety glasses to protect your eyes from accidental laser exposure or any potential debris.
Step-by-Step Guide to Laser Bore Sighting
1. Preparation is Key:
- Safety First: Double-check that your firearm is unloaded and the action is open. Visually inspect the chamber and magazine well. Treat every firearm as if it were loaded.
- Stable Setup: Place your rifle on a stable surface, ensuring it won't move during the process. A vise or sandbags can be helpful.
- Prepare your Target: Set up your target at your chosen distance. Remember, accuracy increases with distance, but start closer if needed.
2. Inserting the Laser Bore Sighter:
- Carefully insert the laser bore sighter into the muzzle of your rifle barrel. Ensure it's fully seated but don't force it.
- Turn on the laser: Most bore sighters have a simple on/off switch.
3. Aligning the Laser with Your Optics:
- Position yourself behind your rifle: Aim the rifle at your target.
- Adjust the rifle's position: Carefully adjust the rifle's elevation and windage until the laser dot aligns with the center of your scope's reticle or your iron sights.
- Make minor adjustments: Use the adjustments on your rifle to fine-tune the laser's alignment.
4. Verification:
- Observe the laser dot on your target: Once aligned, carefully remove the laser bore sighter.
- Fire a few test shots (at the range): This step is critical. The laser bore sight provides a rough alignment; you'll still need to fine-tune your zero at the range using live ammunition.
5. Fine-tuning at the Range:
- Proceed to a safe shooting range: Never conduct live fire exercises outside a designated range.
- Fire groups at your chosen distance: Adjust your scope or sights based on where your shots land relative to the center of your target.
- Continue adjusting until you achieve your desired level of accuracy.
Troubleshooting Common Issues
- Laser doesn't turn on: Check the batteries and ensure the bore sighter is properly switched on.
- Laser dot is not visible: Check the laser's battery level and ensure there are no obstructions between the laser and the target. Adjust brightness settings if possible.
- Inconsistent results: Repeat the process several times. Inconsistent results can indicate a problem with the bore sighter, the rifle, or the mounting of your optics.
Conclusion
Laser bore sighting offers a significant advantage in the initial setup of your rifle's optics. While it is not a substitute for proper zeroing at the range, it substantially reduces the time and ammunition required. By following these steps and prioritizing safety, you can accurately align your rifle's optics and improve your shooting accuracy. Remember always to follow safe gun handling practices.
