Accurately zeroing your firearm is crucial for safe and effective shooting. A laser bore sighter offers a quick and easy way to achieve a close zero before heading to the range, saving you time, ammunition, and frustration. This guide provides a comprehensive walkthrough on how to use a laser bore sighter effectively.
What is a Laser Bore Sighter?
A laser bore sighter is a device that uses a small laser to project a beam of light down the barrel of a firearm. This light indicates the point of impact, allowing you to adjust your sights or scope accordingly. They're incredibly useful for preliminary sighting and are particularly helpful for rifles and handguns with optics.
Choosing the Right Laser Bore Sighter
Before you begin, ensure you have the correct laser bore sighter for your firearm's caliber. Using an incorrect model can damage your weapon or the device itself. Check the manufacturer's specifications to ensure compatibility.
Step-by-Step Instructions for Using a Laser Bore Sighter
1. Safety First!
Always treat your firearm as if it were loaded, even when using a laser bore sighter. Point the weapon in a safe direction at all times. Ensure the area is clear of people and objects.
2. Prepare Your Firearm
- Unload your firearm completely. Double-check the chamber and magazine are empty.
- Engage the safety. This is critical for preventing accidental discharge.
- Secure the firearm. Use a gun vice or other secure method to hold your firearm steady during the sighting process. This minimizes movement and ensures accurate results.
3. Insert the Laser Bore Sighter
Carefully insert the laser bore sighter into the barrel of your firearm. Make sure it's firmly seated but avoid forcing it. Consult the manufacturer's instructions for precise placement and insertion techniques. Some models have specific insertion methods depending on the firearm type.
4. Turn on the Laser
Activate the laser bore sighter according to the manufacturer's instructions. Usually, this involves a simple switch or button.
5. Aim and Adjust
- Find a target: Position your firearm at a safe distance from a suitable target (a cardboard box or similar at 25 yards is a good starting point).
- Observe the laser point: Note where the laser dot appears on the target.
- Adjust your sights: Use the adjustment knobs on your firearm's sights or scope to align the laser dot with your desired point of impact.
6. Repeat as Necessary
Continue adjusting your sights and rechecking the laser point until the laser is hitting your target where you want it. Remember small adjustments can make a big difference.
7. Remove the Laser Bore Sighter
Once you are satisfied with the alignment, carefully remove the laser bore sighter from the barrel.
8. Final Verification at the Range
While a laser bore sighter provides a close zero, it's crucial to verify your zero at the range by firing several shots and making any fine-tuning adjustments needed. This is the only way to ensure your firearm is accurately sighted for optimal performance.
Troubleshooting
- Laser not working: Check the batteries and ensure the device is properly switched on.
- Laser is not aligned: Ensure the laser bore sighter is correctly seated in the barrel.
- Inconsistent results: Double-check your firearm is securely held and that there is no movement during sighting.
Conclusion
A laser bore sighter is a valuable tool for quickly and easily zeroing your firearm. By following these instructions and prioritizing safety, you can efficiently achieve a near-perfect zero, saving you time and ammunition at the shooting range. Always remember that range verification is essential to guarantee accurate shooting.
