Accurate zeroing is crucial for any firearm, and using a bore sighter laser can significantly speed up the process and save you ammunition. This guide will walk you through how to properly and safely use a bore sighter laser to get your firearm on target before hitting the range.
What is a Bore Sighter Laser?
A bore sighter laser is a small device that fits into the barrel of your firearm. It projects a laser beam through the barrel, allowing you to quickly and easily align your sights or scope with the bore axis. This eliminates the need for extensive live fire to find your zero point, saving you time and ammunition.
Types of Bore Sighters
There are several types of bore sighter lasers available, including:
- Self-contained units: These are all-in-one units with the laser built-in. They are easy to use and relatively inexpensive.
- Modular systems: These allow for interchangeable adapters to fit various firearm calibers. They may require slightly more assembly but offer greater versatility.
Regardless of the type you choose, ensure it’s compatible with your firearm's caliber.
Step-by-Step Guide to Using a Bore Sighter Laser
Safety First! Always treat every firearm as if it were loaded. Never point a firearm at anything you don't intend to shoot.
-
Preparation:
- Unloading the Firearm: Ensure your firearm is completely unloaded and the magazine is removed. Visually and physically inspect the firearm to confirm it's unloaded.
- Safe Environment: Choose a safe environment, ideally an outdoor range or a designated shooting area. Ensure there are no obstructions in the path of the laser beam.
- Assembly (if necessary): Follow the manufacturer's instructions to assemble your bore sighter laser if it's a modular system. Ensure it's securely fitted into the adapter.
-
Inserting the Bore Sighter:
- Careful Insertion: Carefully insert the bore sighter laser into the barrel of your firearm. Avoid forcing it; a snug fit is sufficient. Ensure the laser emitter is facing the muzzle end.
- Proper Seating: Make sure the bore sighter is seated correctly and is not obstructing the barrel.
-
Activating the Laser:
- Battery Installation: If needed, install the required batteries (usually included).
- Turning it On: Turn on the laser according to the manufacturer's instructions.
-
Aiming and Adjusting:
- Target Placement: Place a target at a suitable distance (typically 25 yards or 25 meters).
- Sight Adjustment: Use the laser beam as a reference point to adjust your sights or scope to the point of aim on the target. You may need to make minor adjustments to achieve perfect alignment. Remember, the laser will show you where the bullet will go at a particular distance.
-
Removal and Clean Up:
- Removing the Bore Sighter: Carefully remove the bore sighter from the barrel.
- Cleaning: Clean the barrel as usual to remove any potential debris.
Tips and Considerations
- Distance Matters: Remember the bore sighter laser gives you a point of aim at a specific distance. You’ll still need to fine-tune your zero at the range with live ammunition, especially at longer distances.
- Variations: There can be slight variations between the laser beam and the actual bullet trajectory due to factors like rifling and bullet weight.
- Proper Maintenance: Keep your bore sighter clean and properly stored when not in use.
- Calibration: Some high-end bore sighters offer adjustable features. Consider the need for calibration as you use the device with more firearms and calibers.
Conclusion
Using a bore sighter laser can drastically improve the efficiency of your zeroing process, saving you time and ammunition. By following these steps and safety precautions, you can confidently use a bore sighter laser to get your firearm on target before you begin shooting live rounds. Remember to always prioritize safety and consult your firearm's manual for specific instructions.
