Boresighting your rifle is a crucial first step in achieving accuracy. It allows you to quickly and easily align your sights with the barrel's bore, significantly reducing the time spent at the range zeroing your weapon. Using a boresighting laser is a particularly efficient and cost-effective method. This guide provides a step-by-step process for boresighting your rifle with a laser, covering essential considerations and safety precautions.
Understanding Boresighting: Why and When
Before diving into the how-to, let's understand the why. Boresighting isn't about achieving perfect accuracy; that's the job of zeroing at the range. Instead, it's about getting your sights close enough to the target that you can make adjustments during your zeroing process. This saves you ammunition, time, and frustration. Boresighting is particularly helpful when:
- You've installed new sights: After mounting a new scope or iron sights, boresighting aligns them with the barrel, providing a starting point for zeroing.
- You've disassembled and reassembled your rifle: If your rifle has been taken apart, boresighting ensures that the alignment hasn't been disturbed.
- You're using a new firearm: A quick boresight check can reveal significant alignment issues before you even reach the range.
Equipment You'll Need
To boresight your rifle with a laser, you'll need the following:
- A laser boresight: Choose a boresight compatible with your rifle's caliber. Ensure it's designed for the specific type of firearm you own (e.g., AR-15, bolt-action, etc.).
- Your rifle: Make sure your rifle is unloaded and that you've followed all safe firearm handling procedures.
- A stable shooting rest (optional but recommended): This will provide a more consistent and accurate boresighting process.
- Eye protection: Always wear eye protection when handling firearms and laser devices.
- Target: A suitable target at a reasonable distance (25-50 yards is usually sufficient).
Step-by-Step Guide to Boresighting Your Rifle
Safety First: Before beginning, always ensure your firearm is unloaded and clear. Double-check the chamber and magazine to confirm it is completely safe.
-
Prepare Your Rifle: Ensure your rifle is clean and free from obstructions.
-
Insert the Laser Boresight: Carefully insert the laser boresight into the barrel of your rifle. Follow the manufacturer's instructions precisely. Ensure it's seated correctly and firmly.
-
Secure Your Rifle: Position your rifle on a stable rest or hold it firmly and steadily.
-
Aim at the Target: Aim your rifle at your target, focusing on the laser's point of impact. Adjust your rifle's position to center the laser dot on the target. This may require minor adjustments to elevation and windage.
-
Adjust Your Sights: Once the laser is centered on the target, carefully remove the boresight. Now, adjust your rifle's sights (scope or iron sights) to match the laser's point of impact. This step requires meticulous attention to detail.
-
Verify Alignment: Once you've adjusted your sights, you can (optionally) reinsert the laser boresight to double-check your work before heading to the range.
-
Proceed to Zeroing at the Range: While boresighting gets you close, you will need to fine-tune your sights by zeroing at the range using live ammunition.
Tips for Accurate Boresighting
- Use a stable shooting rest: A stable rest minimizes movement and improves accuracy.
- Maintain proper eye relief: Ensure proper eye relief with your scope to avoid eye strain and improve accuracy.
- Work in a well-lit environment: Sufficient lighting makes it easier to see the laser dot on the target.
- Choose a suitable target: A clear and contrasting target helps in accurate alignment.
- Take your time: Rushing the process can lead to errors. Be patient and methodical.
Conclusion: Boresighting for Enhanced Accuracy
Boresighting your rifle using a laser significantly improves your efficiency in achieving accuracy. It's a vital preliminary step, saving you time and ammunition at the range. Always prioritize safety and adhere to responsible firearm handling procedures. Remember that boresighting is just the first step; accurate zeroing at the range with live fire is always necessary to achieve optimal shooting performance.
