Accurate shooting requires aligning the rifle’s barrel with the target precisely. By achieving proper sight alignment, you increase the likelihood of hitting your intended target consistently.

Introducing Laser Bore Sights

Laser bore sights are compact devices designed to project a laser beam down the bore of your AR 15, allowing you to align your sights accurately. These devices come in various shapes and sizes but share a common goal: to simplify and enhance the process of sighting your rifle. With a laser bore sight, you can save time and ammunition by quickly aligning your sights before heading to the shooting range.

Choosing the Right Laser Bore Sight for Your AR 15

To ensure optimal results, it’s important to choose the right laser bore sight for your AR 15. Consider factors such as compatibility, ease of use, and accuracy. Look for a bore sight that is specifically designed for the AR 15 platform and offers reliable performance.

Preparing Your AR 15 for Sighting

Before using a laser bore sight, it’s crucial to prepare your AR 15 for the sighting process. Ensure that your rifle is unloaded and the chamber is clear. Additionally, secure your firearm in a stable position, such as using a gun vise or a rest, to minimize movement during the sighting process.

Safety First

Always prioritize safety when handling firearms. Double-check that your AR 15 is unloaded and follow proper safety protocols throughout the sighting process.

Mounting the Laser Bore Sight

Choose the appropriate caliber-specific laser bore sight for your AR 15. Align the bore sight with the barrel, ensuring a snug fit. Most lasers bore sights feature a magnetic base or adapters that simplify the mounting process.

Adjusting the Windage and Elevation

Activate the laser bore sight and observe where the laser beam aligns with your target. Using the adjustment knobs on the sight, make windage (horizontal) and elevation (vertical) adjustments until the laser aligns with your desired point of impact.

Checking the Alignment

Without adjusting the rifle’s sights, look through the scope or sights to verify if the laser aligns with the target. If necessary, fine-tune the windage and elevation adjustments until the laser is centered on the target.
