Wheeler Professional Laser Bore Sighter Instruction Manual
Model: 589922
Product Overview
The Wheeler Engineering Professional Laser Bore Sighter is designed for fast and accurate bore sighting of firearms. It utilizes a high-power laser and a strong magnetic connection to the barrel, ensuring precise alignment without damaging the bore. This versatile system is compatible with virtually all firearms, including rifles, shotguns, and handguns. Each unit undergoes a meticulous hand-tuning process with an innovative calibration mechanism to guarantee maximum precision and reliable performance.

Key Features
- Class IIIa Laser: Power output less than 5mW for safe and effective use.
- Magnetic Connection: High-strength magnetic attachment to the muzzle ensures precise alignment and prevents bore damage.
- Universal Compatibility: Works with rifles, shotguns, and handguns.
- Precision Calibration: Hand-tuned during manufacturing for optimal bore/optic alignment.
- Durable Construction: Machined aluminum body with soft rubber over-molding for enhanced grip and protection.
- Compact and Portable: Designed for easy storage and transport.
Setup and Preparation
- Unpack Contents: Carefully remove the Professional Laser Bore Sighter and any included accessories from its storage case.

- Safety First: Ensure the firearm is completely unloaded and clear of any ammunition. Always follow proper firearm safety procedures.
- Stabilize Firearm: Place the firearm securely in a cleaning rest or a stable platform to prevent movement during the bore sighting process. This allows for hands-free operation and precise adjustments.
- Prepare Muzzle: Ensure the muzzle of the firearm is clean and free of debris. If desired, a thin layer of protective tape (e.g., painter's tape) can be applied to the bore sighter's magnet to prevent direct contact with the barrel finish.
- Install Battery: The bore sighter typically uses a CR123A battery. Insert the battery according to the polarity indicators.
Operating Instructions
Follow these steps to effectively use your Professional Laser Bore Sighter for optic alignment:
- Attach Bore Sighter: Gently bring the bore sighter to the muzzle of the firearm. The strong magnet will secure it in place. It is recommended to approach at a slight angle and ease it onto the barrel to avoid a hard snap. Ensure the bore sighter is as centered as possible on the muzzle.

- Activate Laser: Turn on the laser on the bore sighter. A bright laser dot will project from the muzzle.

- Set Up Target: Place the included reflective target (or a suitable alternative) at a desired distance. For initial bore sighting, a distance of 15-25 yards (or meters) is often recommended. Position the target so the laser dot is visible on it.
- Align Optics: Look through your optic (scope, red dot sight, iron sights). Adjust the windage (horizontal) and elevation (vertical) turrets of your optic until its reticle or aiming point aligns precisely with the laser dot projected by the bore sighter on the target.

- Verify Alignment: Once aligned, carefully remove the bore sighter. The firearm is now bore sighted and should be "on paper" at your chosen distance, significantly reducing the number of live rounds needed for final zeroing at the range.
Note: Bore sighting is an initial alignment process. Final zeroing should always be performed at a shooting range with live ammunition to account for bullet drop and other ballistic factors specific to your firearm and ammunition.
Maintenance
- Cleaning: After each use, wipe down the bore sighter with a clean, dry cloth to remove any dust, dirt, or residue. Avoid using harsh chemicals or abrasive materials that could damage the finish or optical components.
- Storage: Store the bore sighter in its original case or a protective pouch when not in use. Keep it in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: If the laser appears dim or flickers, replace the CR123A battery. Always dispose of used batteries responsibly.
- Magnetic Surface Care: Periodically inspect the magnetic surface for any embedded debris that could scratch your firearm's muzzle. Clean as necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser is dim or not turning on. | Low or dead battery; incorrect battery insertion. | Replace the CR123A battery, ensuring correct polarity. |
| Bore sighter does not attach securely to muzzle. | Muzzle device is made of non-ferrous material (e.g., aluminum alloy); debris on magnetic surface. | Ensure the muzzle or muzzle device is magnetic. Clean the magnetic surface of the bore sighter. |
| Laser dot is difficult to see. | Bright ambient light; long distance to target. | Use in lower light conditions or at shorter distances. Utilize the included reflective target for better visibility. Green lasers are generally more visible in daylight than red lasers. |
| Bore sighter seems off-center. | Improper attachment to muzzle. | Ensure the bore sighter is seated as centrally as possible on the muzzle. While perfect centering is ideal, the magnetic connection provides sufficient stability for initial bore sighting. |
