Simplify the Sighting-in Process with a Laser Boresighter for Hunting in Alaska

While science fiction often depicts exotic weapons utilizing laser beams, practical engineers have harnessed this technology for outdoor applications that far surpass the capabilities of a light saber.

Before the advent of boresighters, shooters faced a time-consuming and costly process of aligning their riflescopes with the actual point of impact. Traditional methods required multiple shots to align the crosshairs with the bullet’s trajectory. Early boresighters simplified this task, but modern innovations have taken the process to a new level.

Today’s advanced boresighters significantly reduce setup time and offer additional functionalities that are crucial for field conditions. Understanding these tools is essential for any serious hunter.

Prior to high-tech boresighters, options were limited but still effective. Mechanical boresighters utilized specific arbors tailored for each caliber or adjustable for shotguns. After selecting the appropriate arbor, it is inserted into the muzzle, and the boresighter is aligned before heading to the range.

Regardless of the design, a boresighter serves as a tool to get shooters close to their target. Windage and elevation adjustments will still be necessary, but the initial gap will be significantly smaller when starting the sighting process.

There are three primary types of boresighters, each claiming to provide an advantage. These include cartridge lasers that fit into the chamber, muzzle-inserted lasers, and manual units that attach to the barrel’s end without entering the bore.

Cartridge Lasers for Precision

Cartridge lasers have gained popularity for their ease of use. These caliber-specific devices are inserted into the chamber and activated when the bolt is closed. However, for shooters with multiple firearms, this may require purchasing a separate laser for each caliber or gauge.

To mitigate costs, adaptable cartridge lasers are available, allowing users to buy a single base unit and interchangeable caliber cartridges as needed.

Muzzle-inserted Lasers for Versatility

Muzzle-inserted lasers feature either a tapered body or a precisely sized arbor for specific calibers. Models with tapered bodies can be adjusted for various calibers, requiring only the right O-ring for each firearm. While this design is effective, users should be cautious as O-rings can occasionally detach during removal. Checking the O-ring’s attachment before use can prevent issues.

Additionally, consider the combination laser boresighter and Scope Reticle Leveler. Ensuring level crosshairs is critical for accurate scope setup. An improperly leveled scope can cause significant deviations in shot placement, especially at longer distances.

The Scope Reticle Leveler simplifies this process. By securing the firearm in a stable position and aligning the reticle with the projected beam, shooters can confidently proceed with the boresighting process, ensuring precision.

Magnetic Attachment for Universal Fit

The magnetic attachment option offers versatility, fitting any firearm, from rifles to shotguns. For example, the Leupold Zero Point boresighter is user-friendly, accurate, and lightweight, making it suitable for field use.

To use the Zero Point, activate it by sliding the switch on the back. Adjust the vertical height until the grid aligns with the center of the view through the riflescope. Fine-tune the orientation until both vertical and horizontal crosshairs align perfectly. Adjust the elevation and windage knobs to match the grid’s center, preparing for final adjustments.

After removing the boresighter, fire a shot at a blank target from 50 yards. If set up correctly, the shot should land on the paper, albeit not necessarily in the bull’s-eye. Reattach the Zero Point and align its grid with the target’s center. This allows for precise adjustments to ensure the firearm is perfectly zeroed. Noting the scale on the unit enables quick field checks.

A useful technique involves marking where the laser beam falls after achieving tight shot groups. If the laser deviates from this mark during subsequent checks, adjustments can be made quickly and quietly, avoiding unnecessary shots in the field.

This method is especially beneficial in remote hunting locations, where ensuring scope accuracy is crucial without the need for excessive shooting.
