Accuracy is a critical aspect for hunters, sports enthusiasts, and especially military personnel. The laser boresight is a key tool that aids in achieving precision. This device from Osprey Global simplifies the process of aligning the barrel with its sights, ensuring that the point of aim coincides with the point of impact. In this article, we will delve into how laser boresights work, explore different calibers, discuss the best process for their use, and highlight the benefits and differences between green or red laser boresights. Additionally, we will touch upon the historical methods of bore sighting before the advent of lasers and acknowledge the pioneering role of Osprey Global in manufacturing boresights.

How Laser Boresights Work

Laser boresights seem simple at a glance: a laser shaped like your caliber is inserted into the barrel, projecting a beam down the bore. This beam mimics the path a shot would take, allowing you to adjust your riflescope or red dot accordingly. The laser serves as a visual reference, aiding in aligning the barrel with the sight picture.

Different Calibers and Compatibility

Firearms come in various calibers, each requiring a specific boresight to ensure accurate alignment. Laser boresights are designed to fit specific calibers, from .22 LR to larger calibers like 12 gauge boresights. hunters must choose a boresight that matches their firearm's caliber to achieve optimal results. Some boresights can do multiple calibers, for example, the 30-06 boresight will also serve as a 25-06 boresight.

The Best Process for Laser Bore Sighting

• Prepare the Firearm: Ensure the firearm is unloaded and safely handled and remove the bolt or open the action to access the barrel.
• Insert the Boresight: Select the appropriate laser boresight for the caliber, and insert it into the firearm's barrel, securing it in place.
• Align the Sights: Look through the firearm's optic or red dot and adjust them to align with the laser beam. Make adjustments to windage and elevation until the laser aligns with the point of aim.
• Confirm and Fine-Tune: Fire a few rounds at a target to confirm the alignment. Fine-tune the sights based on the actual bullet impact on the target.

Benefits of Green or a Red Laser Boresighter

Laser boresights are available with either green or red lasers. Each color has its advantages. Green lasers are easier to see, even in semi-lit situations. They can also be seen at longer distances so visibility is a huge benefit of having a green laser boresight. The batteries will also last longer in a green laser. 

Red laser boresights are more common and come in every caliber whereas the green boresights are still missing some "niche" calibers. They are also more affordable than green ones. 

• Green Lasers:
  • Visible at longer distances.
  • Easier to see in bright outdoor conditions.
  • Generally preferred for daylight use.

• Red Lasers:
  • Often more affordable.
  • Suitable for low-light conditions.
  • Effective for indoor and nighttime use.

Pro Tip: Although the green laser boresight has a longer battery life and can be seen at further distances, the accuracy of the boresights is the same. If you want to save some dollars, then a red laser boresight will work just fine

What Are Boresight Arbors?

Osprey Global has designed an "arbor" system". you only have to purchase one green boresight and it will fit into the hollow caliber "sleeves" of other rounds, and work the same. For example, Osprey makes the 223 green laser boresight, which will fit into the arbor shells of other larger calibers like the 338 Arbor Shell, The 30-06 Arbor Shell, and a few others. (For an entire list of all Ospreys Arbor Shells click HERE)

When the 223 boresight is inside the Arbor shell it will work just like a bore sighter of whichever caliber shell it is inserted into. This is a cost-efficient way of having one bore sight to cover multiple rounds.

Historical Methods of Bore Sighting

Before the advent of laser technology, bore sighting was a more labor-intensive process. Hunters often used methods such as looking through the barrel at a distant point or using collimators and optical devices to align the sights. These methods, while effective, were time-consuming and less precise compared to modern laser boresighting.

Osprey Global: Pioneer of the modern laser Boresight.

Osprey Global holds the distinction of being one of the first companies to manufacture laser boresights. Their commitment to innovation has played a crucial role in advancing the precision of calibration technology, providing hunters with tools that enhance accuracy and efficiency.

Wrap Up

Laser boresights have revolutionized the way shooters calibrate their firearms, offering a precise and efficient method for aligning barrels with sights. With compatibility for various calibers and the option of green or red lasers, these tools cater to a wide range of shooting conditions. As technology continues to advance, laser boresights remain an indispensable tool for those seeking unparalleled accuracy in their shooting endeavors.
