What Is Boar Green Boresight?
The Boar Green Boresight represents one of the latest entries in the precision firearms alignment market, offering shooters a method to align their sighting systems without firing a single round. Debuting approximately three years ago, this tool quickly gained attention among firearms enthusiasts for its distinctive green laser technology and claims of superior accuracy compared to traditional red laser boresights.
At its core, the Boar Green Boresight is a precision-machined device that inserts into a firearm's chamber or muzzle (depending on the model), projecting a bright green laser dot that represents the theoretical path of the bullet. This allows users to align their optics or iron sights with the weapon's bore axis without the expense and time commitment of live-fire zeroing.
The manufacturer, BoarOptics Inc., entered the shooting accessories market in 2015 after its founder, former military armorer Thomas Keller, identified what he considered significant shortcomings in existing boresighting solutions. The company operates from its headquarters in Phoenix, Arizona, where they claim to combine military-grade quality control with innovative optical engineering. Before launching the Green Boresight series, BoarOptics established a moderate reputation with their line of rifle scopes and red dot sights, primarily serving the tactical and competition shooting communities.
While relatively new compared to established industry names like Sightmark or Wheeler, BoarOptics has aggressively marketed their green laser technology as a revolutionary improvement in boresighting precision. This has generated significant buzz in online forums and social media groups focused on firearms and accessories.
The Boresighting Process Explained
Boresighting is a preliminary alignment procedure that establishes an initial relationship between a firearm's bore axis and its sighting system. Unlike the definitive process of zeroing—which involves actual firing and sight adjustment based on impact points—boresighting serves as a critical first step that significantly reduces ammunition waste and shooter frustration during the final zeroing process.
Install Boresight
Insert the device into the chamber or attach to the muzzle, ensuring proper fit for your specific caliber
Project Laser
Activate the laser to project a reference point on a target at your desired distance
Adjust Sights
Modify your optic or iron sight settings to align with the laser point
Verify Alignment
Confirm alignment from a stable position before proceeding to live-fire confirmation
The primary benefit of proper boresighting lies in its efficiency. By establishing a reasonably close alignment before firing, shooters typically require significantly fewer rounds to achieve their final zero—often reducing a 10-15 round process to just 3-5 confirmation shots. This not only saves ammunition costs but also reduces barrel wear and shooting fatigue, particularly important considerations when working with high-recoil calibers or when sighting in multiple firearms during a single session.
Beyond initial sight-in procedures, boresighting serves valuable secondary purposes. It provides a quick verification method to check for potential sight movement after transportation or rough handling. For hunters in remote locations, a boresight offers a field-expedient way to confirm optic alignment before crucial shots. Competition shooters and tactical professionals also use boresighting as part of regular equipment checks to ensure their sighting systems remain true to their established zeros.
While boresighting cannot replace the necessity of live-fire confirmation, the process has become an essential practice for conscientious firearm owners seeking precision without excessive ammunition expenditure. The accuracy of this preliminary alignment directly impacts the efficiency of the subsequent zeroing process, which explains the premium placed on boresight quality and performance.
Spotlight on "Green" Technology
The distinction between red and green laser technology represents more than a simple color preference—it involves fundamental differences in wavelength properties, visibility characteristics, and practical applications for shooters. The Boar Green Boresight builds its marketing primarily around these differences, claiming superiority over traditional red laser systems used in competing products.
Red Laser Technology
Traditional red lasers operate at wavelengths between 630-670 nanometers, pla
