Boar Green Boresight is a green-laser firearm sighting accessory marketed as a tool for helping users align an optic with a firearm's bore before live-fire confirmation. The product is designed around a visible green laser and is promoted for use with different firearm platforms and calibers.
For buyers considering this type of accessory, the main attraction is convenience. A boresight can provide a visual reference during the initial sight-alignment process, potentially reducing the amount of ammunition and range time needed before final confirmation.
What Is Boar Green Boresight?
Boar Green Boresight is a laser-based bore-sighting device associated with MCG Tactical. It is designed to provide a visible laser reference that can be used when aligning firearm sights or optics. Available product information describes compatibility with a broad range of firearm calibers through interchangeable adapters.
The green laser is one of its main selling points. Green light is generally easier for the human eye to see than red light under many indoor and lower-light conditions, which can make a visual alignment tool easier to observe.

How Does Boar Green Boresight Work?
The basic concept is straightforward: the device provides a laser reference corresponding approximately to the firearm's bore direction, allowing the user to compare that reference with the sight or optic.
However, a boresight is not the same thing as a confirmed firearm zero. Actual projectile trajectory is affected by ammunition, barrel characteristics, optic height, distance, and other factors. Independent review coverage also emphasizes that final alignment still requires appropriate confirmation rather than relying solely on the laser.
Key Features
Green Laser: The green beam is intended to provide a highly visible reference point and can be easier to see than many red-laser alternatives in suitable lighting conditions.
Multi-Caliber Compatibility: Available descriptions advertise interchangeable adapters intended to accommodate a broad selection of calibers and firearm types.
Compact Design: The device is designed as a relatively small accessory that can be stored and transported with other range or firearm-maintenance equipment.
Reusable System: Unlike disposable visual alignment methods, the electronic boresight can be used repeatedly when checking or setting up compatible firearms.
Time-Saving Concept: The primary purpose is to provide an initial visual alignment reference before proper live-fire confirmation, potentially reducing unnecessary ammunition use.
Potential Benefits
Boar Green Boresight is primarily aimed at convenience and preliminary sight alignment. Its green laser may be particularly useful where visibility is important, while the multi-caliber concept can make it attractive to owners who work with more than one compatible firearm.
Potential advantages include:
- Clear green laser visibility
- Broad compatibility depending on the adapter set
- Convenient preliminary sight alignment
- Potential reduction in unnecessary ammunition use
- Useful for checking optic alignment after changes
- Compact and reusable design
These benefits describe the intended function of the product and should not be interpreted as a guarantee of accuracy or final zero.

Customer Reviews
Online reviews generally highlight the green laser's visibility and the convenience of using a boresight before heading to the range. Some reviewers report that it helped them get closer to their desired sight alignment before making final adjustments.
At the same time, some review sources mention limitations involving visibility in bright outdoor conditions and the importance of consistent device fit. These observations reinforce the point that a laser boresight should be treated as an alignment aid rather than a substitute for proper firearm verification.
Safety Considerations
A laser boresight should always be treated as firearm equipment and handled responsibly. The firearm should be completely unloaded and handled in accordance with the manufacturer's safety instructions and applicable local laws before any inspection or maintenance activity.
The laser itself should never be directed toward people, vehicles, aircraft, or other inappropriate targets. Users should also follow the manufacturer's instructions for the specific model and adapter configuration.
Pricing & Where To Buy
Online sources show significantly different prices for Boar Green Boresight, with some current listings advertising promotional pricing in the approximate $45–$55 range. Prices, package contents, and guarantees can change, so buyers should verify the current offer before purchasing.
Before ordering, check the exact model, included adapters, warranty or return policy, seller information, and compatibility with the equipment for which the product is intended.
FAQ
What is Boar Green Boresight?
Boar Green Boresight is a green-laser bore-sighting accessory designed to provide a visual reference for preliminary firearm sight or optic alignment.
Why is the laser green?
Green lasers are generally easier for the human eye to detect than red lasers under many lighting conditions, which can make the reference point easier to see.
Does Boar Green Boresight replace live-fire zeroing?
No. A boresight provides an initial reference, but proper firearm zero confirmation requires appropriate verification under safe, controlled conditions.
Is Boar Green Boresight compatible with multiple calibers?
Available descriptions advertise multiple interchangeable adapters for different calibers, although the exact compatibility depends on the particular package.
Final Verdict
Boar Green Boresight is positioned as a convenient green-laser alignment accessory for firearm owners who want a visual reference before completing proper sight verification. Its strongest selling points are the green laser, broad advertised compatibility, reusable design, and potential to reduce some preliminary setup time.
Its limitations are equally important. Laser alignment is only a starting reference and cannot account for every factor affecting actual projectile impact. Bright outdoor conditions can also reduce visibility, and compatibility and consistent fit are important considerations.
Overall, Boar Green Boresight may be useful as a preliminary alignment tool for compatible equipment, provided it is used responsibly and never treated as a substitute for proper firearm safety procedures and final zero confirmation.
