Green Laser bore sighter

Published on March 15, 2023
Duration: 9:12

This video demonstrates the use of a cartridge-shaped green laser bore sighter designed for .223 Remington/5.56x45mm NATO firearms. The presenter highlights its convenience for initial optic alignment but notes its limitations in broad daylight due to low visibility at distance. It's recommended for indoor use or shaded areas at closer ranges, requiring ballistic calculations for zeroing at greater distances.

Quick Summary

A cartridge-style green laser bore sighter fits into your firearm's chamber to project a laser dot for initial optic alignment. While convenient and safe, its visibility is limited in broad daylight at distances over 10-15 yards, making it best suited for indoor use or shaded areas. For precise zeroing, live fire is still required.

Frequently Asked Questions

What is a cartridge-style laser bore sighter?

A cartridge-style laser bore sighter is a device that fits into your firearm's chamber, resembling a live round. When activated, it projects a laser dot, allowing you to roughly align your optic (scope or red dot) with the firearm's barrel without firing a shot.

How do you use a laser bore sighter?

Insert the bore sighter into the chamber, screw on the battery cap to activate the laser, and observe the projected dot. Adjust your optic's reticle to match the laser dot. Remember to use it in shaded conditions or indoors for best visibility, and always ensure the firearm is unloaded.

What are the limitations of a green laser bore sighter?

The primary limitation of compact, cartridge-style green laser bore sighters is their visibility in broad daylight at longer distances. They are most effective indoors or in shaded areas at closer ranges (10-25 yards).

Can a laser bore sighter fully zero a firearm?

No, a laser bore sighter is primarily for initial alignment. It provides a close-range reference point. For precise zeroing, especially at longer distances, live fire is essential to account for bullet trajectory and firearm-specific performance.
