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.
