<p data-pm-slice="1 1 []"> The Boar Green Boresight is a very accurate tool made to help people who use guns line up their sights or scopes quickly and correctly without even shooting.



It gives off a bright green laser beam from the middle of the barrel. This lets the shooter line up their optics or iron sights with the place where the laser hits.



Chamber-inserted and muzzle-inserted are the two main types. The chamber model fits like a cartridge, but the barrel version has adapters that can be used with different calibers.



Once the laser is turned on, it gives you a way to see how to change the windage and elevation on your optics. This makes the process of getting your scope "zeroed" faster and better.
