Boresighters

Boresighters

Boresighting is a method of visually pre-aligning a firearm barrel's bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle and can be accomplished either with the naked eye, or with a specialized device called a boresighter. Here you can find both laser and analog boresighters by brands such as Nikko Stirling and Sightmark.
