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.[1]
