Instructions for a Bushnell Laser Boresighter

Overview
Laser boresighters provide an essential tool for gunsmiths and shooters to quickly and accurately get a gun sighted in. They are the first step to accurate shooting and can save the shooter money by reducing the amount of shooting at the range. There are many types of boresighters available for a custom fit, but the Bushnell Laser Boresighter is a unique tool that fits a wide range of guns with a quick change of a screw.
Initial Setup
Install 3 LR 44 batteries and turn the boresighter on with the on/off switch located on the top of the boresighter. Make sure you can see the small red laser dot being emitted from the end of the boresighter.
Using the Boresighter
Find the properly sized adapter by finding the largest adapter that will fit in the muzzle of the gun. There are five sizes included with the Bushnell Laser Boresighter, ranging from .22 to .50 caliber. Screw the adapter to the small end of the boresighter and insert into the muzzle. Point the red laser at the target and look through the crosshairs in the scope. Adjust the windage and elevation settings on the scope until the crosshairs line up with the laser.
