How to Use a Laser Boresighter
Laser boresighters are helpful tools to calibrate a scope for a firearm. Many of the models of laser boresighters are universal, meaning that with the proper adapter, the boresighter can accommodate calibers from .22 caliber all the way up to .50 caliber as well as 20 gauge and 12 gauge shotguns.
Instructions

1
Remove the screw on the back of the laser boresighter and insert the best adapter for the caliber of your rifle.
-
2
Tighten the screw so the adapter fits snugly in the barrel and slide the boresighter all the way up to the end.

-
3
Turn the laser on.
-
4
Aim the rifle at a stationary target, ideally at 50-100 meters.
-
5
Look though the scope and adjust the elevation and windage until the crosshairs are centered on the red dot.
-
6
Remove the boresighter and turn the laser off.
-
7
Take the rifle to a range to complete calibrations. Fire several rounds downrange and make any necessary adjustments to the scope in order to properly zero your rifle.
-
8
Make sure the rifle is unloaded and place the boresighter in the end of the barrel. Point the rifle at your target and note the position of the dot in relation to the scope crosshairs. This will give you an idea of where to adjust your scope should you need to zero the rifle again.

Tips & Warnings
Always remember to take the boresighter out of the barrel before firing the rifle at the range. Failure to do so can result in serious damage to both the rifle and the boresighter.
