Short description
This 8 mm cartridge-style red laser bore sighter fits into the chamber like a cartridge and projects a precise red dot aligned with the bore axis. Housed in a solid brass shell with a shock-proof precision laser module, it helps you quickly get on paper so you can make coarse adjustments to scopes or sights before live-fire fine tuning.

How to use (quick)

1. Verify the firearm is unloaded and pointed in a safe direction.

2. Install/check the included batteries and close the cap to power the unit.

3. Insert the boresighter fully into the chamber and gently close the action (do not chamber like a live round).

4. Place a target between 15–100 yd (25 yd recommended to get on paper).

5. Adjust windage/elevation until the point-of-aim matches the laser dot.

6. Remove the boresighter and perform live-fire confirmation and final tuning.
