Short description
This .300 Blackout cartridge-style red laser bore sighter slips 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 get on paper fast so you can make coarse adjustments to scopes or sights before live-fire fine tuning.

How to use (quick)

1. Verify 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 .300 Blackout chamber and gently close the action (do not chamber like a live round).

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

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

6. Remove the boresighter and confirm zero with live-fire shots.
