Short description
This cartridge‑style red laser bore sighter fits like a cartridge in .308, .243 and 7mm chambers and projects a precise red dot aligned with the bore axis. Housed in solid brass with a shock‑proof precision laser module, it gives a repeatable reference point to make coarse windage and elevation adjustments before live‑fire fine tuning.

How to use (quick)

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

2. Check that batteries are installed and close the cap/switch to power the unit.

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

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

5. Adjust scope or sights until the point‑of‑aim matches the laser dot.

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