Short description
This .338 Lapua cartridge laser bore sighter is machined from aluminum and finished in red anodize for a professional look and durable performance. Insert into the chamber to project a precise red dot aligned with the bore axis. Ideal for coarse zeroing of scopes, red dots and iron sights at ranges between 15 and 100 yards — saves ammo and speeds up sighting sessions.

How to use (quick)

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

2. Check/insert batteries and screw the cap to power the unit (if applicable).

3. Insert the boresighter into the .338 Lapua 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/elevation until the point‑of‑aim matches the laser dot.

6. Remove the unit and verify zero with live shots.
