Laser bore alignment for 12-gauge shotguns

Chamber-mounted boresighting eliminates guesswork when aligning your shotgun's sights or optics. The Sightmark laser projects a dot down the barrel, letting you confirm your sight picture without firing. This method works indoors or at the range, cutting ammunition waste significantly. For shooters buying used shotguns or setting up new optics, boresighting is a practical first step. If you're transferring a shotgun through private party transfer process, boresighting ensures you're ready to shoot safely. Visit our gun shop in Sunnyvale for our full catalog.

Frequently asked questions

How does a chamber-mounted boresighter work on a shotgun?

The boresighter inserts into the chamber and projects a laser beam down the barrel. You align your sights or scope to the laser dot at a known distance, establishing your zero without firing.

Can I use this boresight with shotgun optics and red dots?

Yes. The laser reference works with any sight mounted on your 12-gauge—bead sights, slug scopes, or red dot systems. Align each optic to the laser beam independently.
