Sightmark 12 gauge Premium Laser Boresight

The Sightmark 12 gauge Premium Laser Boresight is an essential tool for any shotgun owner looking to streamline their zeroing process and save on expensive ammunition costs. This device is particularly useful for those setting up a home defense shotgun with a new red dot or prepping a slug gun for hunting season, providing a reliable reference point without the need for immediate live fire.

Functioning by being chambered directly into your firearm like a standard shell, the Sightmark 12 gauge Premium Laser Boresight ensures the laser emitter is perfectly centered within the barrel for maximum accuracy. It projects a visible red dot onto a target downrange, allowing you to adjust windage and elevation settings to match the actual trajectory of the bore. This internal chambering method is more reliable than universal external boresights that can shift or cant when attached to the muzzle.

Tactical professionals and enthusiasts alike will find the Sightmark 12 gauge Premium Laser Boresight indispensable for verifying zero after travel or maintenance. Its ease of use and effectiveness make it a valuable addition to any shotgun owner's toolkit, ensuring that optics or bead sights are aligned before heading to the range.
