Sme Sight-rite Cartridge Laser - Bore Sighter 12ga

The SME Sight-Rite Cartridge Laser Bore Sighter for 12ga is a precision zeroing tool designed for law enforcement, military personnel, and serious shotgun shooters who demand repeatable accuracy. This compact laser bore sighter eliminates guesswork at the range by projecting a visible laser down the barrel, allowing shooters to align their sights without firing a single round.

Whether you're sighting in a tactical shotgun for duty use, preparing for training evolutions, or maintaining a home-defense firearm, this tool dramatically reduces ammunition waste and accelerates the zeroing process. The Sight-Rite operates on a simple but effective principle: insert the laser cartridge into the 12-gauge chamber, and it emits a laser beam along the barrel's centerline, allowing you to precisely align your sights.

This cartridge-based design means no batteries to manage during critical maintenance windows, and its compact form factor fits easily in any range bag or duty gear locker. At just 0.2 lbs, it adds negligible weight while delivering professional-grade sight alignment capability. Law enforcement armorer teams, military instructors, and gunsmith professionals rely on bore sighters to verify shotgun zero during issued-firearm maintenance cycles.
