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. This allows you to precisely align your sights—whether iron sights, red dot, or shotgun-specific optics—with the bore's true axis in minutes. The cartridge-based design means no batteries to manage during critical maintenance windows, and the compact 3.8 x 1.5 x 7.45-inch form factor fits easily in any range bag or duty gear locker. At just 0.25 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. This tool is compatible with any 12-gauge shotgun—pump, semi-automatic, or break-action—making it an essential addition to department armories and training facilities. Shooters can zero from 7 to 25 yards depending on room availability, and the laser remains visible even in moderately lit indoor ranges. For duty weapons qualifications, transition training, or pre-deployment preparation, the SME Sight-Rite eliminates point-of-aim offset before live fire, saving both ammunition costs and training time.
