SME Sight-Rite Laser Bore Sighting System 270 WSM / 7mm WSM / 300 WSM / 325 WSM Brass Cartridge

The SME Sight-Rite laser bore sighter is a caliber-specific, cartridge-style alignment tool purpose-built for the Winchester Short Magnum family, covering 270 WSM, 7mm WSM, 300 WSM, and 325 WSM chambers. It drops into the action like a live round so you can square up a scope or iron sights quickly without burning a single box of ammunition.

Each Sight-Rite is precision machined from a solid brass casing to exacting tolerance specifications, producing a high-output laser that travels straight down the bore and shows you exactly where the barrel is pointed. The caliber-specific fit seats squarely in the chamber for a true representation of point of impact relative to your optic, making scope mounting and zeroing a much faster, more controlled process.

Powered by three included LR754 button cell batteries, the Sight-Rite is ready to use right out of the package. Whether you are setting up a new WSM-chambered rifle, swapping optics between rifles, or verifying zero at the bench, this brass cartridge-style bore sighter is a shop and range essential that saves both time and money over the traditional sight-in workflow.
