The SSI Sight-Rite laser bore sighting system is a caliber-specific tool built to get your rifle on target fast—without firing a shot. If you're setting up a new rifle, switching optics, or confirming zero after a hunt, this laser bore sighter saves time and ammunition by aligning your scope to your barrel before you ever hit the range. SME engineered separate versions for .243 Win, 7mm-08, and .308 Win, each machined to factory-exact tolerances for the cartridge you're running.

Bore sighters work by projecting a laser beam down your barrel to establish a reference point on a distant target or wall. From there, you dial your scope's reticle to match the laser's dot, giving you a mechanical zero that gets you close enough to start working up a proper sight-in from a safe shooting distance. It's a straightforward process that beats guessing and wastes far less ammunition than traditional cold-bore zeroing.

The Sight-Rite uses a precision-machined brass casing and includes three alkaline button-cell batteries, so you're ready to go out of the box. Since it's caliber-specific, make sure you're ordering the version that matches your rifle's cartridge—there's no universal fit here, and that precision is exactly what keeps the sighter accurate across different case sizes.
