SME Sight-Rite Laser Bore Sighter 9mm Luger Brass Casing

The SME Sight-Rite Laser Bore Sighting System is a caliber-specific alignment tool built for 9mm Luger chambers. Precision-machined from a real brass casing, this bore sighter drops into the chamber of your handgun and delivers factory-aligned laser output, letting you zero a slide-mounted optic or scope without firing a single round.

A high-output red laser projects a tight point downrange so you can confirm sight alignment on a target or wall at home or on the range. Because the brass body matches true 9mm Luger case dimensions, the Sight-Rite seats concentrically in the bore and holds the laser centered on the gun's axis - eliminating the wobble and misalignment common with universal-fit boresights and giving you a clean starting point for optic mounting.

The unit is powered by three included LR41 alkaline button-cell batteries, so it is ready to use right out of the package. Its compact, cartridge-shaped form tucks easily into a range bag or toolbox, and the rugged brass construction holds up to repeated chambering. The SME Sight-Rite is ideal for initial optic mounting, confirming zero after a sight swap, or a quick pre-range check on any 9mm Luger handgun.
