SME Sight-Rite XSIBL17 Laser Bore Sighter 17 HMR Brass Casing

The SME Sight-Rite XSIBL17 is a laser bore sighter chambered for 17 HMR, purpose-built to dial in optics on rimfire rifles without firing a shot. Precision machined from a real brass casing for an exact chamber fit, this cartridge-style tool drops into the action and projects a high-output red laser downrange so you have a true reference point for adjusting scope windage and elevation.

Operation is straightforward: insert the brass sighter like a round, close the bolt, and let the laser dot guide your adjustments. Powered by three button cell alkaline batteries (included), the SME Sight-Rite lets you mount and zero optics quickly at the bench, saving range time, ammo, and frustration.

Designed for chamber-mount use in any standard 17 HMR rifle, this SME Sight-Rite is a practical sighting-in tool for any rimfire shooter.
