SME XSILBK2 Sight-Rite Muzzle Laser Bore Sight .17-.50 Cal Metal

The SME Sight-Rite XSILBK2 is a muzzle-mounted laser bore sighter designed to work with firearms chambered in calibers ranging from .17 up to .50. Its wide fitment makes it a single bench tool for sighting in rifles, handguns, and muzzleloaders across rimfire, centerfire, and large-bore applications.

Constructed around a metal housing for durability, the unit projects a visible laser dot down the bore so you can zero your scope or red dot quickly without burning through live ammunition. The compact sighter runs on a common LR44 battery, so replacements are easy to source at virtually any shop or range.

The XSILBK2 ships ready to run, with an alignment target for fast bench setup and a storage pouch to keep the laser and included components organized and protected between range sessions.
