Sightmark Triple Duty Universal Boresight Red Laser Multi-Caliber .17-.50

The Sightmark Triple Duty Universal Boresight is a red-laser sighting tool designed to speed up the initial sight-in of .17 to .50 caliber rifles, shotguns, and pistols. Built around a magnetic muzzle attachment, the unit centers itself in the bore without arbors or adapter inserts, giving it true multi-caliber versatility in a single compact device.

The housing is machined from aluminum for light weight and durability on the bench or in the field. Power is supplied by three AG13 cell batteries (included), driving a steady red laser dot down the bore for fast, visible alignment with the host firearm's optic or iron sights.

Whether you are zeroing a rimfire, centerfire rifle, handgun, or shotgun, the Triple Duty Universal Boresight eliminates the trial-and-error of live-fire adjustment and lets you get on paper quickly. The package ships with the boresight, the battery pack, and a carrying case for protected storage between range sessions.
