Sightmark Trpdty Universal Boresight

The Sightmark Triple Duty Universal Boresight is a red laser bore-sighting tool designed for quickly and accurately zeroing firearms, specifically .17 through .50 caliber rifles, shotguns, and pistols without the need to fire ammunition. This tool is ideal for those who require precision in their shooting practices, including hunters and recreational shooters.

The boresight features a self-centering arbor that inserts into the barrel's end, preventing metal particles from entering the bore. This design eliminates the need for multiple adapter sleeves, reducing the risk of losing parts in the field. Its compact design makes it easy to transport in tactical packs or range bags.

The Sightmark Triple Duty Universal Boresight is particularly beneficial for users managing mixed firearm inventories, as it simplifies the zeroing process for various calibers. It accelerates the initial zeroing of newly mounted optics and helps verify zero after transport or duty rotation, enhancing shooting accuracy.
