Sightmark Triple Duty Universal Green Laser Bore Sight .17-.50 Cal

The Sightmark Triple Duty Universal Green Laser Bore Sight is a fast, accurate tool for initial scope and sight zeroing on rifles, shotguns, and handguns. This green laser boresight projects a visible aiming point downrange so you can confirm and adjust your optic without burning through live-fire ammo.

Built around a rugged aluminum housing with a magnetic base, the Triple Duty Universal attaches directly to the muzzle end of the barrel, eliminating the need for arbors or caliber-specific inserts. The unit supports a wide range from .17 to .50 caliber and 12 Gauge, making it a true multi-caliber tool for the range bag or gun bench.

Powered by a single CR2 battery, this 5 mW green laser is rated for effective sighting at ranges of 15 to 100 yards. Its compact, lightweight design makes it easy to carry in a range kit, and the universal fit lets you move quickly between firearms in your collection.

Whether you're zeroing a new red dot, dialing in a magnified optic, or roughing in iron sights, the Sightmark Triple Duty Universal Green Laser Bore Sight is a smart, reusable alternative to traditional arbor-style boresights and the cost of repeated short-range live-fire zeroing.
