The Sightmark Laser Boresight provides a fast, accurate, and user-friendly method for sighting in rifles and shotguns. Chamber the boresight like a standard cartridge and the laser projects a precise dot onto your target - allowing you to adjust scopes, red dots, and iron sights without firing a single shot. This approach saves ammunition, shortens range time, and gets you on paper quickly so you can reserve live fire for final tuning and distance compensation.Perfect for hunters prepping for the season, competitive shooters dialing in a new optic, or law enforcement maintaining equipment, the Sightmark boresight streamlines the sight-in process. A lightweight protective pouch keeps the unit safe in the field, and its straightforward operation makes it accessible to beginners while still being a useful tool for experienced shooters. Use the Sightmark Laser Boresight to spend less time zeroing and more time improving your shooting. Purchase yours at AR-15 Discounts.
