The Sightmark Universal Laser Boresight uses a 532nm green laser and magnetic mounting system to assist with sight alignment on rifles, pistols, and shotguns. Its aluminum housing weighs just 3 ounces, while a 15-to-150-yard sighting range, magnetic base with arbor, and included CR2 battery provide convenient firearm setup.
The Sightmark Universal Laser Boresight provides a convenient way to perform preliminary sight alignment across a broad range of firearms. Rather than requiring a caliber-specific chamber insert, this model uses a magnetic base with arbor and is designed to work with rifles, pistols, and shotguns.
The boresight uses a 532nm green laser with a specified sighting range of 15 to 150 yards. At 100 yards, the projected laser dot measures approximately 2 inches, providing a clearly defined reference during the alignment process.
By projecting a visible point along the firearm's bore direction, the Sightmark boresight can assist with initial optic or sight setup before final confirmation through live-fire zeroing.
A magnetic base with arbor allows the unit to attach without requiring a caliber-matched cartridge-style boresight. This universal approach makes the tool practical for owners who need to work with several different rifles, pistols, or shotguns.
The unit measures 5.7 inches by 1.1 inches and weighs 3 ounces. Black aluminum construction keeps the housing lightweight while providing a durable foundation for repeated setup and storage.
Power comes from one CR2 battery, which is included with the boresight.
The Sightmark Universal Laser Boresight stands out for its broad firearm compatibility and simple magnetic attachment. Its green laser, 15-to-150-yard sighting range, lightweight aluminum housing, and included battery make it a practical tool for preliminary sight and optic alignment without maintaining multiple caliber-specific boresights.
