Sitelite Ultra Mag Green Laser Boresighter

The Sitelite Ultra Mag Green Laser Boresighter is a precision bore-zeroing tool engineered for law enforcement, military, and civilian shooters who demand accuracy across multiple platforms. Whether you're running duty rifles, patrol carbines, pistols, or shotguns, this boresighter eliminates guesswork from the initial sight-in process—a critical step that saves ammunition and range time. The ultra-bright XP green laser technology provides daylight-visible beam projection on targets from short to extended distances, making it invaluable for gunsmiths, armorer teams, and individual operators standardizing multiple firearms.

Built with a long-life lithium battery and integrated scope reticle leveler, the Sitelite Ultra Mag uses ballistic targeting software to calculate drop compensation across caliber ranges from .22 rimfire through .50 BMG, plus 20-gauge and 12-gauge shotgun applications. The universal design requires no optional arbors or caliber-specific adapters—a significant advantage in high-volume armory environments where quick reconfiguration between platforms is essential. The green laser wavelength (typically 532 nm) remains visible in daylight conditions where red systems falter, ensuring consistent performance during both indoor and outdoor zeroing sessions.

Tactical professionals benefit most from this tool when establishing zero references for new optics or validating zero integrity on duty weapons before deployment. The boresighter's compatibility across all rifle calibers, pistol platforms, and shotgun gauges makes it an essential component of any armory's maintenance protocol or gunsmith kit. At 1.2 pounds with compact dimensions (5.9 × 2.15 × 9.75 inches), it travels easily between range bays or fits in standard tactical gear bags for mobile zeroing operations.
