Osprey Global 20GA-BS Laser Boresight: Quick, repeatable sighting for your 20 gauge

The Osprey Global 20GA-BS Laser Boresight is a compact tool built for shotgun enthusiasts who want a reliable method to align a scope on 20 gauge rifles and shotguns. Encased in a solid brass body, this device houses a red Class IIIA laser with a power under 5 mW and a wavelength range of 635–655 nm. Weighing just 112 g, it offers a balance of durability and portability that suits range trips and field use without adding bulk.

Designed with practical shooting in mind, the boresight projects a precise aiming dot that helps you verify alignment at typical field distances. The result is a workflow that can feel faster and more repeatable when configuring a scope and checking zero before live fire. While results may vary by shooter and setup, the boresight is positioned as a helpful tool for confirming whether scope adjustments are needed.
