The SME BULLET LASER BORE SIGHTING SYSTEM 20 GAUGE is a precision tool designed for rapid, accurate bore alignment when mounting scopes on 20 gauge firearms, delivering an intuitive, single-instrument solution for range-ready setup. This bore sighting system uses a precision laser to simulate a cartridge exit, enabling shooters to visualize bore alignment with the bore and scope axis without live fire, which accelerates precision engagement and zeroing work at the bench. Compatible with ACC_20 Gauge cartridges, it integrates seamlessly with standard scope mounting platforms to provide repeatable reference points for windage and elevation adjustments, helping range-day workflows stay efficient and focused. Built for durability and reliability, the system supports safe handling and straightforward installation, allowing hunters and competitive shooters to verify alignment across different mounts and optics configurations. By providing an immediate, optical reference from the guns muzzle to the optic, it reduces the guesswork of initial sight-in sessions and supports consistent hit placement at practical ranges. Whether refining a new optic setup, performing routine maintenance checks, or preparing for a hunting trip, this laser bore sighting solution from SME enhances confidence and accuracy for 20 gauge applications.
