BSA Boresighter with 15 Arbors and Hard Case

The BSA Boresighter with 15 Arbors and Hard Case is an essential tool for shooters looking to achieve precise zero without firing rounds downrange. This professional-grade alignment tool is particularly useful for those who frequently switch between different calibers, as it allows for efficient bore alignment.

The boresighter functions by inserting caliber-specific arbors into the bore, which optically aligns your scope or sight with the barrel's centerline. The system includes 15 arbor options, covering a wide range of calibers from .177 to .50. Each arbor is precision-engineered to match the bore diameter, ensuring accurate alignment.

This comprehensive system is ideal for shooters with multi-caliber arsenals, as it simplifies the zeroing process and reduces setup time. The durable hard case keeps all arbors organized and accessible, making it a practical choice for both range use and transport.
