The BSA Optics BS30 Multi Caliber Boresighter Kit is a complete boresighting system for pistol and rifle calibers, supplied in a heavy-duty hard case. It includes 15 rifle and pistol arbors that match barrels from .177 to .50 caliber, plus 3 shotgun arbors for 12, 20, and 28 gauge, so a single kit covers a wide range of firearms. The replaceable arbor system lets the kit be maintained and reused over time rather than replaced.

Boresighting with this kit helps get shots on paper before live fire, saving ammunition and range time when zeroing optics. The hard case keeps the arbors and components organized for transport to the range or field.
