BSA BS30 Bore Sight Kit Pistol/Rifle Multi-Caliber .177-.50 15 Arbors Hard Case

The BSA BS30 Bore Sight Kit is a multi-caliber collimator-style boresighter designed to get you on paper quickly without firing a single round. Purpose-built for both pistol and rifle barrels, this alignment tool saves time and ammunition when sighting in optics or dialing in iron sights.

The kit ships with 15 arbors covering popular calibers from .177 through .50 caliber, fitting the vast majority of common pistol and rifle bores. Insert the properly sized arbor into the chamber, look through the collimator, and adjust the optic's reticle until it aligns with the crosshairs projected down the bore. This "get on paper" step dramatically reduces the live fire required to reach a final zero.

A durable metal body and a heavy-duty hard case keep every arbor organized and protected during transport and storage. The collimator design projects a clean reticle pattern that makes bore alignment fast and intuitive at the bench, on the range, or in the field.

From zeroing a red dot on a new pistol to dialing in a rifle scope, the BSA BS30 multi-caliber boresighter kit delivers the versatility and caliber coverage to handle the job. Compatible across pistol and rifle platforms, it is a practical alignment tool every shooter should have on hand.
