Get on paper without wasting ammunition. This 15-arbor boresighter covers calibers from .177 to .50, helping you align your scope and barrel bore quickly. Includes heavy-duty hard case.
The BSA BS30 is a practical tool for any shooter who wants to save time and ammunition at the range. Rather than firing shots to find your zero, this boresighter allows you to optically align your scope's crosshairs with your barrel's bore before you ever pull the trigger.
This comprehensive kit comes with 15 arbors covering popular calibers:
Each arbor is precision-engineered to fit your specific caliber, ensuring accurate alignment every time.
Get on paper immediately. By aligning your scope to your barrel before shooting, you eliminate wild shots and wasted ammunition—especially valuable when ammunition is scarce or expensive.
Verify zero after travel. If you've transported your rifle or it's been in storage, the BS30 lets you confirm your setup is still true without firing a shot.
Save time at the range. Spend more time actually shooting and less time chasing your zero.
All arbors and components are protected in a heavy-duty hard case, keeping everything organized and protected for years of use.
