Great product - Bushnell Laser Boresighter w/ Arbors

It may not be as fancy or as technical has some other bore sights it does the job with simplicity. Like all items iof this nature you need to make sure it working correctly. I used a drill and spun the dvice to make sure the lazer wasnt making a circulat pattern. Didn't have to make any adjustments to mine but all the tools are there to do so.
