Replacement O-Ring Set for SiteLite Laser Boresighters SL-ORINGS

If you have misplaced the factory set of o-rings that came with your SiteLite, this is an exact replacement.  This is the set of o-rings that are included with every new SiteLite laser boresighter, packaged in a clear plastic clamshell container.    

When using SiteLite boresighters, o-rings should always be lubricated using silicone grease or Vaseline.  Never use gun oil to lubricate o-rings, the oil will break down the ring and cause premature failure.
