I pull the upper, remove BCG, clamp in vice (handguard with rubber jaw inserts), boresight like you would a Bolt gun.I don't own an AR, but just out of curosity, how does one bore sight one of those without a light or laser?

Best to bore sight at closer range , then it should be on paper at 50 yards so you can sight in. Never heard of bore sighting at 100 yards.
The issue seems to be barrels that are mass produced and hastily threaded cockeyed or off center. Believe it or not almost every factory barrel has a curve or bend to it, in fact mass produced barrels are more often than not less-than perfectly straight.
