I am trying to put a new barrel onto my upper, how do I know if I have it tight enough?

When your gas tube is perfectly lined up and your torque wrench registers more than 35 ft-lbs. Or put a ratchet on it with a 1 foot handle and hang 35 lbs off the tip. You get the idea. Practice on a lug nut if you don't know generally what 35 ft lbs feels like. Max out at 80 ft lbs, though that's really high torque.
