LocTite 243 is "blue" (medium strength), oil resistant, somewhat expensive, and hard to find (Try an auto parts store or Amazon). If you ever want to remove the barrel from the upper, use a 1" dowel rod and hammer it out from the breach end (obviously). I've bedded three barrels with one of the "small" tube, and there should be enough for at least one more.
