barrel torque for ar-15

when installing a barrel on an ar-15 upper, what is the torque necessary for proper fitment, if any, and how would you measure this if necessary?

You would use a inch pound torque wrench, but I usually tighten until snug with a barrel nut wrench, then center the nut slot/hole for the gas tube since it will holt the nut in place anyhow.

thats what i did with my last build, just wondering, had some guy telling me "i hope you had the right torque on your barrel, you'd hate something bad to happen"
Nah it locks up in this fashion. Also the headspace is set already so you have no issues there.
