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?

everywhere ive seen it states 30-40lbs it gives u a range so that you can align the holes for the gas tube. when purchasing an ar barrel...should i order the barrel and bolt from the same manufacturer or will they all headspace correctly?
