It's a good idea to put some grease on the threads of your upper receiver before you torque on your barrel nut. Molybdenum disulfide grease is recommended by the military, but some well-placed sources (ADCO Firearms) say that any type of synthetic wheel bearing grease will do.
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 shouldn't have a problem with headspacing. Everything is supposed to be Mil-spec and therefore should work fine. One of my buddies has a set of headspace gauges, but I have never checked the headspace of my AR builds. YMMV.SHANE704 said: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?
