See the link in Danofree's post above: that's Umbrella Corp's page for their small package of AeroShell 33MS.

It is the "correct" product because:
> It meets the specific criteria called for in the Army TM for the M16 family of rifles
> It is widely available and inexpensive
> It stores for a long time
> It only takes a dab for each barrel, and
> It meets the specific criteria called for in the Army TM for the M16 family of rifles (yes, I repeated that - it's important.)

A grease that meets the MIL-G21164D standard is what the upper/barrel nut interface was designed to use.  Its viscosity, stickiness, and ability to spread all contribute to getting an accurate torque on the barrel nut, while something cheap from the auto parts store may work "OK," but won't be the same consistency and slipperiness, so your barrel nut torque may or may not be right.  If you spend $5 and get 1/2 oz of AeroShell 33MS from Umbrella Corp, you've got enough for a bunch of builds, and you know it won't hurt your parts.  That's not something you can say about that Wal-Mart special, made who-knows-where, generic grease.

Goop the stuff on the threads and goop the barrel extension before stuffing it in the upper too. Wipe off the excess afterward.
