I'm about to put together my first AR upper and from all the info I'm researching in preparation to do the build, all of my sources specify AeroShell grease on the barrel nut threads in prep for the torquing procedure.
Why specifically AeroShell as opposed to other greases?
There's assloads of other greases that are of the same basic composition, lithium with moly disulphide. Skip the graphite and all should be fine. Standing by for the horror stories of anyone that used something else, yet similar, and it went bad.
