What grease/oil do you use for AR barrel installation/builds

I've heard some say nothing special is needed, others say to use a specific type of grease.

This for anything that slides:



and Lucas Gun oil for anything that rotates (just because I have had a bottle forever).

This is the assembly lube all the heavy Diesel engine manufacturers say to use during an overhaul. We affectionately call it whale cum. Paired with BG pre lube I.E. duck butter has built many million mile engines it is good stuff

Apply to threads of nut. Tighten to 50 pounds and release 3 times, then final torque. If you have a 7075 receiver and a match grade barrel, getting between 85 and 100 pounds will give you the best assembly.

Just be careful of galvanic response. Some greases will eat the aluminum if moisture is present.
