From what I've read, moly grease should be used on the barrel nut during assembly of the rifle. The stuff I read on AR15.com said you can find the stuff at auto parts stores. Last night, I bought some Valvoline (moly fortified multi-purpose grease) (http://www.valvoline.com/pages/products/product_detail.asp?product=68). When I got home, I noticed that it's only good up to 400F. I doubt the Valvoline grease has more than 5% moly. I looked around the store for about 30 minutes, but I didn't find anything better than the Valvoline.

After doing some surfing, I found out that local honda motorcycle dealers sell 60% moly grease. It claims to work on moving parts up to 750F and stationary parts up to 1500F.

The moly grease on the barrel nut only serves one purpose--it prevents the galling of the receiver thread by the barrel nut when you apply torque. Beyond that it serves no other purpose and its irrelevant if it stays on or smokes/melts off... There is absolutely no reason to go gaga over what brand/quality/spec you are using here...it will have no bearing on how your rifle performs. I've used Valvoline grease for 6 rifles with no problems at all...

I've used Brownell's Action Lube Plus on the 2 that I've done. It seems to work fine and has the moly greese in it and with the jar I have it's a lifetime supply and then some.
