Looks like it is upgrade parts and not really a "lubricant" Looks like they are only doing the ar and 1911 platforms.
Personally I have had good luck with grease on the m14. It may collect dust and grit but I haven't had a stopage because of dirt. These pictures were taken out in the grasslands on a REALLY windy day. I had to take brake cleaner to get the grit off, but I didn't have one malfunction
