I just use Kroil, Gisele ALG Go Juice and their 0000 very fine oil. I do also use a synthetic grease applied to the lugs of every rifle.
I can tell you with certainty that there is nothing that works better than Kroil in an environment with very fine carbon dust in the air. I use a spray can for air tool oil and it is the only one that has kept these 18000 - 24000rpm tools running with no hiccups. I have tried every single CLP, Gun lubricant, air tool lubricant, synthetic oil, traditional oil and wonder slick em snake oil. Every single one of them either significantly reduced rpms or gum up to the point I have to stop and flush them out and go back to Kroil.
Fine carbon fiber is probably far worse than any environment that a firearm would see. I apply it and blow off the excess.
YMMV
