Lightbulb Oil vs Grease in Gas Piston Upper.

Converted some AR rifles to gas piston which are safe queens. On a DI system I would most definitely not use grease on the BCG as it will collect all the fouling from the gases.

Now that fouling in the action is non existent would it be more beneficial to use grease vs oil? I just don't like the fact that oil evaporates over a period of time and that I'd have to relube every couple of weeks.

I have used grease on my GP external and DI internal gas piston AR type rifles/pistols for years with no issues.
Grease contact points on carrier, bolt lugs/body, (+gas rings DI only).
It lasts and dosen't drip or burn off.

What kind of grease did you use? I was thinking of using some lucas white lithium grease that I have on hand.

If you deal with a lot of grit oil if not grease on everything that slides and ATF on everything that rotates on bench rigs. I mainly use ATF on everything else except on contact points of the FCG on SHTF rigs.

On the BCG or on the piston itself? You can use grease on the rails and oil everywhere else. . . however it's pretty pointless to oil the piston itself, it'll just burn off. That's what I do with my HK at least.

As for grease, get this, it'll last you forever:

Was just going to grease the bolt and carrier. My Adams arms piston needs no lube.

I use oil for all components of my rifles and pistols. I find that "grease" changes the impulse nature of slide components and is more difficult to remove in a cleaning.

OP.
I use high temp wheel bearing grease. Nothing special is needed. YMMV
Caveat, little bit goes a long way. I have seen shooters/users put too much on and even the grease makes a mess. Still shoots/functions well.
The poster that said ATF for lube is right. It does work well and is cheap too.
