Put grease on the bolt lugs and the cam pin on the bcg?
those seem to be high pressure/friction areas so i thought id put some grease there to help slick things up a little. does anybody else do this? good idea? i dont put a lot on there.
I tried using grease on the bolt lugs and cam pin. I found that the grease would get thicker as the weapon fouled from firing. Its my opinion, for the weight of the M16/AR15 parts and the close tolerances between the parts, its better to use a good gun lube. IMHO Grease will only make the rifle get sluggish and could lead to reliability issues.
Do not use grease.
no grease…always use oil.
James Yeager of Tactical response thinks it is a good idea.

No grease here. Just oil.
Another good reason to avoid grease.
Thought I read somewhere to “grease bad guys, not guns.” 
Completely unnecessary. Any descent weapon oil will do, even vehicle motor oil. Stay away from the light weight oils (WD40, Remoil). They will work in a pinch if it’s all you got, for emergency lube, but won’t last as long.
Grease on the bolt lugs seems like a bad idea for the above mentioned issues. But I’ve used it on the cam pin and carrier bearing rails with great sucess for years.
The cam pin assembly on any other machine would obviously be a grease point and not an oil point. And the rails on the carrier are ideal because you keep a light lube where you want it instead of gettling oil all over the inside of the receiver… and thus having a greater surface area for grit to stick to.
ill probably knock it off then with the grease.
just out of curiosity, would gear oil make a good AR lubricant? its smells like shit but its a thicker oil that i would think would resist heat well?

It would probably do ok, but I could never get past the smell. I HATE draining my transmission to the point where I’ll pay to have it done just to not have any part of me smell like gear oil.
I agree.
TW-25B works pretty good. I have used it on my Noveske without issue. In the Coast Guard we used on the M242 25MM cannon.
Paul Howe uses a shitload of grease on just about everything in his upper…but not on the locking lugs. I don’t remember his gun malfunctioning or growing warts as a function of it either. I don’t currently use grease because oil works just fine, but I plan to try grease on the cam pin and carrier rails in the future.
ETA: Should we avoid trigger control sight alignment and the four basic rules of firearms safety because Yeager says those are important too? Perhaps we should avoid Glocks? Please.:rolleyes:
im switchin off to Mobil 1 15w50
I use mobil 1 synthetic I am happy with it.
I dont use grease at all on ANY firearm!
It just gunks up
Breakfree LP generously on the bolt carrier group (gas rings, cam pin, lugs)
Breakfree CLP lightly on the firing pin
Breakfree CLP everywhere else.
