Why does everyone tell me not to use...

[Andrew Wyatt]

I think you guys are overestimating the amount of grease necessary.

Up to 500 between cleanings, and no stoppages due to the action gumming up. But I use it sparingly, just a few small dabs rubbed at key points in the action. Must lubing comes from CLP. I've never noticed any accumulation of grit at those points.

Same here. I little grease on the cam pin and carrier contact points, then some on the buffer, CLP elsewhere. Works well, but I don't think that not doing it this way is wrong.

I learned a long time ago as a kid that anything I use outside normally does better with oil over grease. Grease seems to attract sand and other junk like a high powered magnet.

Why does everyone keep telling me not to use high temp synthetic wheel bearing grease in my AR's?

Maybe the same reason they tell you not to use gun oil in the engine of your car? Could it be that they are trying to get you to use a petroleum product that's designed to perform within specific temperature and load parameters, and the sliding loads (high shear) and combustion gas temps that are experienced in your AR15 are not the same as the rolling loads (low shear) and relatively low temps that the wheel bearing grease is designed for?

AR's dont like grease.

My ARs do...

I use an 1/4" artist's brush to paint on Lubriplate 105 on the locking lugs, slide rails, cam surface for summer shooting. Lubriplate 105 is a thin grease, I would not use heavier.

I still rub all metal parts down with an oily patch before I apply grease.

For winter shooting I use LSA or motor oil. You can gum up a AR in cold weather.

Incidentally, that is true of Garands/M1a's. Grease is only to be used in temperatures above the 40's and it says so in the Rifle grease Spec. Below 50's degrees you are use oil (LSA is still great stuff). In artic conditions you took all greases and oils off.

I like a thinner grease. I actually created my own by mixing synth bearing grease with synth atf until it had a consistancy that I liked and have found it very useful. Sort of a molasses thickness.

FWIW this 3-gun was shot in temps from -3 to 20 degrees fahrenheit. Colt SP1 lubed with standard moly wheel bearing grease.
