Wheel Bearing Grease (Hi temp) On AK

[studmuffin]

I have never heard of tight tolerances on an AK

Only by accident.

[O.S.O.K.]

Is there any difference between the silver, gold and copper colors of never-seize, or is it just marketing?

Roger, without looking, I don't know. I do know that the standard silver anti-seize works great and takes only a very little amount. I mostly use this on my semi-auto slides but I've used it on my AK's and it worked fine. Can't really see any difference between that and regular CLP but then again, I'm not running them that hard...

ive used wheel bearing grease before on ak's. just a small smear on teh hammer face and on the bottom of the carrier where it rubs the hammer face and a little bit in the recesses where the rails run.

when im not in the grage, most everything gets oiled. ive got clp and gunzilla that i use on "friction areas" (ill put a drop on hammer and trigger pins and teh like) most of the gun will get a wipe down with rem oil, hoppes gun oil, or clp, and for the "high friction areas" (like slide rails on pistols and the aforementioned hammer contact area on an ak) i also like the tetra grease. for the small amount i use, the small (under $5) tube will last me years.

ive never heard of gold antiseize, but afaik, the the silver is rated to a higher temp than the copper, and and is chemically inert, so if using the copper is causing galvanization issues you should switch to the nickel. other than that, same same.

i however have lost most of my faith in it. a while ago i switched to it at work for lubing the sliding pins on brake calipers. i used to clean the old lube and relube them with high temp grease every time. then i look at anti seize. super high temp, never hardens, should be perfect, right? one and done. no way. every car i tried it on it hardened up in short time and froze the calipers in place, and is a mother fucker to get apart and clean off after. ive got very little use for it any more. pretty much only time i use it now is when i NEED electrical conductivity through a fastener.

I've read somewhere that anything containing graphite is a big no-no on aircraft (maybe guys that work in that industry can chime in) because of the difference in galvanic potential of graphite and aluminum. Also, I'd swear I ran into a journal talking about SCC (stress corrosion cracking) due to anti-seize being used on steel as a thread lubricant when I was dealing with a fatigue problem a few years back (our problem was caused by something else entirely).

on AR's I have been hesitant to use graphite based lubes for this reason but because of the passive anodized layer they are probably fairly protected and you also need the presence of an electrolyte to have corrosion issues. I wouldn't be too worried about SCC either as I believe it generally only occurs in very corrosive environments but I havent used anti-seize as a gun lube before.

Now if you were scuba diving with your AR and had scratches through your anodizing you have have used graphite based lube you might run into trouble in the long term.
