Kandahar firearm lube ?

Yes graphite is conductor...but aluminum oxide does not develop as pitting. Either way, the important thing for the operator is to keep the gun moving.....not to worry about finish wear and service life.

A clarification...

Trevj pretty much has it right. We're not talking about aluminum oxide here, which I agree does not typically form pits. The corrosion occurs through galvanic action - basically the graphite and the aluminum form a battery, with salty water (sweat) as an electrolyte. The aluminum compounds that result most certainly do cause pitting as they are created.

As I said in my original post, this is a long-term process. I'm not saying that graphite is or isn't an appropriate lubricant - I'm just saying that if used long-term, it may lead to corrosion of exposed aluminum (i.e. coating/anodizing worn off).

Fair enough if you want to talk what may happen in theory about galvanic corrosion...but don't worry about it. It won't happen to you.

If you want to use an example of a structure formed with steel and some other metal without coatings, touching in each other and standing off the coast of NL, fine we can talk galvanic corrosion...

Militec-1, when used as a regular lube, is about as good as many others. The secret to it is to literally bake the gun parts in the oven after application.

That's something I suspect our soldiers aren't going to be able to do...

There's a lube marketed in the bicycle industry called Tri-Flow. It's good stuff, really heavy on the suspended teflon in the liquid. I suspect it would work great when applied liberally in a dusty environment; it keeps bike chains and gears moving nicely when covered in mud and silt.
