Magic lube

There's a magic lube II that is silicone based. That's the only one I would use. The basic one says Teflon based, which is crap because as far as I know, there's no such thing as Teflon oil. I'm guessing it's mineral oil based, similar to Vaseline with Teflon added. Silicone is cheap, guns aren't, so I would stick with a silicone based lube personally. That is what every manufacturer says to use.
