			In cold temps, I run my AR-15 with dry graphite or dry teflon lube. 
In the long run, I think that the teflon is prob the better choice. 
All in all, it is toss of the coin. I have used both and they have never let me down. Both come in what I call "poof" bottles. 
Disassemble all parts, clean them "bone dry" and give all parts 
a "poof" of dry lube.
