If you have a full auto, it will definetely turn black. If not, then you really have to heat one up before it will turn it black. I bump fired 3 mags through my AR once and the only thing I noticed was the first inch or two of the gas tube turned dark.

If you are really worried about it, you can use duraheat. It will take temps up to 1800F.

Any suggestions for a barrel finish that won't trap in heat? I've used Dura Heat, and it seems to do that.
