What finish is on my 870?

[41 Colt]

I have a Remington 870 with some type of custom finish. The previous owner did the work but I can't remember what it was called...graphtech comes to mind but I could be way off. Looks cool IMO.

Here's a close up.

parkerized? Nitrate (tho I only believe remington does that)

Not sure on the finish but that is one fine looking shotgun.

Better send it to me for a better look. I'm with Egg on this one, I have no idea, but love the look of the gun.
