Are some barrels going to be more sensitive to a nitride treatment than others? The treatment processes are pretty high temperature, and while intuitively I'm giddy at the possibilities of a very accurate, very long-lived stainless barrel, I'm not wondering if the barrel will actually hold up to the treatment with no ill effects.

I just wanted to follow up on this. I've done a few of these barrels in the last few months. The barrels and extensions are treated installed as is the gas port. Actually the barrel needs to be broken in, I should say burnished, prior to treatment. This is great because I've been able to get some accuracy comparisons before and after, but I'm still finalizing those. The color is a very deep black and is pretty matte. I'll take some pics and post them up. But over all I am really happy with these so far in my SPRs.
I think there is a large misunderstanding of the temps involved in this process as it is applied to barrels. The temps do not cross 900 Deg. so "Warpage" and "Distortion" are not present. These temps actually serve to stress relive the barrel after all of the machining has been done, which is the exact opposite of about every other barrel.
I can't obviously attest to durability when compared against Chrome, but just based on the available data this is the perfect route for accuracy intended guns.
