The chrome process is a chromium-alloy overlay onto the inner surface of the barrel. Nitriding is a salt-bath/heat treat of diffusing the nitride into the entire barrel surface (except for extension in most cases), it's a merge into the surface a very tiny but super hard additive, it goes IIRC about 50 microns deep into the barrel steel. No dimensional change to the steel.
Any chemists or metallurgists on here could correct me if I have it wrong.
But you wouldn't or shouldn't be looking for both.
Edit to add: I've read (but can't put my finger on it) that you really don't want to nitride SS, best thing is a quality, hand-lapped smooth Chrom moly barrel. The nitriding works better on that metallic-wise, if I recall the article.
Oh good lord no lol! I meant nitride or chrome, since Criterion offers both in their hybrid line-just not for Grendel that I can find.
And to availability, I’m not certain that our civilization, let alone our country will be around that much longer to be honest.
