Update- spoke to the seller. They are taking the action back. H&M did do the nitride and said that it is rare but it does happen that the chemicals for whatever reason do not mix or heat right and the action will turn brown or even splotchy looking. At this point I can return it, or they will bead blast it down again and refinish it/nitride it again. I've asked the obvious, what happens to the embrittlement of the material, how much surface material is lost or what can change as far as tolerances etc. At this point im 90% certain I'll return the action. I don't know what 1,000* deg again, or blasting the finish off a second time will do but I do know it's not something they PLAN on doing ever. So would it be ok… maybe. Am I willing to take a chance on a now $1,600 action that I feel should have been right in the first place….. Nope. But I'll sleep on it. Hope this helps someone down the line.
