I'm not convinced it's non corrosive.i've got a case with the '95 cj headstamp in the plain white boxes of 20.
I shot some 2 weeks ago and my yankee hills flash suppressor had surface rust on the insides.the gun was cleaned and well oiled the same day shooting it.Also there is a lot of green residue around the chamber.Someone,maybe me,needs to do a nail test on this chinese .223.
