I received an email from the Owner of Black Widow Armament, Eric Isaac, today. He informed me that the manganese finish NoMar plate is not the standard, the Black Oxide version is. The manganese finish models were for samples only and were not intended to be sold in that finish. I was also sent an image of what the Black Oxide model looks like, which is attached below. I believe that there is also a possibility of an additional finish being released, but I do not want to speak out of turn.
