Not shiny black - AT3 Tactical Castle Nut for AR-15 Buffer Tubes

I read the review, and expected a shiny, black castle nut. I received 3 dull, flat black castle nuts. These were on back order for over 3 months, and when they arrived, not even meet the description. They are steel, and work fine, but the color for my guns will not work. Now I have to order from someone else.
