I got this for a build where I was wanting to match up the blacks. The ATC castle nut is very black, but was TOO shiny/glossy. So if you want a castle nut that is turely black AND shiny this would be for you.

This was a very close match to my Magpul FDE furniture. Very pleased with the quality of the coating. Went on and has stayed on with zero issues

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.
