These are not grey like the picture shows but a lighter black/brown color. I bought these when they were $199 so obviously this is a good deal. It's pretty similar to Nickel Boron just not chrome in appearance.
I did a lot of research on these and guys at ARFCOM (AR-15.com) all had good things to say about these BCG's. There are no names or nothing said about who manufactures them except that the parts from ARFCOM seem to be of decent-high quality.
How does this compare to Nickel Boron? I was holding out for those to come down to normal prices, but this is intriguing.
