Actually the BCG is blued (black oxide) and not nitrided.
Nitrided BCGs are not chrome plated inside where the bolt goes. The entire BCG inside and out is a rather flat black with a little sheen to it.
The nitrided BCGs that I have are somewhat easier to clean than phosphate or bluing treated BCGs.
