Great fit and function, BLACK not Nickel Boron
Picture is of a nickel boron bcg. Saw the back in stock notification, and snagged it like the last front row seat at an AC/DC Concert without reading full description. When it arrived I initially thought my item may have been misboxed as it was black, but reading fully this time I found it clearly says black. And I mean black as black. My mistake, not theirs, (just like the ADHD benifit concert I was front and center to.)
Fit and function are great, firing pin hits milspec steel cases normally, and overall very satisfied with the mechanics and useability of the part.
In case you only scrolled and looked at the picture without reading, it's for 7.62x39, and it comes black despite picture.
