Finishes

Black Nitride – The nitriding process involves a salt (chemical) bath which provides corrosion resistance and hardens the surface of the steel (~740 HV). This thermo chemical treatment gives you a far more durable and smoother finish than the original Mil-Spec magnesium phosphate.
Nickel Boron – The UCT EXO® NiB has a higher boron content than any other commercially available nickel boron which provides this BCG with an extremely hard (~1800 HV), durable finish. It is very smooth with a low friction coefficient.
Diamond Like Carbon – This DLC hybrid is a next level coating that is even harder (~2300 HV) than nitride or nickel boron. It is smooth, easy to clean and has a deep, dark gray color.
P51+ High Polish Black – This has all the same attributes of our DLC hybrid, but it receives extra polishing cycles to give it an EXTREMELY smooth and deep, black finish. It is even harder (~2300 HV) than nitride or nickel boron.

    These guys are great im a iraq combat fallujah veteran I spoke to them I feel lucky I snagged one of these while they had it and they aren’t price gouging people amazing veteran owned company im building a 18 inch grendel upper this was just what I needed just waiting on the scope (= beautiful uppers made in the USA you know you are getting quality with these folks I also bought a extra grendel bolt which I recommend everyone does in case you’re other one fails or it’s a cheap way to convert a regular bcg onto a grendel bcg thsnks guys!
