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.

  1. R.T. (Bobby) Blanchard (verified owner)

    Excellent delivery time, product as advertised!
    Great upgrade to my build , definitely has resolved my issues in running a suppressed gun .
    Will recommend to others!

  2. sebastianbenham (verified owner)

    Nice and shiny! Also does the job, and was quite easy to clean. I haven’t put it through the ringer all that much yet, so we are yet to see long term durability, but I believe this BCG will hold up to its duty. Certainly gives compliment for a bad ass looking rifle!

  3. Mike O’Connor (verified owner)

    My 6.5 Grendel BCG in Nickel/Boron has a beautiful polished, slick finish that cleans up amazingly well. The finish shows no signs of staining like some of my other BCG’s in N/B. Best of all the BCG performs flawlessly!

  4. Chuck S. (verified owner)

    A piece of art, worked perfectly, easy to clean. What more can you ask for? Buy one, used for a 22ARC and 6mmARC, right bolt face dimensions.

  5. Brett Coney, Coney Tactical Innovations (verified owner)

    Great quality at a reasonable price point. I am excited to work with Grendel Hunter for future purchases.
