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. Tom (verified owner)

    Love my 6.5 Grendel BCG I got from Grendel Hunter. I think the extra money for the DLC coating was well worth it. Already took it to the range and it ran perfectly.

  2. Anthony Brown (verified owner)

    Very quick shipping, product appears to be quality made. Head spaced is perfect. I would definitely recommend this product.

  3. Mark (verified owner)

  4. Benjamin Decker (verified owner)

    I have not been able to shoot my build yet but as of now I am very pleased with this BCG quality smooth and silky quiet action.

  5. Scott (verified owner)

    I purchased this for a build in almost done with so this review is based on unboxing and first impressions. Overall construction is 5 stars. No marks of any kind on the bolt or carrierand the coating is smooth and consistent. Although I haven’t fired it yet I’m confident it will perform as expected.
