Black Nitride is becoming more common and slowly replacing the parkerizing of steel parts. Most chrome moly barrels that were parkerized in days past are now melonited, which is a fancy name for black nitride. Nitriding vastly increases the hardness of the metal that is treated without changing the material dimensionally like the build up of a hard coat. This treatment is great for use on barrels to prevent corrosion and increase barrel life. A barrel that is nitrided is going to be more accurate that a chrome lined barrel because chrome plating takes away some of the sharpness of the rifling. The black nitride treatment is very durable and highly resistant to wear and it will not flake because it is not a coating.
