About Nitride – Nitride is a class of chemical compound in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. A black coating that makes the gun’s metal 10 times stronger than it was originally.
Nitride coating sickens the surface to make the carrier extremely lubricated. By nature of the process, the steel is hardened through a thermochemical treatment to the steel which makes the steel harder and resistant to water penetrations.
