Description Meloniting, also known as black nitride or nitro carburization, offers increased abrasion and corrosion resistance. This treatment lowers the coefficient of friction and increases the life of the bolt carrier group. Unlike plating, this process penetrates the surface and wont flake off, maintaining all the original dimensions. Our bolt carrier groups are processed with the QPQ process.
