Melonite is a form of Nitrocarburizing. It will not be as thick as a chrome lining is since it is on the molecular level instead of a lining.

From what I read you better finish machining or drilling on a part before the treatment because the process hardens a part significantly.

I have owned a AR15 without the chrome lining and never had any problems.
