TRIBOLOGICAL COMPARISON OF TRADITIONAL AND ADVANCED FIREARM COATINGS
This essay seems to be based on ar-15 or M-16 rifles .This article may appeal to gun Geeks here,I am no expert.

The objective of this project is to find which type of coating has the best performance characteristics for finishing firearms. This is accomplished by measuring and comparing several performance characteristics, such as: adhesion, hardness, wear resistance, friction control, and corrosion resistance. Appearance is not a factor since any exterior coating that is flashy can be subdued or camouflaged with special purpose paints, which have proven durable enough for such purposes. Cost will not be a limiting factor for this experiment, but will be discussed in the conclusion as a secondary concern. This data will be used to identify the best coating for steel and aluminum firearm parts. The goal is to lengthen a firearm’s life cycle while increasing performance and reliability by applying the best coating.

140 pages! If it rusts I will oil it.

I don't have the time or patience to read through 40 pages.
My unscientific testing indicates that what is commonly referred to as "nitride coating" is far superior to other surface treatments I've used and apparently is one of the cheaper alternatives.

I think the military has better technology for rapid firing barrels.I can't be sure but some kind of ceramic nanotechnology is possible and Yep here is the link below.

Unlike topically applied friction reducing liquids, the nano-ceramic (subatomic) particles actually fuse to the metal barrel surface, filling in imperfections and surface irregularities. It will effectively redeposit a cermet coating on worn barrel surfaces, adding measurable microns of ceramic/metallic fusion material to the bore. This will increase back pressure while providing newly incredible consistency in Shot-to-Shot velocity.

nitride is very good, is not a coating but a treatment that surface hardens and rustproofs the metal, but then you can't chrome line inside the barrel. gotta have my chrome lining.
