As of 2021 is DLC the top of the line coating?

Specifically for AR bcg and barrel, is DLC the top of the line coating?

How about other firearms such as pistols, bolt action rifles, shotguns etc?

Depends on what you mean by "top of the line coating"... for AR BCGs I still prefer the traditional phosphate coating as it helps hold and keep oil in place. All the fancy new coatings are super slick and oil tends to migrate where it wants to when in storage.

For other guns, Yeah, DLC is probably the most durable but all coatings will wear eventually.

I prefer nitride as it's a treatment, not a coating.

Problem with nitride, while very hard and durable, it only effects the metal few microns in... better than bluing though.
