Some time ago, I heard about nickel based superalloys with cobalt based linings being used to make machine gun barrels and tested for some military applications. Today I happened to stumble across this:

I'm sure it would be overkill for a semi auto AR, but I wonder how likely it would be that these would end up on commercially available rifles down the road. While we're on the subject of superalloys, I also came across a patent from 2012 for John Noveske. It was for an extreme duty machine gun barrel made of H13 tool steel. Pretty tough stuff. This is the same alloy Wilson Combat manufactures their TTU triggers from.
