I just hit google and found those to claim to have what you desire.

I’d wait just a bit for Daniel Defense’s DDV 6.8. It seems to be exactly what you’re looking for:

ar15performance and titan armory offered great chrome middies, but now I think they are doing one better with nitro-carb. visit 68forums.com and check it out. +1 on no milspec (yet) for 6.8 AFAIK.
