I'm looking at options for a 14.5'' or 16'' 5.56 build, and it'll probably be either a DD or Noveske barrel. The DD receivers are very scarce actually, but the Noveske receivers are available. My only thing on the choice of barrels is that Noveske is about twice the price as DD. I know both are solid platforms, but I'm not sure why exactly their barrel prices diverge so much. Anything to consider on this decision?
