Considering this is the same wording used by others known to use FN for the chf barrels (Centurion, Spike's, Noveske), is it safe to say that these are also by way of FN?

It wouldn't surprise me. To have FN make barrels for you its a 300 unit minimum order, I'm sure an outfit like Rainier would do that pretty easy.
