So apparently my barrel at CMMG was cancelled. So I guess I'll see who else can make it.
BCA has complete uppers in stock, but they are 16" chrome vanadium barrels. Craddock precision and Deadshot barrels will make barrels.
I found it interesting that Craddock claims standard 5.56 magazines will not feed correctly, which is a surprise given the cartridge is just a blown out 5.56.
