ATRS also told me they can order a 20" DPMS.
Your best bet is to probably get export permits and order one from brownells.
Daniel defense is so swamped they are only doing complete rifles at the moment, so if it isn't in stock you won't be getting one from them for a while.
I just got word my 20" is done at ATRS, I just have to cut them a cheque. I know Epps says they can order anything DPMS.
