I need the Armalite pattern barrel nut for the Daniel Defense AR-10 762 Lite Rail pattern rail system. I have a couple of the DPMS pattern barrel nuts but I need the one specifically for the Armalite AR-10 brand rifle.

I bought two of them online and both ended up being DPMS pattern even though they were listed as Armalite. Apprently the shops that still have these don't understand there is a difference!

If anyone has one, shoot me a PM please.
