You need to either pickup the OmegaX/MFR DD wrench tool or a castle nut wrench from an armorer's wrench (open mouth with just a single hook) which I've used to remove the OmegaX barren nut on my V5.
I needed the same DD wrench for one of my rifles. Only problem is that I was having a tough time sourcing one out in Canada...what else is new? I called Daniel Defense and asked them for one...sure enough, they mailed one out to me free of charge. Good folks, they are...
