Rugerslinger,
Hey, this is Fourrunner off of the site linked above and the one selling these wrenches. I apologize for your inconvenience. I will send you a new free float barrel nut adapter at no cost. I don't currently have any inventory of adapters or wrenches, but will soon (see below). They went pretty quick. I will message you when I get more in.
As far as a group buy, I would be totally interested in doing that. Would like to start a roll call on who would be interested and the more the interest, the better the pricing. Cannot take ton off on them as they are fairly cheap to begin with and priced very competitively. All interested, please reply to this thread. As I mentioned, I am planning on making another batch soon (next few weeks) and will let everyone know when they are ready.
