6mm arc made from leftover parts :-).

[willbird]

I had some stuff leftover from my 12.5" build that started out as a 10.5" build :-). I had a Brownells-Faxon 1/8 twist 14.5" 6mm arc barrel. So I went ahead and made an upper out of it. Pics coming later. But used Aero M4E1 upper, Brownells BCG, Aero quantum 12" rail, Larue MBT trigger. Dropped on a Aero M4E1 lower that has a Tailhook 2 brace on it.
