I bought a couple of boxes from him... also at the Timonium show.
They're relatively new, I believe. Located in Finksburg. When I first saw them at Timonium I mentioned the board and becoming an IP and he said he had already contacted the admin, or else was in the process of doing that.
He had a LOT more firearms there than he had at the Timonium show, which may be a sign he's growing his inventory rapidly.
