Sorry, my bad, they were in fact restricted - I throw myself on the mercy of CGN. I had thought that the only reason that anyone in the gun business would be so hyper over an ACR would be that it was non-res. Apparently being on CGN makes you 'cutting edge' as I had already handled a couple of ACR's (1 non-res conversion), and the store thought they were totally unobtanium, restricted or otherwise. Again, my abject apologies to all.
