    Have yet to drop in this barrel but I do expect an item to match perfectly to what is ordered on the pictures it shows HBAR branded on the barrel. Mine only says STAG ARMS 5.56 NATO 1-7T 4150 MPI. A small gripe but now for fear of Maryland's ever increasing AR-15 hatred I need to carry a copy of the packing slip to prove that it is indeed a HBAR.
