Not as advertised - Daniel Defense AR Bolt Assembly 5.56 NATO / 300 Blackout

The last one I bought was marked with “C158 HPI MPI” because they were made with C158 steel. They also were high pressure tested then magnetic particle tested hence the stamps that should be in the bolt. These could be Bear Creek Arsenal and nobody would know. I bought a few last year and they had the marking you would expect from Daniel Defense.
