fyi, they were used in both episodes of the war.
they are chinese guns if you did'nt know.
i have the riot version, same gun just without the heat shield, bayo lugs or sling swivels.
have it about 8 or 9 years now....never an issue, other than the rough action that smoothed out after a few hundred rounds. slam fired more than a few shells through it already.
never heard of the hammer bite issue, though i guess it is possible.
was trap shooting with it the other week.....that got the looks and me all of six birds.
