I was watching some file film yesterday of 2 Navy MP’s and one seemed to have a Saiga 12 ga shotgun as his main weapon. I had never seen a Saiga with a tube however. I’s possible that it was a Benelli. The reciever looked like an AK however.If I see it again I will try to freeze it and look closer.
The Benelli M4 Super 90 has been adopted by the Navy/Marines as the M1014 - the receiver looks a lot like that of an AK.
