They are the Ingram design that came four guns before the MAC 10.
I much prefer the M6 to the MAC. It has a fixed wood stock, a longer barrel and better sights, to name just three points of preference. Some also have the semi and full controlled by the trigger. Pull a little and shoot single shots, pull some more and fire FA. I like that system.
I was out shooting mine again last week, and was reminded how much I like it. It's in .45 ACP, but is more controllable than the Reising IMO. The rub is that magazines for the Ingram M6 are scarce and expensive.
