This design is a 1940s variation of an 1890s design. Nothing like the scary semi-auto rifles that the US prohibitionists fear. And yet, can you imagine them being OK with you or I having this rifle without interference?
Their end-game is less to restrict specific arms than to restrict people who aren’t them or their flunkies — in short, to expand the concept of “prohibited person” to encompass all of their political opponents and all the neutrals. That’s how it is in other totalitarian countries: the high-ranking supporters of the ruling party get guns, the rest do not. It was that way in 1930s Italy and Germany and USSR, and it is that way in New York City now.
