Don't know about commercial knock offs but the original M1 Carbine didn't have bayonet lugs. They came about later in the war. (WWII).
However any non-bayonet carbines that went to the rebuild shops were fitted with the lugs.
I don't know about New York gun laws, but I think it's unpatriotic to ban a piece of history like the M1 Carbine or M1 Garand.
