Which would obviously include all the Evil Black Rifles and SKS-pattern rifles, but as well all the M-1 Garands out there.
You might want to study up on the rifles a little, Most SKS's and Garand's have fixed magazines... not detachable.
Although I wouldn't expect a gun grab to end there, the SKS and Garand are two of the most dependable surplus rifles out there... they would be way up on a "ban list" just because there are so many in circulation.
