As bad as this order is, it should not affect the vast majority of surplus guns that are imported commercially. As I understand it, this only stops rifles that were sent by the US to its allies from coming back.
The US military rifle models available to the civilian market stopped with the Garand. The M14 and M16 can never be sold to civilians, even if converted to semi-automatic action. ("Once a machine gun, always a machine gun".) It specifically exempts the US gov't -- so those 87,000 Garands reported to be in storage in South Korea can still make their way back, eventually. The number of firearms effected fy this must be really, really, really small.
IMO, it's supposed to impress gun-grabbing liberals that he's actually doing something, which he is not. At worst, it's an attempt at "death by 1,000,000,000 paper cuts." (With 999,999,998 to go!)
Based on NICS numbers, Obama has been the best President for firearms sales in history. I think they're losing this one.
That would include M1 Garands and carbines, right? We could always use more of them.
