Actually, I don't think it means that, although I may be wrong. I think the statement Military surplus firearms sold under "Lend Lease" and similar arms assistance programs cannot be imported, as these weapons are >>prohibited<< by the Arms Export Control Act of 1976 (22 USC 2778) means that NO surplus firearms sold under "Lend Lease" may be imported, regardless of importer status.
