The new orders ban Americans from buying weapons that the US military has provided to foreign governments. Around 250,000 guns, including assault rifles, have been re-imported back into the US since 2005, according to White House figures.
Missouri, a Republican state, is expected to move next month to forbid national gun laws from being enforced within the state's borders.
The bill would make it a crime for FBI agents or others to enforce federal gun laws and would allow citizens to sue any law enforcement officer who arrested them.
It would also make it illegal to publish the names of gun owners as some local newspapers have done in an effort to shame opponents of gun control.
The law is almost certain to be struck down by the court as it appears to violate the federal government's power to make law as well as the right to free speech guaranteed by the US Constitution.
