House lawmakers have passed a 10-year extension of the Undetectable Firearms Act.
The law bans the manufacture, possession and sale of firearms that can go undetected by metal detectors and requires handguns be manufactured in the shape of a gun so they can be seen on x-ray machines.
With the recent developments in 3D printing technology this extension may cover new ground.
The Obama Administration and congressional democrats want the extension to also deal with potential loopholes for 3D printed firearms.
The bill will now head to the senate for approval.
Some Senate democrats are pushing to add provisions to address these new technologies. However, since the law expires on Monday the Senate may pass the House version and address any other updates to the law next year.
This was first enacted during the Reagan administration in 1988 and reauthorized under presidents Clinton and George W. Bush.
