After years of lobbying by the NRA, Congress passed the Firearm Owners Protection Act of 1986, which, among other gun-friendly provisions, eased restrictions on interstate sales of firearms and expressly prohibited the federal government from creating a database of gun ownership.
A huge NRA triumph, the media declared. Some lawmakers said off the record that they would have voted against the act but feared retaliation from the gun lobby. And yet the Second Amendment fundamentalists were furious. The NRA endorsed the act even though it included a last-minute amendment pushed by gun-control advocates that further tightened the restrictions on machine guns and suppressors.
The bill expanded the GCA to prohibit civilian ownership or transfer of machine guns made after May 19, 1986, and redefining “silencer” to include parts intended to make silencers.
