For people researching felony gun laws today, 1968 is the pivotal federal legislative year.
National events accelerated legislation
ATF’s historical summary connects enactment to a period that included the assassinations of President John F. Kennedy, Senator Robert F. Kennedy and Dr. Martin Luther King Jr.
The GCA regulated interstate and foreign firearm commerce
The law strengthened federal licensing and transfer rules and created a broader national framework governing who could receive or possess firearms.
Felons became central prohibited persons
The modern concept of a federal firearm disability based on serious criminal convictions developed through the GCA and later amendments now codified in §§ 921, 922 and 924.
The law has been amended repeatedly
FOPA, Brady, NICS Improvement legislation and the Bipartisan Safer Communities Act all changed parts of the GCA framework without replacing it.
Where this fits in the larger timeline
This event is part of the History of Gun Laws in America series. Federal firearm law developed incrementally through constitutional amendments, taxation and commerce statutes, criminal prohibitions, background-check legislation and modern Second Amendment decisions.
