Following the 101 California Street shooting, the 1993 Waco Siege, and other high-profile instances of violent crime, the Act expanded federal law in several ways. One of the most noted sections was the Federal Assault Weapons Ban. Other parts of the Act provided for a greatly expanded federal death penalty, new classes of individuals banned from possessing firearms, and a variety of new crimes defined in statutes relating to immigration law, hate crimes, sex crimes, and gang-related crime. The bill also required states to establish registries for sexual offenders by September 1997.
Title XI-Firearms, Subtitle A-Assault Weapons, formally known as the Public Safety and Recreational Firearms Use Protection Act but commonly known as the Federal Assault Weapons Ban or the Semi-Automatic Firearms Ban, barred the manufacture of 19 specific semi-automatic firearms, classified as "assault weapons", as well as any semi-automatic rifle, pistol, or shotgun capable of accepting a detachable magazine that has two or more features considered characteristic of such weapons. The list of such features included telescoping or folding stocks, pistol grips, flash suppressors, grenade launchers, and bayonet lugs.
The ban took effect September 13, 1994 and expired on September 13, 2004 by a sunset provision. Since the expiration date, there is no federal ban on the subject firearms or magazines capable of holding more than ten rounds of ammunition.
Title VI, the Federal Death Penalty Act, created 60 new death penalty offenses under 41 federal capital statutes, for crimes related to acts of terrorism, murder of a federal law enforcement officer, civil rights-related murders, drive-by shootings resulting in death, the use of weapons of mass destruction resulting in death, and carjackings resulting in death.
