Federal Assault Weapons Ban

Part of the Violent Crime Control and Law Enforcement Act of 1994. It produced a 10-year federal ban on the manufacture of new semi-automatic assault weapons with certian specifications. Firearms with specific features were defined as assault rifles. Including the AR-15, certain versions of the AK-47, the TEC-9, the MAC-10 and the Uzi, several of which had become the preferred weapon of violent drug gangs. The act also bans large-capacity ammunition magazines, limiting them to 10 rounds. The law did not apply to weapons that were already in legal possession.
Because this law was not renewed by congress in 2004, the ban was lifted.
