The Armed Career Criminal Act of 1984 (ACCA) is a United States federal law that provides sentence enhancements for felons who commit crimes with firearms if they are convicted of certain crimes three or more times. If a felon has three or more prior convictions for offenses that are "violent felony" offenses or "serious drug offenses," the Act provides a minimum sentence of fifteen years imprisonment, instead of the ten-year maximum prescribed under the Gun Control Act. The Act provides for an implied maximum sentence of life imprisonment.
