A bill to amend title 18 of the United States Code to increase certain penalties for gun control offenses and to allow the United States to obtain appellate review of certain sentences relating to gun control offenses.

Amends the Gun Control Act of 1968 to require that anyone using or carrying a firearm during the commission of any felony prosecutable in Federal court shall, in addition to the punishment provided for such crime, be sentenced to a term of imprisonment of not less than two nor more than ten years.

Requires in the case of a second or subsequent conviction the imposition of a term of imprisonment of not less than five nor more than 25 years. Stipulates that in such case the sentence: (1) may not be suspended; (2) may not include probation; and (3) may not run concurrently.

Authorizes the United States to appeal a suspended or probationary sentence imposed in the case of a first conviction.
