 Plain-English summary Congressional Research Service

This bill amends the federal criminal code to prohibit certain conduct with respect to any part or combination of parts that is designed and functions to increase the rate of fire of a semiautomatic rifle but does not convert the semiautomatic rifle into a machine gun.

Specifically, it makes it a crime to manufacture, possess, or transfer such device: (1) in or affecting interstate or foreign commerce, or (2) that has been shipped or transported in interstate or foreign commerce.

An individual who knowingly violates the prohibition is subject to criminal penalties—a fine, a prison term of up to five years, or both.

Additionally, the U.S. Sentencing Commission must review and amend the sentencing guidelines and policy statements to provide an enhanced penalty if the device has been: (1) used, carried, or possessed during or in relation to a crime of violence or drug trafficking crime; or (2) unlawfully smuggled into or from the United States.
