The purpose of this legislation is to change how silencers, also known as firearm mufflers, are classified under U.S. law. The main objective is to remove silencers from the definition of firearms in the Internal Revenue Code, which would make it easier for individuals to acquire and possess them. Key provisions of the legislation include several important changes. First, it amends the Internal Revenue Code to eliminate the classification of silencers as firearms, which means they would no longer be subject to the same strict regulations.
