The main purpose of this legislation is to change how silencers, also known as firearm suppressors, are treated under U.S. law. The goal is to classify silencers as regular firearm accessories, which would reduce the regulatory burden on individuals who wish to own or use them. Key provisions of the legislation include several important changes. First, it amends the Internal Revenue Code to remove silencers from the list of items that require special tax treatment, effectively treating them like standard firearm accessories.
