Constitutional Hearing Protection Act

HR 3228, the Constitutional Hearing Protection Act, reclassifies firearm silencers as firearms under federal tax law and eliminates their separate registration under the National Firearms Act. It requires the Attorney General to destroy all existing federal silencer registration records within one year and preempts state laws that impose taxes, registration, or recordkeeping requirements on silencers. The bill defines "firearm silencer" and specifies that manufacturers must mark silencers on a "keystone part" with a serial number. This directly affects silencer owners, manufacturers, and state governments by standardizing federal regulation and removing state-level restrictions.
