Bill > HR631

This bill, known as the "Protecting Americans' Right To Silence Act of 2025" (or PARTS Act of 2025), proposes to modify the legal definitions of "firearm silencer" and "firearm muffler" in federal law. Specifically, the bill expands the definitions to include any device designed to reduce the sound of a portable firearm, encompassing both complete silencing devices and individual components of sound-reduction systems. The new definition covers devices that are intended to attach to a firearm either directly or through mounts, adaptors, or other attachments. The bill defines two main categories: (1) complete devices intended to silence or muffle a firearm's auditory report, and (2) outer tubes or primary structural components that house internal sound-reduction mechanisms. This legislation aims to provide a more comprehensive legal description of what constitutes a firearm silencer or muffler, potentially impacting how these devices are regulated under federal law.
