## Summary

**This bill would **redefine 'firearm silencer' and 'firearm muffler'** in federal law to cover both complete sound‑reducing devices and the outer tubes or primary housing parts that enable sound reduction when attached to a portable firearm.** - Gun owners and hobbyists would see more aftermarket parts and DIY assemblies fall under the federal silencer definition, which could change how those items are regulated and enforced under Section 921. - Manufacturers and parts sellers would have standalone outer tubes or primary housings counted as silencers even if they lack internal sound‑reduction components, affecting what parts are treated as regulated items. - Law enforcement and courts would have a broader set of items that can be classified as silencers for prosecutions and compliance reviews, because attachments and adapters that enable use are explicitly included.
