To amend the definitions of firearm silencer and firearm muffler in section 921 of title 18, United States Code, and for other purposes.

Bill 119 hr 631, also known as the "Hearing Protection Act," aims to amend the definitions of firearm silencer and firearm muffler in section 921 of title 18, United States Code. The bill seeks to reclassify firearm silencers and mufflers as accessories rather than firearms themselves, which would make it easier for individuals to purchase and possess these items.

Currently, firearm silencers and mufflers are regulated under the National Firearms Act, requiring individuals to undergo a lengthy background check and pay a $200 tax stamp in order to legally obtain them. The Hearing Protection Act would eliminate these requirements, making it more accessible for gun owners to protect their hearing while shooting.

Supporters of the bill argue that reducing the barriers to obtaining firearm silencers and mufflers would benefit public health by reducing noise pollution and preventing hearing loss among gun owners. However, opponents express concerns that deregulating these accessories could make it easier for criminals to obtain and use them in the commission of crimes. Overall, the passage of Bill 119 hr 631 would represent a significant change in the regulation of firearm silencers and mufflers in the United States, with potential implications for public safety and gun ownership rights.
