HR 4221
The Undetectable Firearms Modernization Act updates regulations to ensure firearms contain metal components, enhancing public safety and aiding law enforcement in detection efforts.
The Undetectable Firearms Modernization Act (HR 4221) aims to update and strengthen existing regulations concerning firearms that are undetectable by metal detectors. The bill seeks to enhance public safety by addressing the technological advancements in firearm manufacturing that allow for the creation of firearms that can evade detection.
The bill proposes several significant changes to current laws regarding undetectable firearms:
Definition Update: The legislation revises the definition of "undetectable firearm" to include any firearm that cannot be detected by walk-through metal detectors or similar devices.
Manufacturing Standards: It mandates that all firearms manufactured after a specified date must contain a certain percentage of metal components to ensure they are detectable.
Prohibition on Sale: The bill prohibits the sale, transfer, or possession of firearms that do not meet the new detection standards.
Penalties: It establishes penalties for manufacturers and individuals who violate the provisions of the act, including fines and potential imprisonment.
Research and Development: The bill encourages research into technologies that can enhance the detection of firearms and improve public safety measures.
The Undetectable Firearms Modernization Act would primarily impact:
Firearm Manufacturers: Companies producing firearms would need to comply with the new manufacturing standards.
Retailers: Gun shops and other retailers would be prohibited from selling undetectable firearms, requiring them to adjust their inventory.
Law Enforcement: Police and security agencies would benefit from enhanced detection capabilities, improving their ability to prevent crime.
General Public: The legislation aims to enhance public safety by reducing the risk posed by undetectable firearms.
Introduced Date: The bill was introduced in the House on June 27, 2025.
Committee Referral: Following its introduction, HR 4221 was referred to the House Committee on the Judiciary for further consideration.
The Undetectable Firearms Modernization Act represents a legislative effort to adapt firearm regulations to contemporary technological challenges. By establishing stricter standards for firearm detection, the bill aims to enhance public safety and reduce the risks associated with undetectable firearms. As the bill progresses through the legislative process, its implications for manufacturers, retailers, and law enforcement will be closely monitored.
