This proposed legislation aims to significantly liberalize the rules surrounding the interstate shipment of firearms and related components through the mail. A primary provision of this bill is the repeal of Section 1715 of title 18, United States Code , which previously prohibited the mailing of concealable firearms. This repeal would also apply to any cases currently pending under that section, ensuring its immediate effect. Additionally, the bill imposes strict limitations on the rule-making authority of the Postmaster General regarding the mailing of these items. It explicitly prohibits the Postmaster General from creating any rule that would either prohibit or materially impede the mailing of firearms, ammunition, or their components. Moreover, it prevents the Postmaster General from requiring the disclosure of sensitive information such as sales receipts, firearms transaction records, customer records, or the serial numbers of firearms or components as a condition for mailing.
