This legislation aims to prohibit the United States Postal Service (USPS) from taking any action on a specific proposed rule related to the mailing of firearms. It prevents the USPS from finalizing, implementing, or enforcing the rule titled "Revised Mailing Standards for Firearms," which was published in the Federal Register on April 2, 2026. The bill's scope extends to any substantially similar rule that might be proposed in the future. Its primary purpose is to maintain current mailing standards for pistols, revolvers, and other firearms capable of being concealed on the person , effectively blocking new restrictions or changes in this area.
