Stop Online Ammunition Sales Act of 2023

This bill requires all ammunition sales to occur in person with identity verification, banning online or mail-order purchases for unlicensed individuals. It adds new licensing requirements for ammunition dealers and modifies existing firearm laws to explicitly include ammunition in sales, shipping, and recordkeeping rules. Licensees must report bulk sales of over 1,000 rounds to unlicensed buyers within one business day. The law directly affects ammunition sellers (both licensed and unlicensed) and buyers, making online ammunition transactions impossible without in-person verification.
