§5. Restriction on bulk ammunition sales
This section prohibits persons licensed under the Gun Control Act (i.e., federal firearms licensees, or FFLs) from transferring to non-licensees (1) more than 100 rounds of .50 caliber ammunition or 1,000 rounds of any other caliber within any 5 consecutive days or (2) any ammunition without a transferee's written certification attesting compliance with those limits or if the transferor knows or has reason to believe the limits would be exceeded.
It further requires FFLs, for such transfers, to verify a transferee's valid photo ID (i.e., as defined in 18 USC 1028(d)), obtain a completed form including the certification and penalties notice, transmit the form to the Attorney General within 30 days for violation checks, and retain it for at least 2 years (with forms destroyed by the Attorney General after 60 days absent a criminal investigation). It criminalizes knowing false statements or fake IDs by transferees.
The section imposes penalties on violating FFLs of $50,000–$250,000 fines (with a 60-day sales ban for a second violation and license revocation for a third), up to 5 years imprisonment and $20,000–$50,000 fines on transferees for false statements, and $10,000 fines for recordkeeping failures. It also requires FFLs to post signage summarizing the restrictions and penalties (with $10,000 civil penalties per violation).
