How it stays legal. Several states regulate ammunition sales — California and New York route them through licensed vendors with a background check, and Illinois, Massachusetts, New Jersey and Connecticut require a permit or ID card. Verify your state's rules before buying or selling. Rangium is a neutral listings venue — it never processes payment or ships firearms. See the marketplace rules, FFL transfer guide, and your state's firearm laws. Informational, not legal advice.
