How it stays legal. Some states and localities regulate ammunition sales — background checks, ID or permit requirements, and shipping limits vary. 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 and your state's firearm laws. Informational, not legal advice.
