How it stays legal. Most parts ship freely, but a serialized receiver or frame is a firearm under federal law and transfers like a complete gun — through an FFL where required. Unserialized or "80%" receivers can't be listed. Check your state's rules before buying magazines. 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.
