StampSwap is a marketplace platform that connects buyers and sellers of NFA items. StampSwap is not a Federal Firearms Licensee (FFL), does not take possession of any NFA items, does not process payments for NFA transactions, and does not facilitate or approve ATF Form 4 transfers. All NFA transfers must comply with federal, state, and local laws. Users are solely responsible for ensuring legal compliance.
