Common questions
The stuff you actually want to know before listing or buying.
30-50% less than retail. A suppressor that costs $800-1,200 new from a dealer typically sells for $400-700 from a private seller. With the tax stamp now $0, there's no hidden cost eating into those savings.
Yes. Private party NFA transfers are legal in 42 states. The $200 tax stamp dropped to $0 on January 1, 2026. StampSwap is a listing platform — we connect buyers and sellers. We never sell, buy, transfer, or take possession of any items. Check your state.
For in-state transfers between individuals — no. For interstate transfers, the item goes through a licensed FFL/SOT in the buyer's state. Find a dealer near you.
StampSwap does not handle payments. Buyer and seller arrange payment directly. We recommend GunTab for escrow protection — funds are held until both parties confirm. You can also use money orders, cashier's checks, or cash for local deals.
eForms individual registrations: 10-15 days. Trust/entity: 25-30 days. Paper Form 4 takes much longer. We strongly recommend eForms. StampSwap's Form 4 prep tool auto-fills your ATF 5320.4 from transaction data, and our tracker lets you monitor the process from filed through approval to item transferred.
Your first listing is free. Free accounts get 1 active listing. If you want to list more, plans start at $5.99/mo for 10 listings. Optional bumps ($1.99) and featured placement ($4.99) are available but never required. See pricing.
This is exactly why we built reputation tracking. Every completed transfer results in a review. Buyers and sellers build transaction history over time. If you use GunTab for escrow, funds are protected if a deal falls through. We also have a reporting system for bad actors.
