About StampSwap

StampSwap is the peer-to-peer marketplace for used NFA items — suppressors, SBRs, SBSs, and AOWs. Buy directly from other owners at a fraction of retail, or sell the items you no longer need. No dealer markup. No middleman.

Why StampSwap exists

On January 1, 2026, the $200 NFA tax stamp dropped to $0. Overnight, private party transfers became financially viable for the first time. A used suppressor that cost $800 new can now change hands for $400-500 — without a $200 stamp eating into the deal for both sides.

But there was no dedicated marketplace. Used NFA items were scattered across forum classifieds, Facebook groups (that constantly get banned), and word of mouth. Buyers couldn't search by manufacturer, caliber, or price. Sellers had no way to build reputation across transactions.

StampSwap fills that gap — a purpose-built platform where NFA owners can trade with compliance tools, transfer guidance, and community trust.

What we do

Our role is clear

StampSwap is a listing platform. We connect buyers and sellers and give you the tools to transfer safely. Here's what that means in practice:

• •We are not an FFL — we never take possession of NFA items
• •We don't process payments — we recommend GunTab for secure escrow
• •We don't submit ATF forms — our Form 4 guide helps you do it yourself

Think of us like Reverb.com for NFA items — a purpose-built marketplace with the tools and trust features this community has been missing.
