Step 1: List or Browse
Create a listing with photos, specs, and your asking price — or browse existing listings filtered by type, caliber, manufacturer, price, and location.

Message sellers, make offers, and agree on terms — all through our secure in-app messaging system. No need to share personal contact info until you're ready.
Step 3: Prepare the Transfer
Use our Form 4 guide to prepare all required documents and paperwork. Our state compliance checker ensures the transfer is legal in your jurisdiction.
Step 4: Complete & Review
Track the ATF approval process, complete the transfer, and leave a review. Build your reputation for future transactions.
