Listing Rules and Prohibited Items

Effective: 2026-09-11 • Last updated: 2026-09-28

These rules form part of the Terms of Use. We may remove any Listing that breaks them and suspend the account that posted it.

Listing rules

  1. One item per Listing; one Listing per item; correct category.
  2. Accurate title, description and condition. Photographs may show the item itself or the manufacturer's images of the same model.
  3. The price shown is the seller's own asking price, or “Call for Price”. No bidding, no “make an offer” language.
  4. Dealers may list firearms from their licensed inventory. A seller who is not a Federal Firearms Licensee may list only a firearm they personally and lawfully own, and is solely responsible for completing any sale lawfully, including through a licensee where the law requires it. GunMister does not verify any seller's licence status.
  5. Items regulated by the National Firearms Act (machine guns, suppressors, short-barrelled rifles and shotguns, "any other weapons", and destructive devices) may be listed only by a dealer licensed and registered to transfer them, and are transferred only through the ATF Form 4 (or Form 3 dealer-to-dealer) approval process. Transferable machine guns are those manufactured and registered with ATF on or before May 19, 1986. Pre-1986 and post-1986 dealer samples may be transferred only to licensed dealers who qualify to receive them. The buyer is responsible for meeting federal, state and local law.
  6. No language that suggests avoiding a required transfer, background check, licence or record (“no paperwork”, “no FFL”, “cash only no questions”, “private sale to avoid check”).
  7. No contact details or links in the Listing body other than the seller's storefront details.
  8. Buyers and sellers must not use contact details from the Site for any purpose other than the Listing enquiry.

Prohibited items (may not be listed)

  • Unregistered machine guns, auto sears, conversion devices, "switches", and any part, kit or instruction designed to convert a firearm to fully automatic fire. (Registered pre-1986 transferable machine guns are permitted when listed by a licensed dealer under the NFA transfer rules above.)
  • Unserialised or privately made firearms, unfinished frames and receivers, "80%" kits, and jigs or files for making them.
  • Firearms with removed, altered or obliterated serial numbers, and any stolen property.
  • Bump stocks, forced-reset triggers, and similar rate-increasing devices.
  • Explosives, grenades, rockets, destructive devices, and armor-piercing handgun ammunition.
  • Items that are unlawful to sell or possess in the seller's state, and any item advertised for shipment to a state where it is unlawful.
  • Body armor, except by Dealers to lawful purchasers in states where permitted.
  • Items subject to export controls advertised to persons outside the United States; no international shipping.
  • Instructions, plans or files for manufacturing any item on this list.
  • Anything else prohibited by federal, state or local law, and any listing for services rather than goods.
