Full-Auto Firearms and Machine Gun Parts
By listing a full-auto firearm, machine gun, or machine gun part on GunBroker.com, you agree to comply with the following requirements. Listings that do not comply with these requirements may be removed without notice.
Full-Auto Firearms
All machine guns and other full-auto firearms must:
- Be transferred in accordance with the National Firearms Act (NFA) and all applicable federal, state, and local laws.
- Be clearly identified as a machine gun or full-auto firearm within the item description.
- Include language stating that the item will only be shipped to a properly licensed Federal Firearms Licensee (FFL) with the appropriate Special Occupational Tax (SOT) status.
Full-Auto Parts
Machine gun parts, including but not limited to auto sears, replacement sears, and other components designed for use in machine guns, are subject to the same GunBroker restrictions.
Although certain machine gun parts may not be regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), GunBroker requires that these items:
- Be clearly identified in the listing.
- Include language stating that the item will only be shipped to a properly licensed FFL/SOT holder.
Prohibited Items
The following items are prohibited and may not be listed on GunBroker:
- Instructions, manuals, guides, or informational materials describing how to convert a firearm to fully automatic operation.
- Instructions, manuals, guides, or informational materials describing how to manufacture a silencer or suppressor.
- Full-auto conversion kits.
- Any item intended to unlawfully convert a firearm into a machine gun.
NFA / Title II Item Listing Requirements
What Are NFA / Title II Items?
NFA (National Firearms Act) items, also known as Title II firearms, are firearms and devices regulated under federal law. Examples include:
- Suppressors / silencers
- Short-barreled rifles (SBRs)
- Short-barreled shotguns (SBSs)
- Machine guns
- Destructive devices
- Any Other Weapons (AOWs)
Current ATF Enforcement Policy
On October 9, 2026, ATF announced nationwide nonenforcement of specified NFA making, transfer-approval and registration requirements for suppressors, short-barreled rifles, short-barreled shotguns and firearms classified as any other weapons. Under that current policy, the federal government will not prosecute covered transfers for violations of the specified NFA provisions. The policy extends beyond the parties protected by the court injunction. DOJ also said it would not appeal the decision.
The policy does not repeal the NFA or create a permanent exemption. It does not protect violations of other federal, state or local requirements. Machine guns and destructive devices remain subject to their existing NFA requirements. Applicable business licensing and SOT obligations and Gun Control Act requirements continue.
ATF continues to process voluntary NFA applications. Before committing to a purchase, confirm the proposed transfer process with the seller and receiving FFL. GunBroker listing and transfer requirements continue to apply. Review the ATF guidance and frequently asked questions for current information.
Registration and Future Enforcement Risk
Federal law, regulations and enforcement guidance can change. A future administration could reverse the enforcement policy, and legislation or a court ruling could also change the legal position. ATF says there is no automatic grandfathering for unregistered NFA items if enforcement resumes. Continued possession or later transfers could carry criminal penalties and forfeiture risk. Later registration generally is unavailable; an amnesty or other relief is discretionary and is not guaranteed.
To reduce reliance on the current policy, you may elect to use the voluntary NFA registration process where available. Ask the responsible FFL to confirm the item's eligibility and complete the appropriate registered-transfer process before you take possession. Registration may reduce the risk from a policy reversal; it does not guarantee protection from future changes in law or override state and local restrictions.
A purchase receipt, dealer record or registration to a prior owner does not register the item to you. Confirm registration to the intended individual or legal entity and retain the records. Review the consequences with the responsible FFL and qualified counsel before withdrawing a pending application or requesting deregistration.
Listing Requirements
1. FFL and SOT Requirements
To list NFA items on GunBroker, sellers must possess a valid Federal Firearms License (FFL).
Where required by law, sellers must also hold the appropriate Special Occupational Tax (SOT) designation:
- Class 1 SOT – Importers
- Class 2 SOT – Manufacturers
- Class 3 SOT – Dealers
Sellers who do not possess the required licenses and tax status may not list NFA items.
2. Category Selection
All NFA / Title II items must be listed in the appropriate NFA-specific category.
Listings placed in incorrect or non-NFA categories may be removed.
GunBroker will continue to use its existing NFA categories and FFL routing requirements. ATF's current enforcement policy does not itself change GunBroker's existing platform processes.
3. Listing Content Requirements
Listings must clearly identify the item as an NFA / Title II item and include:
- Manufacturer
- Model
- Caliber or gauge (if applicable)
- Overall condition
Suppressor listings should also include:
- Thread pitch or mounting system compatibility
- Caliber rating
- Any applicable mounting accessories
Listings must accurately describe the item and the proposed transfer process. Sellers must not claim permanent exemption, automatic grandfathering, guaranteed future registration or legality in every jurisdiction. If a listing proposes a transfer without NFA registration or approval, it must explain that the seller and transferring FFL must determine whether that process is permitted for the particular transaction under applicable law and GunBroker policy. It must also direct buyers to the registration-risk information in this article.
4. Transfer Requirements
GunBroker requires NFA transactions to be handled through an appropriately licensed FFL/SOT dealer and in compliance with applicable federal, state and local requirements. Existing NFA category and dealer-routing requirements remain in place. The October 9 ATF policy does not authorize users to bypass GunBroker requirements or ship directly to an unlicensed buyer where an FFL transfer is required.
Before bidding or purchasing, confirm that the receiving dealer accepts the particular item and proposed transfer process. For a registered transfer, the responsible parties must obtain the appropriate approvals for each transfer before that transfer occurs. Shipment to the receiving dealer and the dealer's later transfer to the buyer are separate steps. A seller's prior registration or a dealer-to-dealer approval does not establish registration to the ultimate buyer.
Any proposed transfer relying on ATF nonenforcement rather than NFA registration must be evaluated by the seller and transferring FFL for the actual parties, item and jurisdictions. GunBroker does not determine transaction-specific legal eligibility or verify entitlement to court-ordered relief. Dealer selection, payment, license receipt and order-status updates are not confirmation of NFA approval or authorization to release the item. Processing time depends on the selected process and applicable requirements.
Common Reasons NFA Listings Are Removed
NFA listings may be removed for reasons including, but not limited to:
- Missing or invalid FFL/SOT credentials
- Listing in the wrong category
- Violation of GunBroker policies
- Federal, state, or local legal restrictions
- Incomplete or inaccurate listing information
- Misleading claims about legal eligibility, registration, permanent exemption, grandfathering or future registration, or failure to explain the seller's and transferring FFL's responsibility for evaluating a proposed unregistered transfer.
If Your NFA Listing Was Removed
If your listing was removed:
- Verify that your FFL and, where applicable, SOT status are current and on file with Master FFL.
- Confirm that the item was listed in the correct category.
- Review the listing for compliance with all GunBroker policies.
- Correct any deficiencies and relist the item, if permitted.
- Contact GunBroker Support if you believe the removal occurred in error.
State and Local Restrictions
State and local laws may differ from the federal policy. They may prohibit an item or require compliance with federal law or NFA registration. Federal nonenforcement does not prevent state or local prosecution. The legality of a registered transfer may differ from an unregistered transfer involving the same type of item. Voluntary NFA registration does not override a state or local prohibition.
Before listing, bidding, shipping or accepting delivery, the parties and participating FFLs must determine which requirements apply to the actual transaction. The presence of a listing, an available dealer or an enabled checkout option does not establish that the item may lawfully be transferred or possessed in the buyer's location.
GunBroker's acceptance of a listing, processing of a marketplace transaction, or routing of an item to an FFL does not constitute approval of the transaction or a determination that any exemption or injunction applies.
