ATF's October 9 NFA Open Letter: What Changed and What Didn't for FFL and SOT Dealers

On October 9, 2026, ATF issued an open letter changing how it handles short-barreled rifles (SBRs), short-barreled shotguns (SBSs), silencers, and any other weapons (AOWs). ATF no longer requires its approval to make or transfer these items, and it no longer requires them to be registered in the National Firearms Registration and Transfer Record (NFRTR).

That is a large operational shift for FFL and SOT dealers. It is also narrower than some headlines suggest. This is enforcement discretion, not a repeal of the National Firearms Act. Here is what changed, what didn’t, and what dealers still do. This article is general information, not legal advice.

How we got here

In the One Big Beautiful Bill Act (Pub. L. 119-21), Congress set the making and transfer taxes on these items to $0. In Silencer Shop Foundation v. ATF (No. 6:25-CV-056-H, N.D. Tex., Aug. 5, 2026), a federal court issued an injunction that covered only the plaintiffs. DOJ said it will not appeal, and ATF then extended the policy nationwide through the open letter.

What changed

Effective October 9, 2026, for SBRs, SBSs, silencers, and AOWs:

• ATF no longer requires ATF approval to make or transfer these items.
• ATF no longer requires NFRTR registration for them.
• The policy applies uniformly, not only to the plaintiffs in the court case.
• Forms 1, 2, 3, and 4 are still accepted, but on a voluntary basis.

ATF’s FAQ adds more detail. ATF will not enforce 26 U.S.C. 5861(j), which covers interstate transport of unregistered items, and it will not enforce the NFA marking requirement for these items. ATF also says it will not enforce 18 U.S.C. 922(b)(4) in the interim while regulations are pending.

What didn’t change

Several important pieces stay in place:

• The NFA itself. This is enforcement discretion. The statute has not been repealed.
• Machineguns and destructive devices. These remain fully regulated under the NFA, including the $200 tax. The open letter does not cover them.
• SOT status. Those engaged in the business still need Special Occupational Tax status.
• The Gun Control Act. Prohibited-person rules, recordkeeping, and the Form 4473 and NICS steps all still apply.
• Some NFA provisions still enforced. ATF still enforces 5861(h) and 5861(k), which cover obliterated serial numbers and illegal import.
• Form 20 for SBRs and SBSs. ATF Form 5320.20 is still required for interstate transport of SBRs and SBSs.

What dealers still do

ATF’s guidance is to process silencers and AOWs like other GCA firearms. In practice:

1. Run the 4473 and NICS. Every transfer to an unlicensed person still goes through these steps.
2. Watch residency. Sales to unlicensed persons are generally limited to residents of the FFL’s state.
3. FFL-to-FFL interstate transfers. For silencers and AOWs, no Form 3 is required between licensees. Filing one is voluntary.
4. Out-of-state buyers. Unlicensed persons can’t transfer to out-of-state residents. An out-of-state sale still goes through an FFL in the buyer’s state.
5. SBRs and SBSs crossing state lines. Keep the Form 20 step in place for interstate transport.
6. Keep your records. GCA recordkeeping is unchanged.

For online sellers, the shipping pattern stays familiar: firearms sold online still ship to a dealer. Automatic FFL lets shoppers pick that dealer at checkout on BigCommerce, WooCommerce, and Magento, and on Shopify for ammo only. It does not handle NFA or SOT matters or determine whether a sale is legal in a given state.

State law

State and local laws did not change. Many states still ban some of these items or require federal registration to possess them, and a federal enforcement change does not override that.

Federal law also still ties dealer transfers to state law. Under 18 U.S.C. 922(b)(2), an FFL still can’t transfer a firearm in violation of state or local law, and ATF’s letter notes that this covers these items. ATF also says it is unclear whether state courts will apply the 926A safe harbor for interstate transport to unregistered NFA items.

Some states are responding on their own. On October 12, Mississippi Attorney General Lynn Fitch said Form 4 is voluntary for Mississippians under current ATF guidance. That is one state attorney general’s view. It does not speak for other states. Check your state’s current law, and your buyer’s, before any transfer.

De-registration, and why the FAQ urges caution

ATF’s FAQ says owners can request removal of an item from the NFRTR through NFAFAX@atf.gov. The FAQ is also clear about the risks. Once an item is removed, it can’t be re-registered without an amnesty from the Attorney General, and nothing is grandfathered if the policy reverses.

The FAQ describes how that could happen: the injunction could be dissolved or overturned, or DOJ could rescind the guidelines. In that case, unregistered items could become contraband, with felony penalties. This is not a recommendation either way. It is a reason to read the FAQ carefully and talk to counsel before anyone acts.

What to watch

• The ATF FAQ. It was last updated October 13, 2026, and it is the most current source on how ATF is applying the policy.
• Regulations. ATF’s interim non-enforcement of 922(b)(4) is tied to pending regulations. Watch for proposed or final rules.
• Court developments. Any change to the Silencer Shop Foundation injunction could affect the policy.
• DOJ guidance. The FAQ notes DOJ could rescind the guidelines.
• State action. Expect more state officials to issue their own guidance, in both directions.
• Manufacturers. ATF’s FAQ notes that silencer makers must register with the State Department under ITAR before November 20, 2026.

This is not a permanent change, and it doesn’t mean there are no rules. It is a federal enforcement policy that can change, and it sits on top of a GCA framework and state laws that have not moved.
