The NFA Ruling and ATF's October 2026 Guidance: What Changed for Suppressors, SBRs, and SBSs

This article reflects federal and state law as of October 2026. Laws in this area change frequently; verify current law in your state before relying on it. This is general information, not legal advice.

When we first wrote about the August 2026 National Firearms Act ruling, the honest answer to "can I buy a suppressor without a Form 4?" was "only if the court's injunction covers you." That answer is now out of date. On October 9, 2026, ATF published an open letter and a set of FAQs saying it will no longer enforce the NFA's approval and registration requirements for suppressors, short-barreled rifles (SBRs), short-barreled shotguns (SBSs), and "any other weapons" (AOWs), for anyone, anywhere in the country.

That is a large practical change. It is also narrower and more fragile than a lot of the commentary suggests. The statute has not been repealed, machine guns are untouched, the Gun Control Act still governs every dealer sale, and state law is exactly where it was. This guide walks through each piece.

The short version

• What ATF stopped enforcing: the requirement to get ATF approval before making or transferring a suppressor, SBR, SBS, or AOW; the requirement to register those items in the National Firearms Registration and Transfer Record (NFRTR); the NFA marking requirement; and most of the NFA's criminal prohibitions on unregistered items of those types.
• Effective date: October 9, 2026.
• Who it covers: everyone, not just the plaintiffs in the Texas case. ATF extended the court's reasoning nationwide as a matter of enforcement discretion.
• What still applies: the full NFA for machine guns and destructive devices; special occupational taxes for NFA businesses; the NFA bans on items with obliterated serial numbers or that were illegally imported; Form 4473 and background checks for dealer sales; prohibited-person rules; the federal permission requirement (Form 20) to take an SBR or SBS across state lines; and every state and local law.
• Why it could change: ATF's own FAQs say enforcement could resume if Congress imposes a new tax, the injunction is dissolved or overturned, or the guidance is rescinded.

How we got here: a $0 tax and a taxing-power case

The NFA, enacted in 1934, has always been structured as a tax law. Making or transferring a regulated item required paying a tax (historically $200), and the registration and approval machinery existed to collect it.

The One Big Beautiful Bill Act (Pub. L. No. 119-21), signed July 4, 2025, set a $0 making and transfer tax for every NFA category other than machine guns and destructive devices, effective January 1, 2026, according to the Congressional Research Service. ATF's October letter confirms that the $200 tax remains on machine guns and destructive devices.

Gun-rights groups then argued that once the tax was gone, the registration and approval requirements had nothing left to stand on. On August 5, 2026, U.S. District Judge James Wesley Hendrix of the Northern District of Texas agreed in Silencer Shop Foundation v. ATF, No. 6:25-cv-056-H, which was consolidated with Jensen v. ATF. As ATF summarizes the ruling in its October 9 open letter, the court held that:

• With the tax at $0, the NFA's registration and transfer provisions for those items were "no longer an exercise of Congress's taxing power," because they no longer served to raise revenue.
• The commerce power could not rescue them, because Congress did not rely on that power when it enacted the NFA in 1934.

The decision turned on Congress's enumerated powers, not the Second Amendment; the court did not decide the Second Amendment claims. That matters later: it is why a new tax from Congress could, at least in theory, restore the old system.

The injunction took effect in mid-August after a seven-day stay expired (ATF dates it to August 12). It protected only the parties: the named plaintiffs, members of the plaintiff organizations, customers of the commercial plaintiffs, and the plaintiff states as governments, according to a Wiley Rein client alert from the firm that represented plaintiffs. AOWs were covered only for the Silencer Shop Foundation plaintiffs, not the Jensen plaintiffs. Our original article described that party-limited situation.

The appeal that did not happen

The government could have appealed to the Fifth Circuit. It did not. Solicitor General D. John Sauer told Senate Judiciary Committee Chairman Chuck Grassley in a letter dated September 24, 2026 that the Department of Justice "has determined not to file an appeal," and that letter was filed with the court on October 1, according to AmmoLand. The deadline to appeal passed on October 5.

A district court judgment that is not appealed still binds only the parties to the case. It does not bind other federal courts, and ATF's own FAQs say so. The nationwide change comes from ATF's decision about how to use its enforcement resources, not from the judgment itself.

What ATF's October 9 guidance says

ATF Director Robert Cekada signed the open letter, and ATF posted companion FAQs on its Update to NFA Transfer Guidance page. The letter notes that the injunction "applies only to the plaintiffs," then extends the same treatment to everyone. Here is what it does.

Approval, registration, and marking for $0-tax items. Individuals no longer need ATF approval before making or transferring an SBR, SBS, suppressor, or AOW (as defined in 26 U.S.C. § 5845). Those items no longer need to be registered in the NFRTR or carry NFA markings, and businesses no longer need to register newly made items within 24 hours. ATF will still accept Form 1, Form 2, Form 3, and Form 4 filings from anyone who wants to file voluntarily.

Unregistered-item crimes, with two exceptions. ATF will not enforce the NFA's prohibitions on making, receiving, transferring, or possessing unregistered items of these types, including the ban in 26 U.S.C. § 5861(j) on transporting an unregistered NFA firearm in interstate commerce. It will keep enforcing § 5861(h) and (k), which cover NFA firearms with obliterated serial numbers and those imported illegally. Note that the § 5861(j) change is NFA-side only; the Gun Control Act rule for SBRs and SBSs discussed below still applies.

Dealer sales of SBRs and SBSs. Under 18 U.S.C. § 922(b)(4), a licensed dealer may not sell an SBR or SBS to anyone "except as specifically authorized by the Attorney General consistent with public safety and necessity." For decades, an approved NFA transfer was that authorization. With approvals no longer required, no other mechanism exists yet. ATF says it is working on new regulations and, in the meantime, "will not enforce the provisions in 18 U.S.C. § 922(b)(4)."

Business-to-business transfers. Transfers between special-occupational-taxpayer licensees no longer require an approved Form 3, though Form 3s may still be filed.

What did not change

This is the part to read twice.

Machine guns and destructive devices. These keep the $200 tax and every NFA requirement. In Director Cekada's words, "the injunction does not disturb the NFA's application to machineguns and destructive devices," and "all NFA provisions still apply" to them, as The Reload also reported. Nothing about machine-gun transfer or possession rules has moved.

Special occupational taxes. Anyone in the business of manufacturing, importing, or dealing in NFA items still owes the applicable special occupational tax, and ATF says it will keep enforcing the rule against doing that business without paying it.

The Gun Control Act, in full. Suppressors, SBRs, SBSs, and AOWs are still "firearms" under federal law, and ATF's FAQs say "all GCA requirements still apply." In practice that means:

• A dealer selling one of these items to an unlicensed buyer completes a Form 4473 and runs a background check through NICS unless an exemption applies.
• Dealers keep acquisition and disposition records.
• Prohibited persons (felons, people under certain restraining orders, and the other categories in 18 U.S.C. § 922(g) and (n)) still may not receive or possess them.
• With limited exceptions, dealers may sell these items only to residents of the state where the dealer is licensed. For the general out-of-state purchase rules, see our guide to interstate firearm purchases and FFL transfers.

Form 20 for SBRs and SBSs crossing state lines. This is the requirement most likely to trip people up. Separate from the NFA, the Gun Control Act at 18 U.S.C. § 922(a)(4) makes it unlawful for an unlicensed person to transport a destructive device, machine gun, short-barreled shotgun, or short-barreled rifle in interstate commerce except as authorized by the Attorney General. ATF's FAQs state that individuals must still file a Form 20 (ATF Form 5320.20, the Application to Transport Interstate or to Temporarily Export Certain NFA Firearms) before transporting an SBR or SBS across state lines, even if the item is unregistered. Suppressors and AOWs are not listed in § 922(a)(4), so this particular requirement does not reach them.

State and local law. ATF's letter states that the injunction and the policy do not change state or local laws, and that dealers still may not transfer a firearm in violation of state or local law under 18 U.S.C. § 922(b)(2). The letter also calls it "unclear" whether state courts will apply the federal safe-passage provision for travelers, 18 U.S.C. § 926A, to someone carrying an unregistered item through a restrictive state, and advises caution.

State law: where the real risk now sits

For most buyers, the federal question has gotten simpler and the state question has gotten harder. State NFA laws generally fall into three groups.

States that ban the items outright. These bans never depended on federal registration and are unaffected by the ruling or the guidance. As commonly tallied, eight states and the District of Columbia prohibit civilian suppressor possession: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. Short-barreled rifle and shotgun rules vary separately. California, for example, generally makes it a crime to make, sell, or possess an SBR or SBS under Penal Code § 33215, subject to narrow exceptions. Check SBR and SBS law on its own; do not assume it tracks your state's suppressor law. Our state-by-state suppressor guide covers the suppressor bans in more detail.

States whose law ties legality to federal compliance or registration. This is the group to worry about. Many state statutes make possession of a suppressor or short-barreled firearm a crime unless the item is registered under the NFA, or unless the owner is in compliance with federal law. Two examples:

• Washington's RCW 9.41.190 prohibits possession of short-barreled rifles and shotguns, but exempts short-barreled rifles when "the person is in compliance with applicable federal law." That exception does not extend to short-barreled shotguns. Whether possessing an unregistered SBR under a federal non-enforcement policy counts as "compliance" is a question for Washington authorities and courts, not ATF.
• Montana Attorney General Austin Knudsen issued guidance on August 27, 2026 stating that possession of an unregistered silencer remains a felony under Montana law, that Montana's exemption for short-barreled shotguns depends on a valid federal tax stamp, and that "Montana law still requires suppressors to be registered with the ATF if used for hunting." That guidance predates ATF's October 9 letter. The Montana DOJ notes that bills addressing the issue have been introduced ahead of the 2027 legislative session.

ATF's FAQs put it plainly: ATF cannot say whether an unregistered item is lawful under any particular state's law. Check with your state attorney general's office or a lawyer in your state.

States with no state-level NFA law. In these states, a dealer can generally transfer a suppressor on a Form 4473 and a background check, with no Form 4 and no wait beyond the NICS check, subject to any other state requirements such as waiting periods or permits. Dealer SBR and SBS sales depend on the § 922(b)(4) non-enforcement described above, and dealer practices may vary.

Voluntary registration, removal, and why there is no undo button

You can still register. ATF will maintain the NFRTR and process forms for anyone who files voluntarily. In a state whose law depends on federal registration, voluntary registration may be the only way to stay clearly within the state's exception. That is a judgment to make with a lawyer in your state.

If you already own registered items, ATF says you can ask to have them removed from the registry by writing to NFAFAX@atf.gov. Before you do, read ATF's warning carefully: once an item is removed, it cannot be re-registered unless the Attorney General declares an amnesty. The NFA permits an amnesty period of up to 90 days, but the Attorney General is not required to offer one.

The same logic applies to new, never-registered items. ATF's FAQs say there are "no provisions that would automatically grandfather unregistered NFA firearms." If enforcement resumes, an unregistered NFA firearm is contraband under the NFA, and ATF notes that unregistered possession, transfer, or receipt can carry felony penalties and forfeiture.

Consider a typical scenario: a buyer in a state with no state NFA law picks up a suppressor on a 4473 in October 2026 and does not register it. Two years later, Congress restores a nominal tax and the injunction is dissolved. Whether that buyer can register at that point depends on whether the Attorney General offers an amnesty window. Nothing in current law guarantees one.

Why this is enforcement policy, not repeal

Every protection described above rests on one of two things: a district court judgment that binds the parties to it, and an agency decision about what to prosecute. Neither changes the text of the NFA. ATF's FAQs list the circumstances that could bring enforcement back:

• Congress imposes a new making or transfer tax on these items, which would restore the taxing-power footing the court found missing.
• A court dissolves or overturns the injunction. Separately, other federal courts are not bound by the Texas judgment and could reach a different conclusion in another case.
• The Department of Justice rescinds the guidance. A future administration, or this one, could reverse a discretionary enforcement policy without new legislation.

That does not make the current guidance unreliable for today's purposes. It means a decision to skip registration is a bet on the future that you make now, and the downside if it goes wrong is serious.

Litigation over the injunction's reach is also still moving. As of early October 2026, nine plaintiff states had asked the Texas court to clarify whether the injunction covers all relevant transfers within their borders, and a separate challenge in Missouri federal court (Brown v. ATF, consolidated with a suit by Missouri and other states) had a status conference set for October 22, according to AmmoLand. In that case, DOJ argues that statewide and nationwide relief would be improper. Those proceedings concern what courts will order; ATF's nationwide policy is a separate, voluntary decision by the agency.

Practical checklist before you buy

• Check state law first. Ban state, registration-tied state, or no state NFA law? That answer controls more than the federal guidance does. Our suppressor state guide and OBBBA suppressor article give background.
• Decide on registration deliberately. Registering keeps your options open if enforcement resumes and may matter for state-law purposes. Not registering cannot easily be reversed later.
• Expect a 4473 and background check at any dealer sale, and expect dealer policies to vary. Some dealers may continue to process Form 4s by default or decline 4473-only transfers while the rules settle.
• SBR or SBS owners: file a Form 20 before taking it across state lines, registered or not.
• Machine guns and destructive devices: nothing has changed. Do not assume otherwise.
• If you are a dealer: keep paying the special occupational tax, keep your GCA records, and document how you are handling registration and removal requests.

If your situation involves a move between states, a trust or estate, or a state whose law references federal registration, it is worth a consultation with a firearms attorney licensed in your state.
