Silencer Shop Foundation v. ATF: What the Court Ruled and What Comes Next
One federal lawsuit in San Angelo, Texas, is why you can now buy a suppressor or a short-barreled rifle on a Form 4473. Here's what the court decided, why the government didn't appeal, how ATF extended the result to everyone, and what's still open, from the court filings and ATF's own documents.
- Court: U.S. District Court for the Northern District of Texas, San Angelo Division, No. 6:25-cv-56-H, Judge James Wesley Hendrix. A related case, Jensen v. ATF, was consolidated with it.
- Filed: July 4, 2025, the day the tax cut was signed.
- Decided: August 5, 2026, with a permanent injunction for the plaintiffs.
- Appeal: none.
- Nationwide effect: since October 9, 2026, by ATF enforcement policy, not by the court order itself.
Why the case was filed
The National Firearms Act has always rested on Congress's power to tax. The One Big Beautiful Bill Act (Pub. L. 119-21) cut the making and transfer tax on suppressors, short-barreled rifles (SBRs), short-barreled shotguns (SBSs) and "any other weapons" (AOWs) to $0, effective January 1, 2026, but left the registration and approval system in place. The plaintiffs argued that a scheme built to collect a tax can't survive once the tax is zero.
The plaintiffs included Silencer Shop Foundation, SilencerCo Weapons Research, B&T USA, Palmetto State Armory, Gun Owners of America, Gun Owners Foundation, the Firearms Regulatory Accountability Coalition, an individual gun owner, and 15 states: Texas, Alaska, Georgia, Idaho, Indiana, Kansas, Louisiana, Montana, North Dakota, Oklahoma, South Carolina, South Dakota, Utah, West Virginia and Wyoming.
What the court decided
The court ruled for the plaintiffs on their claims that Congress lacked the power to keep these rules. According to the Solicitor General's letter to Congress, the court held the challenged provisions could not be sustained under the taxing power once the tax was zero, and could not be sustained under the commerce power either. The Second Amendment claims were dismissed without prejudice as abandoned, so the ruling is about Congress's powers, not the right to bear arms.
The final judgment permanently bars ATF, DOJ and their officials from enforcing the challenged provisions "as to untaxed firearms against the plaintiffs and, where applicable, the plaintiffs' agencies, political subdivisions, members, and customers—both current and future." The provisions are 26 U.S.C. 5812 (transfers), 5822 (making), 5841 (registration) and 5861(b)–(f), plus 27 C.F.R. 479.62 and 479.84. For the Jensen plaintiffs, the court also enjoined the marking rule (5842(b)) and 5861(i), but its injunction does not cover AOWs for them.
The judgment was stayed for seven days and took effect in mid-August. It did not touch machine guns, destructive devices or the special occupational tax.
Why it covered only the plaintiffs
The injunction protects the people who sued and their members and customers, not the whole country. According to analyses by attorney John Pierce and the Self Defense Fund, the court declined to issue a universal injunction, relying on the Supreme Court's 2025 decision in Trump v. CASA, which sharply limited them. For about two months, whether you could skip a Form 4 depended on whether you were a member or customer of a plaintiff.
The government chose not to appeal
On September 24, 2026, the Solicitor General wrote to House Speaker Mike Johnson under 28 U.S.C. 530D that "the Department of Justice has determined not to file an appeal." The letter was filed with the court on October 1. The government had 60 days from the judgment to appeal, and Silencer Shop reports that window closed October 5. The judgment stands, though a district court ruling doesn't bind other courts.
October 9: ATF applies it to everyone
ATF's October 9 Open Letter went further than the court: as a matter of enforcement discretion, ATF will no longer enforce approval, registration, tax-stamp and related NFA requirements for suppressors, SBRs, SBSs and AOWs for anyone. Details are on our NFA updates hub and in our guides to buying a suppressor in 2026 and SBR rules in 2026.
October 16: the fact sheet
ATF's guidance page now shows "Last Updated October 16, 2026" and links a one-page fact sheet, "NFA Guidance: Liberty and Justice for All." The sheet itself carries no readable date. It says "A citizen's rights should not depend on who could afford a lawyer or who filed a lawsuit," and that DOJ and ATF used enforcement discretion so the injunction "applies to everyone, not just those covered parties."
It changes no policy. It restates the October 9 letter and lists what did not change: prohibited persons stay prohibited, state and local laws still apply, machine guns and destructive devices keep the full NFA process and the $200 tax, NFA businesses still pay special occupational taxes, Form 4473 and NICS checks continue, and ATF keeps accepting Forms 1, 2, 3 and 4. Two lines deserve a close read:
- Form 20: "For now, transporting a short-barreled rifle or short-barreled shotgun across state lines still requires an approved Form 20."
- Dealer sales of SBRs and SBSs: "ATF is drafting regulations to address the gap in 18 U.S.C. § 922(b)(4). Until final rules are issued, ATF will not enforce that provision." ATF's October 9 FAQ already said it would not enforce 922(b)(4) until regulations exist.
What's still open
The states' motion to clarify. On September 11, 2026, nine of the plaintiff states asked the court whether the injunction covers every relevant transfer within their borders and whether ATF must identify who is covered. On October 12, DOJ answered that there's no need to decide, since ATF isn't enforcing the provisions against anyone, and that the injunction covers the states only as entities that own their own NFA firearms. As of CourtListener's docket on October 16, the court had not ruled.
A parallel case. Several of the states are also suing in Brown v. ATF, No. 4:25-cv-1162 (E.D. Mo.), seeking an injunction "throughout Plaintiff States," DOJ's response notes. DOJ argues the claims of the five states that also won in Texas are precluded. On October 15, the Missouri court moved its status conference to December 3, 2026; see our Missouri guide.
The policy itself. The nationwide part rests on DOJ's discretion. ATF's FAQ warns enforcement could resume if Congress imposes a new tax, the injunction is overturned or the guidance is rescinded.
State law. Many states reference federal registration. See our guides for Georgia, North Carolina, Michigan, Texas, plaintiff states Indiana, Oklahoma and South Carolina, and Missouri, home of Brown.
What it means if you're buying
Federally, a suppressor, SBR, SBS or AOW now takes what a handgun takes: a Form 4473 and a background check at a dealer in your state. Keep your receipt. If your state ties legality to federal registration, a $0 voluntary Form 4 or Form 1 may be the safer call. Take an SBR or SBS across state lines only with an approved Form 20. Hearing protection without a federal permission slip is a long-overdue win. Paid $200 before the change? See tax stamp refunds.
