ATF's NFA pause: what the FAQ says about marking, serial numbers and reversal

ATF's Oct. 9, 2026, decision to stop enforcing National Firearms Act registration for suppressors and short-barreled guns also covers the NFA's marking requirement. But the law itself has not changed, licensed manufacturers must still serialize, and the ban on obliterated serial numbers is still enforced, according to ATF's FAQ on atf.gov. Grok SI News first reported the policy on Oct. 12, and on Oct. 15 reported how states are reading it. This update focuses on details in that FAQ.

Note on sources: quotations from ATF's Oct. 9 open letter come from a copy posted by the American Suppressor Association, not from atf.gov directly.

The background: Silencer Shop Foundation v. ATF

The policy grew out of Silencer Shop Foundation v. ATF, No. 6:25-cv-00056-H, in the U.S. District Court for the Northern District of Texas, Lubbock Division. The case is consolidated with Jensen v. ATF. In an Aug. 5, 2026, opinion, Judge James Wesley Hendrix ruled for the plaintiffs. According to ATF's open letter, the 2025 law known as the One Big Beautiful Bill Act (Pub. L. 119-21) set the making and transfer tax on these items at $0. The court held that the registration and transfer provisions were no longer a valid exercise of Congress's taxing power for them, and that the commerce power could not save them, according to the letter and ATF's FAQ.

That injunction, effective Aug. 12, protected only the plaintiffs, their members and customers. DOJ said in early October it would not appeal; GIFFORDS responded on Oct. 2. ATF's Oct. 9 letter extended non-enforcement to everyone: "These policies apply uniformly to anyone otherwise subject to these requirements, not just to the plaintiffs".

What changed

ATF's FAQ on atf.gov lists the NFA provisions the agency will not enforce for short-barreled rifles (SBRs), short-barreled shotguns (SBSs), suppressors and "any other weapons" (AOWs):

• prior approval to make or transfer these items;
• registration in the National Firearms Registration and Transfer Record;
• the ban on transporting unregistered NFA items across state lines (26 U.S.C. § 5861(j));
• "The NFA requirement to mark all NFA firearms."

Individuals "no longer need to file a Form 1 and receive ATF approval before making or transferring such items," the atf.gov FAQ says. ATF also says it will not enforce the Gun Control Act's 18 U.S.C. § 922(b)(4), which governs dealer sales of SBRs and SBSs, "until such regulations exist".

What did not change

• The law. ATF calls the policy "enforcement discretion". The NFA's marking requirement is unenforced, not repealed.
• Serial numbers. Licensed manufacturers "must serialize all firearms and silencers," according to the atf.gov FAQ. ATF continues to enforce § 5861(h), which bars NFA firearms with obliterated serial numbers, and § 5861(k), on illegal imports. The FAQ does not expressly say individuals may leave a homemade suppressor unmarked.
• Scope. Machine guns and destructive devices "remain taxable items and subject to all NFA provisions".
• The Gun Control Act. "All GCA requirements still apply," including Form 4473 and a NICS background check at licensed dealers. Unlicensed makers "may not engage in the business" and may not transfer to residents of other states or to prohibited persons. A Form 20 is still required before taking an SBR or SBS across state lines.
• State law. ATF says its policy "does not affect these state laws".
• Leaving the registry. ATF's atf.gov FAQ says items can be removed from the registry but not re-registered without an amnesty: "once an item is removed, it cannot be re-registered unless the Attorney General declares an amnesty".

'Common use' and a future reversal

One question is whether widespread unregistered ownership would make a reversal harder, since the Supreme Court has said the Second Amendment protects arms "in common use" for lawful purposes. Such an argument would matter only as a defense raised in court after enforcement resumed; it would not stop a future administration from rescinding the policy. According to ATF's FAQ, enforcement could resume if Congress imposes a tax, if the injunction is dissolved or overturned, or if DOJ simply rescinds the policy. The atf.gov FAQ warns that "the NFA treats unregistered firearms as contraband" with "felony penalties," and that federal law has no "provisions that would automatically grandfather" them. No court has ruled on whether suppressors or SBRs are in common use in this context.

Reaction

Adam Kraut, executive director of the Second Amendment Foundation, said on Oct. 9 that "by its very nature purely as 'guidance' it cannot, and does not, provide a permanent fix". Emma Brown, executive director of GIFFORDS, said on Oct. 2, responding to DOJ's decision not to appeal: "This decision is a failure to defend public safety".
