ATF Halts NFA Enforcement Nationwide

The ATF will no longer enforce NFA registration, making, or transfer rules against anyone, anywhere, for suppressors, SBRs, SBSs, and AOWs — not just the gun owners who sued.

We covered the legal groundwork in NFA Items in 2026: What Actually Changed, and Who It Applies To: the tax-stamp fee hit zero on January 1, and a federal judge ruled on August 5 that a $0 tax can't support the NFA's constitutional basis. That ruling only bound the plaintiffs, thanks to the Supreme Court's Trump v. CASA limits on nationwide injunctions. That's the gap that just closed.

What's new: The Department of Justice told Congress on September 24 it wouldn't appeal Silencer Shop Foundation v. ATF. The appeal window closed October 5 with nothing filed. Five days later, ATF issued an open letter and FAQ telling every FFL and every gun owner in the country it would stop enforcing NFA registration requirements for suppressors, SBRs, SBSs, and AOWs, effective immediately.

Why ATF did this instead of waiting: The agency said enforcing the ruling against only the named plaintiffs and their customers created "inequity and disuniformity" — a guy in Boise with a Form 4 pending would be treated differently than a Silencer Shop Foundation member standing next to him at the counter. ATF's fix is enforcement discretion, not a change in law. The NFA itself is still on the books.

What's actually not enforced now:

• No prior approval needed to make or transfer a suppressor, SBR, SBS, or AOW
• No registration required in the NFA registry, and ATF won't prosecute possession of an unregistered one
• No enforcement of the NFA marking rule or the interstate-transport ban on unregistered suppressors and AOWs

Yes, but: This is narrower than it sounds. Machine guns and destructive devices are untouched — still taxed, still fully regulated. Illegally imported NFA items and ones with obliterated serial numbers are still federal crimes. Anyone in the business of making or dealing these items still owes the special occupational tax, and the Gun Control Act's paperwork hasn't gone anywhere: a dealer still runs a Form 4473 and a NICS check on any unlicensed buyer.

The SBR exception inside the exception: Short-barreled rifles and shotguns carry an extra GCA restriction, 18 U.S.C. § 922(b)(4), barring a dealer from selling one without specific ATF authorization — historically, an approved Form 4. Judge Hendrix never touched that provision, and ATF admits no replacement approval process exists yet. For now, the Bureau says it won't enforce § 922(b)(4) either, while it writes new forms and regulations. Crossing state lines with an SBR still requires a Form 20 under separate GCA authority ATF is still actively enforcing — that one didn't get the pass.

Registration isn't gone, it's optional. ATF will still process Forms 1 through 4 for anyone who wants their item on the books, and dealers can still file a Form 3 voluntarily on interstate transfers. Pulling an item off the registry means emailing the NFA Division directly — and ATF warns that once it's off, it's off, barring a future amnesty declared by the Attorney General.

State law is the live wire ATF won't touch. Most states tie their own suppressor and SBR rules to federal registration or federal legality. ATF explicitly declined to say whether an item held under this policy counts as "lawfully possessed" for those state statutes. A handful of states ban these items outright regardless of what ATF does, and a dealer who transfers into one of those states still faces federal penalties for violating state law under the GCA.

What to watch: Judge Hendrix gave DOJ until October 12 to respond to a motion from plaintiff states asking whether the injunction reaches them more broadly. That answer could reshape how states that already allow suppressors handle this going forward. Buyers in restrictive states should assume nothing has changed locally until their state says otherwise.

The bottom line: federal enforcement has effectively stood down on NFA paperwork for suppressors, SBRs, SBSs, and AOWs, but the GCA's background-check and interstate rules are still fully alive, and state law can still land you in trouble even where federal law won't.
