How to Buy a Suppressor Without a Form 4 After Oct. 9, 2026

You buy a suppressor without a Form 4 the same way you buy a rifle: a Form 4473 and a NICS check at a licensed dealer in your home state, then you take it home. That has been the federal process for everyone since October 9, 2026, when ATF announced it will no longer require approval or registration for suppressors, short-barreled rifles, short-barreled shotguns, and AOWs. Our breakdown of ATF's October 9 NFA guidance covers every provision ATF stopped enforcing. The three steps below cover the buying decision.

1. Check your state's suppressor law. Federal law no longer requires a Form 4, so your state decides what else applies. Where no state or local suppressor restriction applies, the Form 4473 and NICS check are the whole transfer. In a state whose statute only allows a suppressor that is registered under or possessed in compliance with federal law, plan on a voluntary eForm 4. Suppressors remain banned for civilians in eight states.
2. Buy from a licensed dealer in your home state. Pick the suppressor, complete a Form 4473, and pass the NICS background check at a dealer licensed in your state of residence. Since October 9, 2026, ATF does not require a Form 4, fingerprints, a passport photo, CLEO notification, or an ATF approval wait for suppressors, short-barreled rifles, short-barreled shotguns, or AOWs.
3. Decide whether to file a voluntary eForm 4. ATF still accepts and approves Form 4s and keeps the National Firearms Registration and Transfer Record. File one, at a $0 tax, if your state keys on federal registration, you want trust ownership, you travel through states that restrict suppressors, or you want a registered item if federal enforcement ever resumes.

No one needs a Form 4 for a suppressor, short-barreled rifle, short-barreled shotgun, or AOW under federal enforcement policy as of October 9, 2026. ATF Director Robert Cekada signed an open letter that day stating ATF will no longer require individuals to seek approval before making or transferring those items, and will no longer require them to be registered in the National Firearms Registration and Transfer Record. The Justice Department, under Attorney General Todd Blanche, made that call as a matter of enforcement discretion so the result of Silencer Shop Foundation v. ATF would apply to everyone instead of only the parties to the case.

The court's injunction itself is still party-specific. It protects the plaintiffs, their members, and their current and future customers, which is how the first no-Form-4 suppressor transfers happened on August 13. Everyone else now relies on the department's policy, not on the judgment. The NFA remains federal law, and the reasoning behind the ruling is in our coverage of the court decision. Machine guns and destructive devices are outside all of it: they keep the $200 tax and every NFA requirement, Form 4 included.

Your state, not ATF, now decides whether a Form 4473 is the whole process. Suppressors remain legal in 42 states, and the bans in California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island are untouched by the federal change. ATF says most states require that NFA items be possessed in compliance with federal law or registered under the NFA, and that it cannot say whether an unregistered suppressor held under federal enforcement discretion qualifies as lawfully held or registered for state purposes. In those states the voluntary eForm 4 is the conservative path. Our suppressor laws by state table names the controlling statute for every state and whether it keys on registration or federal-law compliance.

Dealers carry the state-law risk at the counter. The Gun Control Act still bars a licensed dealer from transferring any firearm, suppressors included, in violation of state or local law under 18 U.S.C. 922(b)(2), and ATF tells dealers who are unsure about unregistered items to get legal advice and check with state authorities. When Silencer Shop launched no-Form-4 transfers in August, it counted 27 states free of state-level NFA requirements and kept filing Form 4s in the roughly 15 states whose statutes tie possession to federal registration. In registration-keyed states, a dealer may keep running a voluntary Form 4 so the can goes on the registry.

File a voluntary eForm 4 when the registry record is worth more to you than the shorter wait. ATF still maintains the registry and approves every NFA form submitted voluntarily, and the federal tax is $0. For applications finalized in July 2026, ATF reported average processing times of 9 days for individual eForm 4 and 33 days for trust eForm 4. Individual waits can be longer. Four situations make it the better choice: your state ties possession to federal registration or compliance, you want the suppressor owned by and registered to a trust, you travel through states that restrict suppressors, or you want a registered item if federal enforcement ever resumes.

The step-by-step dealer process is in our how to buy a suppressor guide, and choosing the right first can is the same exercise it always was: our suppressor buying guide covers hosts, mounting systems, and the current market by caliber. If you register, ATF's July 2026 fingerprint and photo proposal would cut the remaining paperwork on Form 1 and Form 4 applications.

Federally, an unregistered suppressor can cross state lines: ATF is not enforcing 26 U.S.C. 5861(j), the NFA ban on moving unregistered items in interstate commerce, and suppressors do not need a Form 20 to travel. Short-barreled rifles and shotguns are different. They still need an approved Form 20 before interstate transport under 18 U.S.C. 922(a)(4), registered or not, because that rule comes from the Gun Control Act.

The remaining travel risk is state law along the route. ATF warns it is unclear whether state courts will apply the federal transport safe harbor in 18 U.S.C. 926A to an unregistered NFA item, so driving an unregistered can through a state that bans suppressors, or only allows registered ones, carries risk even when your origin and destination allow it. SilencerCo's buyer guidance already told Form 4473 purchasers to keep those suppressors in the purchase state and pointed anyone who hunts, competes, or travels out of state to the Form 4; with the federal transport question settled, state law is why that advice still holds. A registered suppressor with its approved form in the case is the cleanest thing to carry.

Dealers can now sell short-barreled rifles and shotguns without a Form 4 as well. The Gun Control Act at 18 U.S.C. 922(b)(4) bars a dealer from selling an SBR or SBS except as specifically authorized by the Attorney General, and an approved Form 4 was the only authorization that existed. ATF says no non-NFA mechanism exists yet, it is drafting forms and regulations to create one, and it will not enforce 922(b)(4) until those regulations exist. AOWs follow the suppressor path: a 4473 and a NICS check.

Making one yourself no longer requires an approved Form 1, and ATF is not enforcing the NFA marking requirement on these items. A voluntary Form 1 still registers what you build. Possessing an NFA item with an obliterated serial number remains a federal crime, an unlicensed maker still cannot go into the business of making or selling them, and state SBR and suppressor laws apply on top of everything.

For a braced AR pistol, the conversion is a stock swap. A six-position carbine buffer tube takes a collapsible stock like the B5 Bravo, Magpul CTR, or BCM Gunfighter Mod 0. In a state that ties SBR possession to federal registration or compliance, file the voluntary Form 1 and let it clear before the stock goes on. Our AR pistol to SBR conversion guide covers the parts and measurements, and the best AR-15 stocks guide ranks the wider field.

Every Gun Control Act rule still applies, because suppressors, SBRs, SBSs, and AOWs remain statutory firearms. Dealers run a 4473 and NICS check and keep transaction records, generally sell only to residents of the state where they are licensed, and cannot transfer to a prohibited person. Unlicensed owners cannot sell these items to residents of other states. Businesses that manufacture, import, or deal in any NFA item still owe the special occupational tax, and manufacturers still serialize every firearm and silencer they make.

Existing registrations stay on the books. ATF will remove a registered item on written request to its NFA Division, but says a removed item cannot be re-registered unless the Attorney General declares an amnesty. There is no federal benefit to removal and a permanent downside if enforcement resumes, so leave registered suppressors registered.

The October 9 change is a policy, and ATF spells out how it could end: Congress imposes a new tax on these items, the Silencer Shop Foundation v. ATF injunction is dissolved or overturned, or the Justice Department rescinds the guidance. ATF also states that the NFA treats unregistered items as contraband carrying felony penalties and forfeiture, that federal law does not generally allow registering an item after the fact, and that nothing automatically grandfathers unregistered items. The Attorney General can hold a registration amnesty of up to 90 days but is not required to.

For most buyers in states without a suppressor law, the 4473 path is the practical choice and the risk is a future one. For a buyer who wants certainty that survives a change in policy, a voluntary $0-tax Form 4 is the one status that does not depend on the guidance staying in place.

Since October 9, 2026, you can buy a suppressor without a Form 4 anywhere state law allows it: a Form 4473, a NICS check, and a dealer in your home state. Check your state first, because many states still key on federal registration. File a voluntary $0-tax eForm 4 if you live in one of those states, want trust ownership, travel with the suppressor, or want protection if federal enforcement resumes.
