Suppressor Laws by State After ATF's NFA Change (2026)

It depends entirely on your state's own statute. ATF stopped enforcing NFA approval and registration for suppressors, short-barreled rifles, short-barreled shotguns, and AOWs on October 9, 2026, but it did not and cannot change state law. In 20 states, no state law ties suppressor possession to federal registration, so a suppressor bought on a Form 4473 with no Form 4 is legal there. In 19 more, the state only allows a suppressor that is registered under the NFA or possessed in compliance with federal law, and an unregistered can is a state-law risk. Suppressors are banned outright in 9 jurisdictions.

The tables below classify all 50 states and DC by how their law ties to federal registration, with the controlling statute linked to its text. The sorting question is simple: does your state's statute mention federal registration or federal-law compliance? If it does, file the voluntary paperwork. If it does not, the 4473 is enough at the state level. For what ATF actually changed, see our breakdown of the October 9 NFA guidance.

No state tie (20 states for suppressors): buy from a dealer in your home state on a Form 4473 and NICS check, and you are done. A voluntary eForm 4 is optional insurance against a future federal reversal.

Registration required (8 states for suppressors): the statute makes NFA registration the condition for lawful possession or the only defense to a felony. File the voluntary eForm 4 to buy, or a Form 1 to make, and take possession only after ATF approves it. Alaska, Colorado, Georgia, Louisiana, Montana, Ohio, Oregon, and Wisconsin are in this group.

Federal compliance required (11 states for suppressors): the statute allows a suppressor possessed in compliance with, or not in violation of, federal law. The NFA's registration requirement is still written into federal law even though ATF no longer enforces it, and no state in this group has said an unregistered suppressor qualifies, so treat these states exactly like the registration group and file. Arizona, Connecticut, Iowa, Michigan, Minnesota, Mississippi, Missouri, Nevada, North Carolina, North Dakota, and Pennsylvania are in this group.

Registration required to use (Oklahoma and Washington): possession is lawful, but using the suppressor requires it to be registered under federal law. Washington's rule covers any use; Oklahoma's covers hunting. Register it before you shoot with it.

Restricted (Vermont): ownership has no registration tie, but a separate state rule limits where or how the suppressor can be used. Follow that rule; the federal change does not touch it.

Banned (California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island, and DC): nothing changes. These laws prohibit civilian possession whether or not the suppressor is federally registered, and a dealer may not transfer a firearm in violation of state law under 18 U.S.C. 922(b)(2).

Our guide to buying a suppressor without a Form 4 covers the dealer counter, trusts, and the voluntary eForm 4 in detail, and the how to buy a suppressor guide walks through the purchase from choosing a dealer to taking possession.

Buy the can that matches the host you shoot most. For a 5.56 AR, the Otter Creek Labs Polonium is the value pick and the SureFire SOCOM556-MINI4 is the best overall. The Dead Air Nomad 30 covers 5.56 through .300 Win Mag on one can, the Q Trash Panda is a compact titanium .300 Blackout can that mounts on Q's Cherry Bomb, the Rugged Obsidian 9 runs on a 9mm pistol with its included 1/2x28 piston, and the SilencerCo Sparrow 22 is the easiest first can for rimfire. The suppressor buying guide covers caliber, mounting, and which can to buy first.

A state law that allows a suppressor possessed "in compliance with federal law" sounds like it follows ATF wherever ATF goes. It does not. The NFA still makes possessing an unregistered suppressor or SBR unlawful under 26 U.S.C. 5861(d); the Justice Department has only decided not to prosecute it. Choosing not to enforce a statute is not the same as complying with it, and ATF's own letter says it cannot opine on whether an unregistered item held under its enforcement discretion counts as lawfully held for state purposes.

Two attorneys general have spoken since the August ruling. Montana's told prosecutors on August 27, 2026 that possessing an unregistered silencer remains a felony under Montana law and that hunting suppressors must be ATF-registered. Georgia's wrote on October 2, 2026 that his office reads Georgia's registration exception to cover people protected by the Silencer Shop injunction, and said that reading does not bind the state's 50 district attorneys. As of October 9, 2026, no state had said that an item left unregistered under ATF's nationwide policy satisfies a registration or compliance requirement, so how these states will treat one is genuinely unsettled. The voluntary eForm 4 is the only way to be certain, and it costs nothing in tax.

The state that matters is every state you pass through, not just the one you live in. 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 an unregistered suppressor driven through a registration-keyed state carries that state's risk. A suppressor needs no Form 20 to travel. An SBR does, registered or not.

ATF's change is enforcement discretion, not repeal. ATF says enforcement could resume if Congress imposes a new tax, the Silencer Shop Foundation v. ATF injunction is dissolved or overturned, or the department rescinds its guidance, and unregistered items would then be contraband with no automatic grandfathering. A registered suppressor or SBR stays federally lawful under every one of those outcomes and satisfies every state registration or compliance condition; state hunting, use, and configuration rules still apply on top. Since January 1, 2026 the federal making and transfer tax on both is $0, so registering costs the ATF wait plus any dealer, fingerprint, or photo fees.
