I prefer that the NFA should go away but this lines out the pluses & minues of the current situation...
Since the August 2026 injunction, some buyers can get a suppressor on a 4473 alone. What you give up vs. a Form 4, which states allow it, and our recommendation.

4473 vs. Form 4 Suppressors
For most buyers, the short-term gain of a 4473 suppressor doesn't outweigh the long-term benefits of a Form 4.
Was the NFA repealed? No.
The National Firearms Act is still on the books. Here's what each one did.
What ATF did. The Justice Department describes it as using its "enforcement discretion" (
ATF open letter). ATF also says it "will not enforce § 5861(j) as applied to unregistered NFA items." That's the section that makes it a crime to move an unregistered NFA firearm across state lines (
ATF guidance).
What didn't change.
- Neither one repealed the NFA. The registration requirement is still federal law. ATF has chosen not to enforce it, and that choice can be reversed.
- A court order and an ATF policy aren't law. Neither one changed the NFA. You're relying on the current ATF and administration's policy, and that can change (details below).
- The felony is still on the books. A suppressor bought on a 4473 without a Form 4 isn't registered. ATF's own FAQ says people who make, possess, transfer, or receive unregistered NFA firearms "are subject to felony penalties and forfeitures" (ATF FAQ). ATF isn't enforcing that today. If a future administration rescinds the guidelines, enforcement can resume.
All of this can change
ATF says it plainly: "Material changes in legal or factual circumstances could cause NFA enforcement to resume." It lists three ways that could happen: Congress could impose a new tax on NFA firearms, the August 5 injunction could be dissolved or overturned, or the Justice Department could rescind its enforcement guidelines (
ATF guidance).
Rescinding the guidelines doesn't take a vote in Congress or a court ruling. A new administration, attorney general, or ATF director could decide to enforce the law again.
A new tax takes one act of Congress, at any amount. Congress cut the suppressor tax to $0, effective January 1, 2026, and the bill passed the House by four votes, 218 to 214.
It took a simple majority to cut the tax, and a simple majority can put one back. A change in control of the House could be all it takes.
If enforcement resumes, a registered suppressor is already compliant. A 4473 suppressor is still an unregistered NFA firearm. ATF says federal law "does not generally permit subsequent registration of unregistered NFA items." The NFA lets the Attorney General hold an amnesty of up to 90 days, but ATF adds that the Attorney General "is not required, however, to hold an amnesty or to provide forbearance" (
ATF guidance). The last NFA amnesty, in 1968, ran 30 days (
NFA Handbook § 3.2.1).
Do you want to own a suppressor or contraband?
ATF's own words are worth reading. "The NFA treats unregistered firearms as contraband," and people who possess them "are subject to felony penalties and forfeitures" (
ATF FAQ). A suppressor transferred to you on a 4473 without a Form 4 is not registered to you in the NFRTR.
What you give up with a 4473 suppressor
A 4473 suppressor comes with an asterisk built in. Some of those limits can turn it into a disposable suppressor: one you may not be able to fix, sell, move, or pass on.
The federal transfer tax on suppressors is $0. You register once, there's nothing to renew, and with a federal tax stamp the suppressor is yours for life.
Crossing state lines depends on today's policy
A registered suppressor doesn't need ATF approval to cross state lines. You still follow the laws of every state you enter. A 4473 suppressor isn't registered to you. Federal law makes it a crime to transport, deliver, or receive an unregistered NFA firearm in interstate commerce (
26 U.S.C. § 5861(j)). ATF now says it "will not enforce § 5861(j) as applied to unregistered NFA items" (
ATF guidance). That's a policy, not a change in the law. If ATF starts enforcing it again, taking a 4473 suppressor across a state line could be a federal crime.
State laws still apply. ATF says "individuals should exercise caution before transporting unregistered NFA items through states" and should check state and local law first (
ATF open letter). That matters most in the 15 states that allow suppressors only with NFA compliance, listed below.
That covers out-of-state hunts, matches, and moving. If you relocate, you also take on your new state's law, and some states tie suppressor possession to federal registration.
Do you want to be the test case?
Plenty of laws are written around a registered suppressor. If a game warden or prosecutor reads "registered" literally, a 4473 suppressor could leave you arguing in court that a federal policy satisfies state law. You might win, but you'd still have to make that argument and pay for it. With a 4473 suppressor, there's no registration to show. If an officer in another state, an insurer, or your executor asks, your answer is ATF's current enforcement policy, and that can change.
There's no "register it later"
If you buy on a 4473 and change your mind later,
there is no established path to register it. ATF says federal law "does not generally permit subsequent registration of unregistered NFA items" (
ATF guidance).
ATF's NFA Handbook also says ATF won't approve a transfer unless the firearm is registered to the person transferring it.
Passing it on has no clear path
A registered suppressor passes to an heir on a tax-exempt Form 5.
ATF's new guidance doesn't address inheritance.
ATF's NFA Handbook treats an NFA firearm that wasn't registered to the person who died as contraband that can't go through the normal estate process. If enforcement has resumed by the time your estate is settled, that's the rule your heirs could face. There's still no established way to pass a 4473 suppressor on to future generations.
The NFA registry isn't what most people picture
Nobody likes being on a federal list. The registry isn't what many people assume it is.
The NFRTR sits in the tax code, not in a gun registry the way most people imagine one. NFA forms are treated as tax returns, and registration information as tax return information. Under 26 U.S.C. § 6103, ATF is generally prohibited from disclosing it. ATF won't even confirm your registration status over the phone.
And federal law limits how your registration can be used. Information from your NFA application or registration can't be used as evidence against you in a criminal case for a violation that happened before or when you filed, unless you filed false information.
The bottom line
Today, ATF has chosen not to enforce those provisions. That's an enforcement policy, not a change in the law, and ATF says the policy could end. If enforcement resumes without a grandfathering provision, amnesty, or other relief, you could be left possessing an NFA firearm that isn't registered to you, with no established way to register it after the fact. ATF says federal law does not generally permit subsequent registration and does not automatically grandfather unregistered NFA firearms. A violation of the NFA can carry up to 10 years in federal prison (
26 U.S.C. § 5871). Would anyone actually be charged if the policy changes? No one can promise you either way.
There is also no clear answer on how a return to enforcement would happen. ATF's guidance doesn't say what notice, transition period, or relief owners would receive if the policy is rescinded.
Depending on what changes, you may also lose the ability to take it out of state, get it repaired, sell it through an established process, or reliably leave it to your family. A registered suppressor doesn't depend on ATF continuing this policy. That's why we recommend a Form 4 for most buyers.
If you already own a registered suppressor, you're on the registry either way. Skipping it on the next one doesn't take you off. It just leaves you with one suppressor that plays by different rules than the rest. And don't unregister the ones you have. ATF says once an item is removed, "it cannot be re-registered unless the Attorney General declares an amnesty" (
ATF guidance).
