Buying a Suppressor Without a Tax Stamp | Form 4473, SBRs and ATF’s New Rules⁠

Posted on by

Buying a suppressor without a tax stamp is now possible under ATF’s nationwide enforcement policy that took effect October 9, 2026. Individuals generally no longer need an approved Form 4 before acquiring a commercially manufactured suppressor, and ATF says an unlicensed individual no longer needs an approved Form 1 before privately making a suppressor, short-barreled rifle, short-barreled shotgun or “any other weapon.”

That does not mean silencers, SBRs and short-barreled shotguns have become completely unregulated.

The Gun Control Act still applies. Dealers still use Form 4473 and NICS. State and local restrictions remain in force. Interstate transfers and transportation still have rules. Machine guns and destructive devices remain fully subject to the National Firearms Act.

Most importantly, this is an ATF nonenforcement policy resting on a federal district-court decision, not a complete congressional repeal of the NFA. Anyone buying, making or transporting an unregistered firearm needs to understand what could happen if the policy changes.

Can You Buy a Suppressor Without a Tax Stamp?

Yes, at the federal level, ATF says it will no longer enforce the NFA’s prior-approval, registration and tax-stamp requirements for suppressors.

A dealer transferring a suppressor to an ordinary buyer should process the transaction under the Gun Control Act. That generally means:

  • Completing ATF Form 4473
  • Receiving an approved NICS background check unless an exemption applies
  • Confirming that the buyer is not prohibited from possessing firearms
  • Maintaining the dealer’s required transaction records
  • Complying with the buyer’s state and local laws

The transfer no longer requires an approved Form 4 under ATF’s current policy. The traditional $200 suppressor tax has also been reduced to zero.

That makes the process resemble an ordinary over-the-counter firearm purchase, although a suppressor remains a statutory firearm under federal law.

My earlier article on suppressor Form 4473 transfers without a Form 4⁠ examined the initial dealer guidance. The October 9 announcement is broader because ATF has now published a national policy covering transfers, possession, private making and interstate transportation.

Do You Still Need a Form 4 for a Suppressor?

ATF will continue accepting Form 4 applications voluntarily, but it no longer requires prior Form 4 approval for covered suppressor transfers under its present enforcement policy.

Voluntary registration may still interest buyers who live in states whose laws specifically depend upon federal NFA registration. It may also offer documentation if the federal government later changes its position.

That decision deserves careful thought. ATF says an owner may ask to remove an existing item from the National Firearms Registration and Transfer Record, but an item removed from the registry cannot simply be registered again later. Re-registration would generally require the attorney general to declare an amnesty.

In other words, deleting an existing registration is not a reversible protest button.

Do You Need a Form 1 to Make a Suppressor or SBR?

According to ATF’s October 9 guidance and FAQ⁠, an unlicensed individual no longer needs prior ATF approval under the NFA before privately making a suppressor, short-barreled rifle, short-barreled shotgun or qualifying “any other weapon.”

ATF will still accept voluntary Form 1 applications.

The agency’s language does not erase the rest of federal firearm law. An individual cannot manufacture firearms as a business without the necessary federal license and special occupational tax. A prohibited person cannot possess the resulting item. Interstate transfers remain restricted, and state or local law may forbid the project entirely.

The federal change is not permission to start cutting barrels or manufacturing suppressors before checking every law that applies where you live. “ATF is not enforcing this NFA provision” and “nothing can legally go wrong” are very different statements.

Can an FFL Transfer a Suppressor on Form 4473?

Yes. ATF directs FFLs to handle suppressor and AOW transactions as transfers of statutory firearms under the Gun Control Act.

That means a dealer must obtain Form 4473, conduct the required NICS check, keep the appropriate records and follow state residency restrictions.

ATF says dealers may also transfer suppressors between qualified FFLs without mandatory Form 3 approval. A Form 3 may still be submitted voluntarily.

Dealers engaged in manufacturing, importing or selling NFA firearms must continue paying the applicable special occupational tax. Congress eliminated the making and transfer taxes on covered items, but it did not eliminate those business taxes or federal licensing obligations.

What About SBR and Short-Barreled Shotgun Purchases?

Short-barreled rifles and short-barreled shotguns present an additional Gun Control Act problem.

Federal law generally prohibits an FFL from transferring an SBR or SBS without authorization from the attorney general. Historically, the approved NFA transfer supplied that authorization. The district court enjoined the NFA approval process without creating a replacement procedure under the Gun Control Act.

ATF says it is developing new forms and regulations. Until that system exists, the agency says it will exercise enforcement discretion and will not enforce the affected Gun Control Act transfer restriction.

That allows dealers to transfer covered SBRs and short-barreled shotguns under the current policy, but the legal structure is less clean than the process for suppressors. Buyers should expect dealers to proceed cautiously while ATF develops its replacement system.

Can You Travel With an Unregistered Suppressor?

ATF says it will not enforce the NFA prohibition against interstate transportation of an unregistered suppressor or other covered $0-tax item.

That does not override state law. A suppressor that is lawful in the state where a trip begins may be prohibited at the destination or in a state crossed along the way.

Short-barreled rifles and short-barreled shotguns have another requirement. ATF says individuals must continue filing Form 20 before transporting an SBR or SBS across state lines, even when the firearm is unregistered.

The practical distinction is:

  • Suppressor: No Form 20 requirement identified in ATF’s new FAQ, but every applicable state law still matters.
  • SBR or SBS: Form 20 remains required for interstate transportation.
  • Machine gun or destructive device: The complete NFA system remains applicable.

Moving, attending an out-of-state match, hunting across state lines or sending a firearm to a manufacturer for repair can all create interstate issues. Check the law before the item enters the vehicle, not while explaining the situation beside the highway.

Can You Privately Sell an Unregistered Suppressor?

ATF says an unlicensed individual may transfer a covered item without prior NFA approval under the agency’s present policy.

The Gun Control Act still prohibits an unlicensed person from transferring a firearm to someone the seller knows or reasonably believes is prohibited. An unlicensed person also generally cannot directly transfer a firearm to a resident of another state.

State laws may require dealer involvement, background checks, permits or federal registration. Some states prohibit suppressors, SBRs or short-barreled shotguns entirely. Others define lawful possession by reference to compliance with the NFA, creating uncertainty when an item is federally unregistered but tolerated under an ATF enforcement policy.

ATF expressly says it cannot promise that state authorities will consider an unregistered item lawful.

Are Machine Guns and Destructive Devices Included?

No.

Machine guns and destructive devices remain taxable NFA firearms. Their transfer, making, registration and possession requirements remain in force.

The October 9 policy applies to the categories for which Congress reduced the making and transfer taxes to zero:

  • Suppressors or silencers
  • Short-barreled rifles
  • Short-barreled shotguns
  • “Any other weapons” as defined by federal law

This does not turn a CMP M14 receiver into a transferable semiautomatic rifle. The federal government’s “once a machine gun, always a machine gun” position remains separate from the new treatment of $0-tax items. My article on the CMP M14 sale and machine-gun classification⁠ covers that issue.

What Happens if ATF Starts Enforcing the NFA Again?

This is the largest unanswered question.

ATF states that enforcement could resume if:

  • The district court’s injunction is reversed or dissolved
  • Congress imposes another tax
  • The Department of Justice rescinds the national enforcement policy
  • Other legal or factual circumstances change

The NFA treats unregistered firearms as contraband and provides felony penalties and forfeiture. ATF’s FAQ does not promise automatic grandfathering for people who acquire or manufacture unregistered items under the new policy.

It also does not promise a future registration window. The attorney general could declare a temporary amnesty, but federal law does not require one.

That is why the October 9 change is simultaneously a major victory and a calculated risk for owners who choose to remain outside the voluntary registry.

The government created this uncertainty. Congress reduced the tax to zero, a federal court rejected continued enforcement of the tax-based registration system, and ATF responded with national enforcement discretion instead of a durable statutory solution.

Private gun owners should not have needed federal permission to possess ordinary suppressors and short-barreled firearms in the first place. Nevertheless, pretending the remaining legal uncertainty does not exist would be irresponsible.

Bottom Line on Buying a Suppressor Without a Tax Stamp

Under ATF’s policy effective October 9, 2026:

  • A buyer can acquire a suppressor from a dealer using Form 4473 and NICS without mandatory Form 4 approval.
  • An unlicensed individual does not need prior Form 1 approval to make a covered item under the NFA.
  • NFA registration remains available voluntarily.
  • SBR and SBS interstate transportation still requires Form 20.
  • State and local firearm laws still apply.
  • Machine guns and destructive devices remain fully regulated under the NFA.
  • The policy could change, and ATF does not promise grandfathering or a future amnesty.

The tax stamp may be gone for covered firearms, but judgment is still required. Read the official guidance, verify the law where you live and preserve records showing when and how the item was lawfully acquired.

The Second Amendment does not contain a barrel-length chart, a suppressor waiting period or an exception allowing unelected agencies to ration ordinary arms. October 9 was a substantial step toward treating peaceful gun owners like citizens rather than applicants. Congress should finish the job by repealing the remaining federal restrictions instead of leaving Americans dependent upon enforcement discretion.
