Updated 9 October 2026. This guide previously described the ATF Form 4, fingerprints, a photograph and a long approval wait. That process no longer applies to suppressors, short-barreled rifles, short-barreled shotguns or AOWs. On 9 October 2026 the ATF announced it will no longer enforce the National Firearms Act approval and registration requirements for those four categories. Everything below is current as of that date.
Suppressors are legal to own in most states, and as of 9 October 2026 buying one works much the way buying a rifle does. The federal application, the fingerprints and the long wait for approval are gone. What remains is a Form 4473, a background check, and your own state law.
Here is how the process actually works, what a suppressor does and does not do, and what to check before you order.
This article is general information, not legal advice. NFA rules and state law change, and the details of your purchase are handled by the dealer processing it. Confirm current requirements with the ATF and with us before you commit.
What counts as an NFA item
The National Firearms Act regulates a specific set of items beyond ordinary rifles, shotguns, and handguns. The ones most buyers encounter:
- Suppressors (also called silencers in the law) — by far the most common NFA purchase
- Short-barreled rifles (SBR) — rifles below the statutory barrel or overall length
- Short-barreled shotguns (SBS)
- Any Other Weapons (AOW) — a catch-all category for certain concealable and unconventional firearms
- Machine guns and destructive devices — these still carry the $200 transfer tax
Machine guns and destructive devices still require federal registration and an approved $200 tax stamp. Suppressors, SBRs, SBSs and AOWs no longer do. All of them remain subject to state law on top of federal law: several states prohibit some or all NFA items outright, and that is the first thing to check.
What a suppressor actually does
It reduces muzzle blast. It does not make a firearm quiet in the way films suggest.
A centerfire rifle with a suppressor is still loud — often still loud enough to warrant hearing protection. What changes is meaningful: the sound drops enough to protect hearing in many cases, muzzle blast and flash are dramatically reduced, recoil is softened, and you can hear range commands, a spotter, or an animal moving. On a hunt, the reduction in blast is often more valuable than the decibel figure.
Subsonic ammunition is what produces the genuinely quiet result, because a supersonic bullet makes its own crack regardless of what is on the muzzle.
The buying process, step by step
- Confirm it is legal where you live. State law governs, it did not change on 9 October, and some states prohibit suppressors entirely. Check before you spend anything.
- Choose your suppressor and pay for it.
- Complete a Form 4473 and pass a NICS background check, exactly as you would for a rifle.
- Take it home. There is no application to file, no fingerprints, no photograph, no stamp and no wait.
What did not change. This is an enforcement decision, not a repeal of the law. The statute still stands, and the ATF was explicit that it still treats unregistered NFA items as contraband; it has simply chosen not to enforce the registration requirements for these four categories. Every Gun Control Act rule still applies: the Form 4473, the background check, our records, and the rule that we cannot transfer to anyone we know or have reason to believe is prohibited from possessing a firearm. Machine guns and destructive devices are completely unaffected.
Registration is still available, and you may still want it
The ATF has said it will keep maintaining the registry and will approve applications from anyone who chooses to file. There are two honest reasons to consider it.
This is a policy, not a repeal. Congress removed the tax on these items and the executive branch has chosen not to enforce the registration requirements. A future administration, a different court, or an act of Congress could change that posture.
There is no promised grandfather clause. The ATF addressed this directly and did not soften it: federal law does not generally allow after-the-fact registration, and while the Attorney General may declare an amnesty period, nothing requires one.
That is not a prediction. It is the reason a cautious buyer might prefer a stamp they do not currently need, and we will not talk anyone out of that choice.
How we handle it
We transfer suppressors, SBRs, SBSs and AOWs on a Form 4473 and a NICS check, the same as any other firearm. If you would prefer to register yours anyway, tell us and we will run it through the traditional process instead.
If you are not sure which is right for you, call. We would rather spend ten minutes on the phone than have you make a decision like this from a web page.
Individual or trust
This mattered because an NFA item was registered to a person or to an entity, and only that person or entity could lawfully possess it. With registration no longer required for suppressors, SBRs, SBSs and AOWs, that constraint does not apply to an unregistered item. It still matters in two cases: if you choose to register voluntarily, and for machine guns and destructive devices, which are unchanged.
- Individual — simpler and cheaper. Only you may possess the item. If someone else has it without you present, that is a problem.
- Trust — costs more to set up, and every responsible person on the trust submits their own fingerprints and photo. In exchange, anyone named on the trust may legally possess the item, and it can pass to heirs without a fresh transfer.
If you want your spouse or hunting partner to be able to use it, or you intend to build a collection, a trust is usually worth the setup cost. If it is one suppressor for your own use, individual registration is simpler. A lawyer who does this routinely is the right person to draft a trust — a generic template is a false economy on something this consequential.
Choosing the suppressor itself
Caliber and rating
A suppressor must be rated for the cartridge and barrel length you will use it on. A .30 caliber can generally run smaller calibers, which makes it the versatile choice if you want one can across several rifles — at the cost of slightly less suppression on the smaller rounds than a dedicated unit would give.
Check barrel-length ratings carefully. Short barrels raise gas pressure and heat, and not every suppressor is rated for a short-barreled host.
Mounting
Direct thread is simplest and lightest. Quick-detach systems mount over a muzzle device and let you move the suppressor between rifles quickly, at some cost in weight, length, and price.
Your host rifle needs a threaded barrel in the correct thread pitch. Confirm this before buying — a barrel that is not threaded means either a new barrel or gunsmithing.
Materials and weight
Titanium is light and excellent for hunting; stainless and Inconel are heavier and handle sustained fire better. A hunting rifle you carry all day and shoot twice wants light. A rifle you shoot in volume wants durable.
Remember that a suppressor changes the balance of the rifle and usually shifts point of impact — re-zero with the can attached, and know your offset if you shoot both ways.
Living with one
- If you registered yours, keep the stamp accessible. A copy with the item is standard practice. If you did not register it, there is nothing to carry.
- They get extremely hot. Hot enough to burn you and to damage anything mounted against them. A suppressor cover helps with handling and mirage.
- They increase fouling. A suppressed semi-auto runs dirtier and gassier, see our cleaning guide.
- Moving an SBR or SBS across state lines still needs ATF approval on a Form 20, whether or not the item is registered. That requirement was not affected.
- Hunting regulations vary. Suppressor use for hunting is allowed in many states but not all, and sometimes varies by species.
Common questions
Are suppressors legal?
Federally legal to own in most states. As of 9 October 2026 no federal registration or tax stamp is required for a suppressor. Some states prohibit them outright, and state law did not change. Check your state before ordering.
Do I need my own FFL?
No. You need a dealer licensed to handle NFA items to process the transfer, which is what we do.
Do I still have to pay $200 for a tax stamp?
No. The $200 transfer tax on suppressors, SBRs, SBSs and AOWs was eliminated on 1 January 2026, and since 9 October 2026 there is no stamp and no registration requirement for them either. Machine guns and destructive devices still carry the $200 tax and the full NFA process.
Can I let a friend shoot it?
If your suppressor is unregistered under the current guidance, the NFA possession rules that used to tie an item to one registered owner do not apply to it. If you chose to register yours to yourself, the old rule still governs that item: another person may use it while you are present and in control, and possession without you is a serious offense. A trust is the way to give other named people independent possession of a registered item.
Can it be returned if I change my mind?
No. NFA items are final sale — see our returns policy. This is a purchase to be certain about before you file, which is why it is worth a conversation first.
Where to start
Confirm your state allows it, check that your intended host has a threaded barrel in the right pitch, and pick a suppressor rated for your cartridge and barrel length. Then talk to us before you buy. The federal process is far simpler than it was, but the choice of can is still not one you can undo.
