Education · The NFA, without the noise

Everything you need to own a suppressor — explained plainly.

What a suppressor actually does, where it's legal, what the paperwork really involves, and how a purchase moves from cart to your hands. No hype, no Hollywood.

How it works

It doesn't silence. It manages pressure.

When a round fires, a column of gas leaves the muzzle at enormous pressure and temperature. That sudden expansion into open air is the blast you hear. A suppressor gives that gas somewhere to go first — a series of chambers and baffles where it can spread out, slow down, and cool before it ever reaches the air.

Lower the pressure spike, lower the noise. A good suppressor takes 20–35 dB off the muzzle blast. What it can't touch is the sonic crack of a supersonic bullet — that's why subsonic ammunition sounds dramatically quieter through the same can.

Decibels are logarithmic. Dropping ~30 dB isn't a third quieter — it's the difference between sound that damages hearing instantly and sound you can stand next to.

How quiet is your setup?

Pick a host, a suppressor, and your ammunition. The meter shows where the shot lands against the 140 dB line where hearing damage begins — and why subsonic ammo is the real unlock.

Signal vs. noise

What people get wrong.

Suppressors make a gun silent.
They reduce the muzzle blast, usually by 20–35 dB. A suppressed centerfire rifle is still as loud as a jackhammer — quieter, not quiet.
They're only useful to criminals.
They're hearing protection. ATF data consistently shows suppressors turn up in a vanishingly small share of crime; the buyers are hunters, competitors, and range shooters protecting their ears.
Owning one is a legal gray area.
It's explicitly legal for civilians in 42 states under federal law. The process is documented, federal, and routine — you file a form and wait for approval.
You can buy one and walk out the same day.
No. Every suppressor is an NFA item. It transfers on an approved ATF Form 4 with a background check — the can stays with the dealer until your stamp clears.
The Hollywood 'pfft' is real.
That sound is a movie invention. A suppressed gunshot is a sharp, flat report — closer to a heavy door slamming than a whisper.
What changed in 2026

The $200 barrier is gone. The paperwork isn't.

The One Big Beautiful Bill Act cut the federal transfer tax on suppressors from $200 to $0, effective January 1, 2026. For nearly a century that stamp was the single biggest hurdle to ownership. It's now zero.

What didn't change: suppressors are still NFA items. The registration, the Form 4, the background check, and the wait for approval all remain. The cost came down — the process stayed.

The process

How you actually buy one.

Five steps, start to finish. The same path whether you buy from us or anywhere else.

01
Choose the can
Pick a suppressor from a licensed SOT dealer. Caliber rating, length, and weight matter more than brand — match it to the host firearm.
02
Name your dealer
Choose the local FFL/SOT dealer who will receive it and hand it to you. This is where you'll pick it up once approved.
03
File the Form 4
Application for transfer: fingerprints, a passport photo, and your info, as an individual or through an NFA trust. The tax is now $0.
04
Background check
The ATF runs the check and approves the transfer. eForm filings have pulled this down to days or weeks, not the year it once took.
05
Approved — collect
Your stamp clears. You complete a 4473 with the receiving dealer, like any firearm, and walk out with it.
On Piece & Quiet

Where we fit in.

We connect you to licensed dealers; your payment runs through our partner GunTab, which holds the funds until the transfer clears. Piece & Quiet never takes possession of the suppressor or the money — every item moves dealer-to-dealer and transfers to you on your own Form 4.

How a private sale works

Selling a suppressor you own works one of two ways, depending entirely on where your buyer lives. Each path runs start to finish below.

You hold the suppressor the entire time.
1
Buyer purchases
The price locks and the buyer's payment is held by our partner GunTab until the transfer completes. Nothing ships.
2
File the Form 4 together
You and the buyer complete one Form 4 and submit it to the ATF. The buyer adds fingerprints, a photo, and notifies their local law enforcement. The stamp is $0.
3
You keep the suppressor
It stays in your possession the whole wait. Never hand it over before approval.
4
ATF reviews
The application sits in the queue, typically a few months on eForms.
5
Approved — transfer in person
You hand it over, the buyer takes possession, and GunTab releases your payment.

Where you live

Legal in 42 states. Not in these.

Federal law sets the floor; your state has the final say on possession. Civilian suppressor ownership is prohibited in eight states and the District of Columbia. A couple of states allow ownership but restrict hunting with one — always confirm your local statute.

We enforce this at checkout. Listings can't ship to a receiving dealer in a restricted state — the marketplace blocks it before you can pay.

The vocabulary

Terms worth knowing.

NFA

FFL
Federal Firearms License. The license a dealer holds to deal in firearms.
SOT
Special Occupational Taxpayer. An FFL who has paid the tax to deal in NFA items like suppressors.

The ATF application to transfer an NFA item to you. Requires fingerprints, a photo, and a background check.
Form 3
The tax-free ATF transfer between two licensed dealers — how your can reaches your local dealer.
Tax stamp
Proof the transfer tax was paid. As of January 2026 the amount is $0, but the stamp still issues on approval.
Baffle
The internal cones that give expanding gas room to slow and cool, dropping the muzzle blast.
Subsonic
Ammunition that stays below the speed of sound, so there's no sonic crack for the suppressor to fight.
NFA trust
A legal trust that owns the suppressor, letting more than one person possess it and easing estate transfer.
