You’ve heard the term. Maybe you’ve seen one at a range or in a hunting video. And you’ve probably wondered: are those legal? Can I actually own one? How does the process work?
The short answers: Yes, in 42 states. Yes, you can. And the process is simpler than you think — especially since January 1, 2026, when the federal government eliminated the $200 tax stamp entirely.
This page is your starting point. Read it in order, or jump to whatever question you have right now.
The 5 Questions Every New Buyer Has
1. Are suppressors actually legal?
Yes — in 42 states. Suppressors are federally legal and regulated under the National Firearms Act (NFA) of 1934. Eight states prohibit civilian ownership: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island.
If you’re not in one of those eight states, you’re in the clear at the state level. Federal law applies everywhere, and the federal process is the same regardless of which of the 42 legal states you live in.

2. Is the process complicated?
Not anymore. Here’s what it actually takes:
- Find a suppressor you want (we can help with that)
- Complete an ATF eForm 4 online — your dealer handles most of it
- Submit fingerprints and a photo electronically
- Pass an FBI background check (same as buying any firearm)
- Wait for ATF approval — currently processing in days to weeks for eForm submissions
- Take possession of your suppressor
That’s it. The days of year-long waits are behind us. Since the ATF moved to electronic form processing, approvals have dropped from months to days for most clean applications. The $200 tax was eliminated on January 1, 2026, so your only cost is the suppressor itself.

3. What does a suppressor actually do?
It reduces the sound of a gunshot — not eliminates it. A suppressor works like a car muffler: it slows and cools the expanding gas that exits the barrel when a round fires, reducing the peak noise level by 20 to 35 decibels depending on the caliber, ammunition, and suppressor design.
An unsuppressed centerfire rifle fires at roughly 165–175 dB. With a quality suppressor, that drops to approximately 130–145 dB — still audible, often still loud enough to damage hearing without additional ear protection on larger calibers, but a dramatic reduction that changes how shooting feels and affects everyone around you.
A suppressed .22 LR can get down to 110–120 dB — roughly the level of a jackhammer. The movies lied to you. These are not whisper devices. They are effective, practical hearing protection tools.

4. How much does a suppressor cost?
Entry-level suppressors start around $300–$400. Quality mid-range options run $500–$800. Premium cans from brands like Dead Air, SilencerCo, and Silencer Central’s Banish line range from $800 to $1,500.
As of January 1, 2026, the $200 federal tax stamp no longer applies. You pay for the suppressor, the dealer’s transfer fee (usually $25–$75), and that’s it. No more $200 on top of the purchase price.

5. Which suppressor should I get?
It depends on what you’re shooting. The right suppressor for a .308 hunting rifle is different from the right one for a 9mm pistol, which is different from a .22 LR target gun. Before you buy anything, know your primary firearm and caliber.

Key Concepts to Understand Before You Buy
Individual vs. NFA Trust
You can buy a suppressor as an individual or through an NFA gun trust. Both work. An individual purchase is simpler. A trust lets multiple people legally possess and use the suppressor — useful if you’re married, have adult children, or want to share with a range partner. Silencer Central includes a free NFA gun trust with every purchase.

Direct Thread vs. Quick-Detach
Suppressors attach to your barrel one of two ways: direct thread (screws directly onto barrel threads) or quick-detach (uses a proprietary mount for fast attachment/removal). Direct thread is simpler and lighter. Quick-detach is faster and better if you run the same suppressor on multiple hosts.
Hearing Safe vs. Not Hearing Safe
The industry standard for “hearing safe” is below 140 dB — the threshold above which permanent hearing damage can occur. Many suppressors with subsonic ammo on rimfire calibers reach this threshold. Most centerfire rifle calibers with supersonic ammunition do not, even suppressed. Always check the data. Don’t assume.
