Buying a suppressor legally requires filing ATF Form 4, submitting fingerprints and photos, paying a tax stamp fee (currently $200, dropping to $0 on January 1, 2026), and waiting 3-12 months for approval. Suppressors are legal in 42 states. You'll purchase through a licensed dealer who handles the paperwork and holds the suppressor until your approval arrives.
So you're thinking about buying a suppressor. The NFA process sounds intimidating—forms, fingerprints, tax stamps, months of waiting. But here's the truth: it's just paperwork and patience. Once you understand the seven steps, it's straightforward.
Are Suppressors Legal?
Yes, federally. Suppressors are legal to own under the National Firearms Act. You need ATF approval, but no special license. Just one-time paperwork.
The catch? State laws. Suppressors are legal in 42 states. Eight states prohibit them:
- California
- Delaware
- Hawaii
- Illinois
- Massachusetts
- New Jersey
- New York
- Rhode Island
If you're in one of those eight, you're out of luck. For everyone else, check your state's hunting regulations—some states restrict where you can use suppressors even if ownership is legal.
The 7-Step Purchase Process
Choose Your Suppressor
Pick based on caliber compatibility. A .22 LR suppressor won't handle .308 pressures. Multi-caliber options exist—like a .30 cal can that works on 5.56, .308, and .300 BLK—but they're bigger and heavier.
Price range: Budget options start around $300-$400. Mid-tier runs $600-$900. Premium cans hit $1,200-$1,500+.
Mounting: Direct thread screws onto your barrel. Quick-detach (QD) systems let you swap between firearms fast but cost more.
Find a Licensed Dealer
You can't ship a suppressor to your house. You need a Class 3 SOT dealer—an FFL licensed to sell NFA items.
Buy local or order online and transfer through a local dealer (transfer fees vary by dealer). The dealer holds your suppressor until ATF approval comes through.
Complete ATF Form 4
This is your application to transfer the suppressor from the dealer to you. Your dealer helps with this—experienced dealers walk first-timers through it.
You'll decide: individual or trust?
Individual: You're the only legal owner. Simplest option.
Trust: Multiple people can legally use the suppressor. More complex setup.
Most first-time buyers go individual. Check out our article about NFA trusts if you are interested in multiple people being allowed to use it.
Submit Fingerprints & Photos
You'll need two fingerprint cards and two passport-style photos. Your dealer usually coordinates this—some have everything on-site, others direct you to local services. Takes about 15 minutes.
Pay the Tax Stamp
Historically there has been a $200 you pay to the ATF to own a suppressor. But here's big news: The tax stamp drops to $0 on January 1, 2026.
Wait for Approval
Wait times vary depending on recent laws and events. At the time of writing the process is expected to be 34 - 45 days (On rare occasions we have heard it be as fast as a week), .
Your suppressor sits at the dealer during this time. You can't take it home or use it. Just wait.
Take Possession
When approval comes through, your dealer calls you in. You'll show ID, pick up your suppressor, and get your approved Form 4. Keep that Form 4 safe—it's your proof of legal ownership.
That's it. Go shoot.
What It Costs
Suppressor: $300-$1,500+
Tax stamp: $200 (drops to $0 on January 1, 2026)
Transfer fee: $50-$100 (Varies by dealer)
Total range: $500-$2,000+ depending on your choices.
Which States Allow Suppressors?
42 states allow them. Eight prohibit them (listed above).
Federal approval doesn't override state restrictions. If you move states, notify the ATF using Form 5320.20. Moving to a prohibited state? You'll need to sell or transfer your suppressor before moving.
Always check with your dealer and local laws before purchasing any firearm parts, especially suppressors.
Frequently Asked Questions
Can I use my suppressor while waiting for approval?
No. It stays with the dealer until your Form 4 is approved. Using it before approval is a federal crime.
What happens if I move to another state?
Notify the ATF using Form 5320.20 before moving. Moving to a prohibited state means selling or transferring your suppressor first.
Do I need a suppressor for each firearm?
Nope. One suppressor can work on multiple firearms if the caliber is compatible.
Can someone else use my suppressor?
Individual purchase: only you can possess it. Trust purchase: any trustee can use it legally.
What if my Form 4 gets denied?
Denials are rare if you're legally able to own firearms. Most common reasons: incorrect info, disqualifying criminal history, or fingerprint issues. You can sometimes correct and resubmit.
If it is denied you will not be allowed to take possession of the suppressor.
