NFA Transfer Guide: How to Buy a Suppressor, SBR, or Machine Gun Online

Buying a suppressor, short-barreled rifle (SBR), or other NFA item online is legal — but the process is significantly more involved than a standard FFL transfer. You need the right paperwork, the right dealer, and a lot of patience. Here’s a complete breakdown of how NFA transfers work, what it costs, and what to expect.

What Is an NFA Item?

The National Firearms Act of 1934 regulates certain categories of firearms and devices that require federal registration and a tax stamp before you can legally possess them. NFA items include:

• Suppressors (also called silencers) — sound-reduction devices attached to a firearm’s muzzle
• Short-Barreled Rifles (SBR) — rifles with a barrel under 16 inches or overall length under 26 inches
• Short-Barreled Shotguns (SBS) — shotguns with a barrel under 18 inches or overall length under 26 inches
• Machine Guns — firearms that fire more than one round per trigger pull. Civilian-transferable machine guns must have been manufactured before May 19, 1986 (pre-86 transferable MGs). These are rare and expensive ($10,000–$50,000+).
• Any Other Weapons (AOW) — miscellaneous concealable firearms (pen guns, certain pistol-grip shotguns, etc.)
• Destructive Devices (DD) — explosive devices, grenade launchers, etc. Rare for civilian ownership.

The NFA Transfer Process: Step by Step

Unlike a standard FFL transfer that takes a few minutes at pickup, an NFA transfer involves federal paperwork and waiting months for ATF approval. Here’s the full process:

1. Find an NFA item to buy. You can purchase NFA items through licensed Class III dealers (also called SOT — Special Occupational Taxpayer dealers). Some items are also available from manufacturers and distributors. When buying online, the item ships to your local Class III SOT dealer, not to you.
2. Find a local SOT/Class III dealer. Not all FFLs handle NFA transfers. You need an FFL with a Class III SOT designation. Use GunTransfers.com to find NFA dealers near you. Confirm they handle the specific type of NFA item you’re purchasing.
3. Choose: Individual or Trust. You can register NFA items under your name individually or under an NFA gun trust. Trusts allow multiple authorized users (co-trustees) to possess the item, which is useful for married couples or households where multiple people may handle the item. Trusts also simplify the process if you die (the trust continues to own the item).
4. Complete ATF Form 4 (Transfer of NFA Item). Your Class III dealer will walk you through completing ATF Form 4. For individual transfers, you’ll need: passport photos, your signature, your Chief Law Enforcement Officer (CLEO) notification (note: CLEO approval is no longer required as of 2016 — only notification/copy), and your fingerprints on FBI Form FD-258 cards.
5. Pay the $200 tax stamp. Most NFA items require a $200 federal tax. AOWs are the exception ($5 tax). The tax is paid when you submit Form 4 to the ATF.
6. Wait for ATF approval. This is the hard part. After submission, your Form 4 enters the ATF’s approval queue. Current wait times for individual e-file Form 4 submissions run approximately 6–12 months. Paper Form 4 submissions take significantly longer. Trust e-file submissions are often faster — sometimes 3–6 months.
7. Pick up your NFA item. When your approved Form 4 comes back (with the ATF stamp), your dealer will notify you. You must present your approved stamp and pick up the item. Keep a copy of the approved Form 4 with the NFA item at all times.

Individual vs. NFA Trust: Which Should You Use?

This is one of the most common questions NFA buyers face.

Individual transfer is simpler to set up and costs nothing beyond the $200 tax stamp. However, only you can legally possess the item — if you leave it at home and your spouse touches it, that’s technically illegal possession. If you die, the estate must go through another transfer process.

NFA gun trust requires setting up a legal trust (many attorneys do this for $100–$400, or services like Silencer Shop’s trust offer it for less). The trust allows multiple co-trustees to legally possess the item, and it passes cleanly to the trust’s beneficiaries without another ATF transfer. If you plan to share the item with a spouse, family member, or hunting partner — a trust is worth the extra setup.

Most experienced NFA buyers prefer trusts for the flexibility they provide, especially for suppressors used on multiple firearms.

NFA Transfer Fees at the Dealer

In addition to the $200 ATF tax stamp, your Class III dealer will charge a transfer fee. NFA transfer fees are typically higher than standard FFL transfers because of the additional paperwork, fingerprinting, and extended relationship (you’re waiting months with the dealer):

• NFA transfer fee: $50–$150 depending on the dealer and item type
• Fingerprint cards: Some dealers charge $10–$25 for fingerprinting; others include it
• Trust setup: If you need an NFA trust, budget $100–$400 for an attorney, or use an online service
• Storage fee: Some dealers charge a monthly storage fee if pickup is delayed after the stamp arrives. Ask upfront.

Which States Allow NFA Items?

NFA items are legal in most states, but several states ban specific classes:

• Suppressors banned in: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island, and Washington D.C. (as of 2026 — verify current state law before purchasing)
• Machine guns: Legal for pre-86 transferable MGs under federal law, but some states restrict or ban them
• SBRs/SBS: Banned in California, Illinois, and a handful of other states with assault weapon laws

Always verify your state’s current NFA law before purchasing. State laws change, and your Class III dealer should be familiar with your state’s restrictions.

Buying a Suppressor Online: How It Works

Suppressors are the most commonly purchased NFA items for civilian buyers. Here’s the specific workflow for an online suppressor purchase:

1. Buy the suppressor from an online dealer (Silencer Shop, Brownells, GunBroker NFA section, Buds Gun Shop NFA, etc.)
2. The suppressor ships to your local Class III SOT dealer, not to you
3. Your dealer holds it while the Form 4 paperwork processes through the ATF
4. After approval (6–12 months), you pick it up with your approved tax stamp in hand

Services like Silencer Shop’s kiosk network have simplified the fingerprint and Form 4 process significantly — their kiosks at participating dealers let you complete the paperwork in minutes rather than requiring paper forms by mail.

NFA Transfer FAQ

How long does an NFA transfer take?

Current ATF processing times for Form 4 transfers (e-file) run 6–12 months for individual transfers and 3–6 months for trust transfers. Paper submissions take considerably longer. Check the ATF’s current wait times at the ATF website or community trackers like nfatracker.com.

Can I shoot my suppressor while the Form 4 is pending?

No. You cannot legally possess the NFA item until your Form 4 is approved and you have received the approved tax stamp. The item must remain at the dealer during the entire waiting period.

What is a “tax stamp”?

The $200 NFA tax stamp is the federal excise tax required to transfer or make an NFA item. The “stamp” is the approved ATF Form 4 returned to you — it’s a signed, stamped document you must keep with the NFA item. You should carry a copy when transporting the item.

Do I need a background check for an NFA transfer?

Yes. The ATF runs a thorough background check as part of the Form 4 process — more thorough than the standard NICS check for regular firearms. If you’re prohibited from owning a firearm, you cannot obtain an NFA item.

Can I take my suppressor or SBR across state lines?

For suppressors and AOWs, no advance notice is required for interstate transport (as of 2024). For SBRs and SBSs, you must notify the ATF in advance using ATF Form 5320.20 before crossing state lines. Machine guns require prior approval. Always verify current ATF rules before traveling with any NFA item.

What happens if I move to another state after getting an NFA item?

If you move to a state where your NFA item is legal, you must notify the ATF using Form 5320.20 before transporting it to your new state. If you move to a state where the item is illegal, you must transfer it to another legal owner or to a dealer before the move.
