Suppressors, SBRs, machine guns, and the legal structures that own them. A plain-English introduction to Title II firearms — what they are, how to acquire them, and when a gun trust makes sense.
Not legal advice. NFA law is federal but interacts with state law, and enforcement details change. Consult a qualified NFA attorney before acquiring Title II items or setting up a gun trust.
The National Firearms Act of 1934 is the federal law that regulates certain "dangerous weapons" through taxation and registration. It was originally passed in response to gangster-era violence and has been amended several times since.
NFA doesn't ban the items it covers — it imposes registration requirements, transfer taxes, and possession restrictions. Items legal to own under NFA are often called Title II firearms (distinguished from Title I, which covers ordinary civilian firearms).
To legally possess an NFA item, you must:
Title I covers ordinary firearms: handguns, rifles, shotguns, and their ammunition. Regulated under the Gun Control Act of 1968. Most firearms in the US fall under Title I.
Title II covers the items added by the National Firearms Act. These are the ones most people mean when they say "NFA items."
If you own a Glock, an AR-15 with a 16" barrel, or a deer rifle, you own Title I firearms. Nothing in this guide applies to you unless you're also interested in acquiring Title II items.
NFA covers six specific categories of items:
| Category | Abbr. | What it is | Stamp |
|---|---|---|---|
| Suppressor (Silencer) | SIL | A device that muffles the report of a firearm. Single-use attachment or permanent. | $200 |
| Short-Barreled Rifle | SBR | A rifle with a barrel under 16" or overall length under 26". | $200 |
| Short-Barreled Shotgun | SBS | A shotgun with a barrel under 18" or overall length under 26". | $200 |
| Machine Gun | MG | Any firearm capable of firing more than one round per trigger pull. Post-1986 MGs banned to civilians. | $200 |
| Any Other Weapon | AOW | Catch-all for concealable items like pen guns, cane guns, smooth-bore pistols, and certain disguised firearms. | $5 |
| Destructive Device | DD | Explosives, incendiaries, grenades, bombs, and firearms with bore over 0.5" (except shotguns). Extremely rare in civilian hands. | $200 |
For the average NFA owner, the relevant categories are suppressors, SBRs, and occasionally SBSs and pre-1986 machine guns. AOWs and DDs are niche.
You buy an NFA item through a special class of FFL dealer called an SOT (Special Occupational Taxpayer). The rough process:
The item is registered to you — or to your gun trust — from that point on. You cannot lend it to friends, move it across state lines without notice, or transfer it without another approved Form 4.
Three ATF forms are the backbone of NFA paperwork:
A gun trust is a revocable living trust specifically designed to own firearms — usually Title II items, but sometimes Title I too. It's a private legal entity that holds title to the firearms you contribute to it.
During your lifetime, you're the grantor, the trustee, and the beneficiary — meaning you have full control. You can add or remove items, add or remove trustees, amend the trust, or dissolve it. When you die, successor trustees you've named take over.
The reason gun trusts are popular among NFA owners is that they solve several problems that plague individual NFA registration:
You can register NFA items to yourself individually or to a gun trust. Both are legal. The right choice depends on how you plan to use and pass on the items.
Under 27 CFR 479.11, a "Responsible Person" of a gun trust is anyone who possesses the authority to direct the trust's actions or exercise dominion over trust property. In plain English: the grantor, co-trustees, and sometimes beneficiaries.
Each Responsible Person must submit the following with any new NFA acquisition under the trust:
These requirements were added in 2016 (ATF Rule 41F) and effectively equalized the process for individuals and trusts. Prior to 41F, trust registration avoided fingerprinting; now it doesn't.
You have three broad options for creating a gun trust:
The gold standard. An attorney who specializes in NFA work will draft a trust tailored to your state, your items, your family situation, and your goals. They'll handle Schedule A (responsible persons) and Schedule B (property) correctly, advise on successor trustees, and be available for future amendments.
Some dealers offer boilerplate trusts bundled with suppressor purchases. These are legally valid but generic — they don't know your family, your backup plans, or edge cases. Fine for a first suppressor; worth upgrading to attorney-drafted if you plan to accumulate multiple items.
Not recommended. Gun trust law is specific, and the common trust templates online don't account for NFA requirements or state-specific probate rules. The $200 you save drafting it yourself is a bad trade against the risk of a legally defective trust.
Whether you register NFA items individually or through a trust, you need to maintain organized records:
Scattered across folders, emails, and a safe, this paperwork becomes unmanageable. During an audit, an inheritance, a trust amendment, or a transfer — that's when organized records become critical.
Gun Trust plan is $299/yr — less than the tax stamp on a single suppressor. Every stamp, trust document, and responsible person in one encrypted place.
