Sawing off the barrel of a shotgun is a federal felony under the National Firearms Act if the resulting barrel is shorter than 18 inches or the overall gun length falls below 26 inches, without first completing the NFA registration process and paying the $200 tax stamp. This is not a gray area. It is a bright-line federal crime.
Most gun owners know the term “sawed-off shotgun” but are fuzzy on exactly where the legal line is. The answer is precise: 18 inches for the barrel, 26 inches overall.
This article covers the full legal framework, the exact measurements that matter, how to legally own a short-barreled shotgun, what the penalties are for getting it wrong, and which states make NFA registration irrelevant because they ban these firearms entirely.
Is It Illegal to Saw Off the Barrel of a Shotgun
Sawing off the barrel of a shotgun to a length below 18 inches is a federal felony under the National Firearms Act (NFA), specifically 26 USC 5861, unless the resulting firearm has been lawfully registered with the ATF and the $200 excise tax has been paid.
The NFA was enacted in 1934, originally to regulate weapons commonly associated with organized crime. Sawed-off shotguns were specifically targeted because their concealability made them effective criminal tools. The law has been in place for over 90 years and has survived every constitutional challenge.
Cutting the barrel of your legally owned shotgun below 18 inches without NFA compliance is not a minor infraction. It is the creation of an unregistered short-barreled shotgun, which is classified as a Title II weapon under federal law. The act of making it, without prior ATF approval, is the offense.
The same rule applies to overall length. Even if the barrel remains at or above 18 inches, a shotgun with an overall length below 26 inches (including stock) is classified as an NFA-regulated item.
Quick Facts:
- Minimum legal barrel length: 18 inches (measured from breech face to muzzle)
- Minimum legal overall length: 26 inches (including stock in any position)
- Governing statute: 26 USC 5845 (definitions), 26 USC 5861 (prohibited acts)
- Penalty for violation: Up to 10 years federal prison and $250,000 fine (26 USC 5871)
- Legal pathway: NFA registration with ATF via Form 1 or Form 4 before modification
Is It Illegal to Saw Off a Shotgun Barrel
Sawing off a shotgun barrel is illegal under federal law the moment the resulting barrel length falls below 18 inches or the overall firearm length drops below 26 inches, without prior ATF registration under the National Firearms Act.
The NFA’s definition of a “shotgun” under 26 USC 5845(d) covers a weapon designed or redesigned and intended to fire a fixed shotgun shell from a shoulder, and is typically smoothbore. When you saw off a shotgun barrel to below the minimum lengths, the resulting weapon becomes a “short-barreled shotgun” (SBS) under 26 USC 5845(a)(2), which is a regulated NFA item.
Creating an NFA item without ATF authorization is a prohibited act under 26 USC 5861(f): “to make a firearm in violation of the provisions of this chapter.” The making itself is the crime, not just the possession. This means even if you immediately register the gun after sawing it, you have already committed the federal offense.
Think of it like a driver’s license: you can’t drive and then get the license. You need the authorization before you act.
The moment the crime occurs:
- The cut: Once the barrel drops below 18 inches without prior ATF Form 1 approval, the federal violation is complete
- Possession afterward: A second and ongoing offense under 26 USC 5861(d)
- Transfer to another person: A third category of violation under 26 USC 5861(e)
- Transportation across state lines: A fourth offense category
Why Is It Illegal to Saw Off a Shotgun
Sawing off a shotgun is illegal under the NFA because a shortened shotgun is concealable under clothing, dramatically harder to trace, and historically associated with violent crime, which Congress determined in 1934 justified strict federal regulation requiring registration and taxation.
The NFA’s legislative history is clear about its purpose. Congress targeted sawed-off shotguns, machine guns, and silencers specifically because they served limited legitimate purposes and were the weapons of choice in the organized crime wave of the 1920s and early 1930s.
A full-length shotgun has obvious legitimate uses: hunting, sport shooting, home defense. A shotgun with a 10-inch barrel is almost exclusively useful for concealed carry of lethal force in a close-quarters setting. Congress drew the line at 18 inches as a reasonable boundary that preserved legitimate use while restricting the most concealable configurations.
The constitutional basis has been tested and upheld. Courts have consistently found the NFA’s short-barreled shotgun restrictions to be a valid exercise of Congress’s taxing and commerce powers. The Supreme Court addressed related issues in United States v. Miller (1939), holding that the Second Amendment does not protect weapons with no reasonable relationship to the preservation or efficiency of a well-regulated militia, and sawed-off shotguns were specifically cited.
Why sawed-off shotguns are specially regulated:
- Concealability: Short barrels fit under coats, in bags, and in vehicles with ease
- Reduced traceability: Modified weapons are harder to trace than factory configurations
- Criminal history: Specific association with organized crime that drove NFA passage in 1934
- Limited legitimate use: Shorter barrels reduce accuracy and range significantly
- Compensating danger: At close range, a shotgun blast is devastating; shorter = more concealable = more dangerous in crime context
What Is the Legal Minimum Barrel Length for a Shotgun
The legal minimum barrel length for a shotgun under federal law is 18 inches, and the minimum overall length is 26 inches, both established by the National Firearms Act under 26 USC 5845. Falling below either measurement without NFA registration creates an illegal short-barreled shotgun.
The 18-inch barrel measurement is taken from the closed breech face to the muzzle. For a double-barrel shotgun, each barrel must meet the 18-inch minimum. The overall length of 26 inches is measured with the stock in its most extended position for folding or collapsible stocks.
These measurements are precise and non-negotiable. An 18.1-inch barrel is legal for a standard shotgun. An 17.9-inch barrel, without NFA registration, is a federal felony. There is no grace period, no honest mistake defense, and no minimum quantity threshold. One inch below the minimum is the same offense as ten inches below.
ATF has specific measurement guidance for how barrel length is determined. For revolving-cylinder shotguns, for example, the measurement method differs. For most pump-action and semi-automatic shotguns, the standard breech-face-to-muzzle measurement applies.
Minimum length requirements at a glance:
| Measurement | Minimum Legal | If Below Without NFA Registration |
|---|---|---|
| Barrel length | 18 inches | Illegal SBS; federal felony |
| Overall length | 26 inches | Illegal SBS; federal felony |
| Stock type for measurement | Extended position for folding stocks | ATF measures fully extended |
| Double-barrel shotgun | Each barrel must be 18 inches minimum | Both barrels measured separately |
Key Takeaway: The 18-inch barrel and 26-inch overall length are the two precise federal thresholds. Below either, without NFA registration, is a federal felony. There is no rounding up.
What Makes a Shotgun Sawed-Off Legally
A shotgun is legally considered “sawed-off” or a short-barreled shotgun (SBS) under federal law when its barrel measures less than 18 inches, or its overall length measures less than 26 inches, as defined by the National Firearms Act under 26 USC 5845.
The legal definition is about measurements, not about how the shortening was accomplished. Whether you used a hacksaw, a miter saw, or a professional gunsmith’s equipment, the result is the same under the law. The manner of modification does not affect legality. Only the final measurements matter.
A shotgun can also become legally “sawed-off” without any cutting at all. If a standard shotgun has its stock removed and replaced with a pistol grip, reducing the overall length below 26 inches, it becomes an NFA item regardless of whether the barrel was touched. The overall length calculation includes the stock configuration, so removing a stock can push a legally compliant shotgun into SBS territory.
This is a frequently overlooked aspect of NFA law. Shotgun owners who modify stocks for home defense configurations without measuring the overall length can inadvertently create an SBS without touching the barrel at all.
Ways a shotgun becomes legally sawed-off:
- Barrel cut below 18 inches: Most obvious; the classic sawed-off configuration
- Stock removal reducing overall length below 26 inches: Less obvious but equally regulated
- Both barrel shortening and stock modification: Double violation if both cross minimums
- Factory short-barrel shotgun (pistol grip shotgun): Legal if manufactured as AOW or SBS with NFA registration
- Adding barrel section that still leaves total below 18 inches: Still illegal if overall result is under minimum
What Is Considered a Sawed-Off Shotgun Under Federal Law
Under federal law, a sawed-off shotgun is formally classified as a “short-barreled shotgun” (SBS) under 26 USC 5845(a)(2), defined as a shotgun with a barrel length of less than 18 inches or an overall length of less than 26 inches, or any weapon made from a shotgun meeting those dimensions.
The NFA’s definition covers three categories of SBS. First, it covers a shotgun with a barrel under 18 inches. Second, it covers a shotgun with an overall length under 26 inches regardless of barrel length. Third, it covers “any weapon made from a shotgun” if it falls within those dimensions, which captures modified configurations that may not technically qualify as a “shotgun” in their final form.
The “any weapon made from a shotgun” language is important. A shotgun with its stock removed that becomes a one-handed weapon is often classified as “Any Other Weapon” (AOW) under 26 USC 5845(e) rather than a short-barreled shotgun. AOWs are also NFA items but are taxed at a lower rate ($5 versus $200 for transfer). The classification depends on the specific configuration.
ATF letter rulings and published guidance address specific configurations, and the agency has changed positions on some configurations over the years. For any ambiguous configuration, ATF’s Firearms and Ammunition Technology Division (FATD) issues formal classifications.
Federal SBS classification categories:
| Category | Definition | NFA Classification |
|---|---|---|
| Short barrel | Shotgun with barrel under 18 inches | Short-Barreled Shotgun (SBS) |
| Short overall | Shotgun with overall length under 26 inches | Short-Barreled Shotgun (SBS) |
| Weapon made from shotgun | Modified shotgun meeting SBS dimensions | SBS or AOW depending on configuration |
| Pistol grip only shotgun | Stock removed; one-handed use intended | Typically AOW |
| Factory short-barrel | Manufactured as SBS from factory | SBS (registered as manufactured) |
Can You Legally Own a Sawed-Off Shotgun
You can legally own a sawed-off shotgun (classified as a short-barreled shotgun) in the United States if you comply with the National Firearms Act, which requires ATF registration, payment of a $200 tax stamp, a background check, and residency in a state that permits NFA items.
This surprises many people who assume sawed-off shotguns are completely banned. They are not banned. They are heavily regulated. The NFA creates a legal pathway to own what would otherwise be an illegal weapon. That pathway involves federal registration, background checks, and a waiting period.
There are two ways to legally acquire an NFA-registered SBS. First, you can purchase a factory-made SBS from a licensed Class III dealer and complete a transfer via ATF Form 4. Second, if you own a legally compliant shotgun and want to shorten the barrel, you can file ATF Form 1 (application to make and register a firearm) and receive approval before making any modification.
The second pathway is critical: Form 1 approval must come before any modification. Filing after the fact, or hoping approval will arrive before you get caught, is not a legal strategy. The modification without prior approval is the federal felony.
Legal SBS ownership requirements:
- Federal background check clearance (no felony convictions, no prohibited person status)
- ATF Form 4 (purchase from dealer) or Form 1 (manufacture yourself); both require $200 tax
- Fingerprints and photograph submission to ATF
- Chief Law Enforcement Officer (CLEO) notification or approval depending on method
- NFA trust or individual registration
- Residency in a state that permits NFA items (not all states do)
- Wait for ATF approval before taking possession or making modification
How to Legally Shorten a Shotgun Barrel NFA
Legally shortening a shotgun barrel through the NFA process requires filing ATF Form 1 (Application to Make and Register a Firearm), paying a $200 tax, passing a background check, receiving ATF approval, and only then making the modification to the barrel.
The Form 1 process is the legal pathway for an individual gun owner who wants to convert their existing shotgun into an NFA-registered SBS. It is not the same as buying an SBS; it is the process for making one from a gun you already own.
The Form 1 application requires the manufacturer’s name and address (which is you, if making it yourself), a description of the firearm, the serial number, and the planned modification. You submit fingerprints and a photograph. You pay the $200 tax. Then you wait. ATF processing times for Form 1 applications in recent years have ranged from a few months to over a year depending on workload.
The approval is a tax stamp that you receive and must keep with the firearm at all times. Only after receiving the approved Form 1 can you legally modify the barrel. Cutting the barrel before approval arrives is a federal felony.
Form 1 process steps in order:
- Verify your state allows NFA items and SBS specifically
- Complete ATF Form 1 (eForm 1 available electronically via ATF portal)
- Submit fingerprints, photograph, and $200 tax payment
- Submit CLEO notification or get CLEO approval if required
- Wait for ATF approval (do not touch the gun for modification during this period)
- Receive approved Form 1 with tax stamp
- Make the modification; measure to confirm compliance
- Keep approved Form 1 with the firearm at all times
NFA Tax Stamp for Short-Barreled Shotgun
An NFA tax stamp for a short-barreled shotgun costs $200 and is required for every transfer or manufacture of an SBS, whether you are buying one from a dealer (ATF Form 4) or making one from an existing shotgun (ATF Form 1).
The $200 tax stamp is technically an excise tax levied under the NFA on the making or transfer of NFA-regulated items. It has been $200 since the NFA was amended in 1968. It does not adjust for inflation, meaning the real cost has decreased significantly over 50 years. But the regulatory requirement remains unchanged.
The tax stamp is specific to each transaction. If you buy an SBS, that transfer costs $200. If you later sell or transfer that same SBS to another person, they must complete a new Form 4 and pay another $200. The tax is per transfer, not per firearm.
Some NFA items have a lower transfer tax. AOW items (Any Other Weapon) transfer at $5. The $200 tax applies to SBS, short-barreled rifles, machine guns, destructive devices, and suppressors.
NFA tax stamp facts:
| Item | Transfer Tax | Make Tax (Form 1) |
|---|---|---|
| Short-Barreled Shotgun (SBS) | $200 | $200 |
| Short-Barreled Rifle (SBR) | $200 | $200 |
| Suppressor | $200 | $200 |
| Machine Gun | $200 | $200 (pre-1986 only; new manufacture banned) |
| Any Other Weapon (AOW) | $5 | $200 |
| Destructive Device | $200 | $200 |
Key Takeaway: The NFA process is the only legal pathway to own or create a short-barreled shotgun. The $200 tax and ATF Form 1 or Form 4 must be completed and approved before any modification or possession. Doing it in reverse order is a federal felony.
Penalty for Possessing a Sawed-Off Shotgun
The federal penalty for possessing an unregistered sawed-off shotgun under 26 USC 5871 is up to 10 years in federal prison and a fine of up to $250,000 per violation, making it one of the most severely penalized firearm offenses in federal law.
These penalties apply for each separate offense under 26 USC 5861. The prohibited acts section covers possession (5861(d)), making (5861(f)), transferring (5861(e)), transporting (5861(g)), and several other actions. Each offense is separately charged, meaning someone who illegally makes and then possesses and then transports an unregistered SBS has committed three separate federal offenses, each carrying up to 10 years.
Federal sentencing for NFA violations is further affected by the US Sentencing Guidelines. A person with no prior criminal history convicted of possessing an unregistered SBS may face a guideline range of 18 to 24 months at the low end, while someone with criminal history, or where the offense involved additional criminal conduct, faces substantially longer sentences.
State-level charges often accompany federal NFA charges. Many states have their own illegal weapons statutes that overlap with federal NFA violations. A person arrested for possessing a sawed-off shotgun in California, Illinois, or New York will face both federal NFA charges and state weapons charges, potentially doubling the sentencing exposure.
Federal penalty structure for NFA violations:
| Violation (26 USC 5861) | Maximum Imprisonment | Maximum Fine |
|---|---|---|
| Possession of unregistered SBS (5861(d)) | 10 years | $250,000 |
| Making unregistered SBS (5861(f)) | 10 years | $250,000 |
| Transferring unregistered SBS (5861(e)) | 10 years | $250,000 |
| Transporting unregistered SBS (5861(g)) | 10 years | $250,000 |
| Importing unregistered SBS (5861(k)) | 10 years | $250,000 |
How Many Years in Prison for a Sawed-Off Shotgun
Possessing, making, or transferring an unregistered sawed-off shotgun carries a maximum federal prison sentence of 10 years per offense under 26 USC 5871, with actual sentencing determined by US Sentencing Guidelines, prior criminal history, and any aggravating conduct.
For first-time offenders with no prior criminal history convicted only of possessing an unregistered SBS, federal sentencing guidelines typically suggest 18 to 30 months, depending on specific offense characteristics. Judges have discretion to depart from guidelines, and some defendants receive probation while others receive sentences above the guideline range.
The 10-year maximum becomes more relevant when NFA violations accompany other serious charges. Using a sawed-off shotgun in connection with a drug trafficking offense, robbery, or other violent crime triggers mandatory minimum sentencing enhancements that can result in decades of imprisonment.
The Armed Career Criminal Act (ACCA) applies when a defendant has three prior convictions for violent felonies or serious drug offenses. An ACCA-qualifying defendant convicted of a firearms offense faces a mandatory minimum of 15 years. Possessing a sawed-off shotgun after prior felony convictions creates this exposure.
Prison time factors for sawed-off shotgun charges:
- First-time offender, possession only: Guideline range typically 18 to 30 months; some receive probation
- Prior criminal history: Substantially increases guideline range
- Use in connection with another crime: Drug trafficking or robbery enhancements add years
- Armed Career Criminal Act (3 prior qualifying convictions): 15-year mandatory minimum
- Multiple NFA violations simultaneously: Each charged separately; sentences may run consecutively
Is Possessing a Sawed-Off Shotgun a Felony
Yes, possessing an unregistered sawed-off shotgun is a federal felony under 26 USC 5861(d), and conviction results in a permanent federal felony record that strips the convicted person of the right to own any firearm for life under 18 USC 922(g).
The felony nature of the offense has cascading consequences beyond the immediate sentence. A person convicted of any federal felony is prohibited for life from possessing any firearm or ammunition under 18 USC 922(g). Subsequent firearm possession after an NFA felony conviction is itself a separate federal felony carrying up to 15 years in prison.
This lifetime firearms prohibition is why NFA violations are treated so seriously. A single conviction for possessing an unregistered SBS eliminates Second Amendment rights permanently for the convicted person under current federal law (absent a pardon or specific legal relief).
State-level felony designations accompany the federal charge in most cases. States including California, New York, Illinois, and Michigan have their own felony weapons statutes that apply to unregistered NFA items regardless of whether federal charges are also filed. A person can be charged under both federal and state law for the same possession without violating double jeopardy protections because they are separate sovereigns.
Felony consequences of NFA possession conviction:
- Federal felony record: Permanent
- Firearms prohibition: Lifetime ban on owning or possessing any firearm (18 USC 922(g))
- Voting rights: Varies by state; many states restrict felons from voting during/after sentence
- Employment consequences: Federal felony conviction affects background checks permanently
- Civil rights: Many states restrict other civil rights for felony convictions
- Military service: Felony conviction bars enlistment
States Where Sawed-Off Shotguns Are Illegal Even With NFA
Nine states ban sawed-off shotguns (short-barreled shotguns) even when they are legally registered under the National Firearms Act, meaning federal NFA compliance does not make them legal in these states: California, New York, Illinois, New Jersey, Hawaii, Massachusetts, Rhode Island, Connecticut, and Delaware.
The NFA creates a federal registration system, but it does not preempt state laws that are more restrictive. States have the authority under the Tenth Amendment to ban NFA items that are federally registered. Owning an NFA-registered SBS in these states exposes the owner to state criminal charges regardless of the federal tax stamp.
California Penal Code Section 33215 prohibits short-barreled shotguns (defined as barrel under 18 inches). The prohibition applies regardless of NFA registration status. New York Penal Law Section 265.02 classifies short-barreled shotguns as “assault weapons” or dangerous weapons subject to felony possession charges.
This means a gun owner who legally registers an SBS through the ATF and then moves to California with the NFA-registered firearm is committing a state felony. The federal registration does not provide protection from California state law.
States that ban NFA SBS items regardless of federal registration:
| State | Key Statute | State Penalty |
|---|---|---|
| California | Penal Code Section 33215 | Felony; up to 3 years |
| New York | Penal Law Section 265.02 | Felony; up to 7 years |
| Illinois | 720 ILCS 5/24-1 | Felony; up to 7 years |
| New Jersey | NJ Stat. 2C:39-3 | Second-degree crime; up to 10 years |
| Hawaii | HRS Section 134-8 | Felony; specific penalties confirmed |
| Massachusetts | GL Chapter 140 Section 121 | Felony; specific penalties confirmed |
Sawed-Off Shotgun Laws by State
State laws on sawed-off shotguns fall into three categories: states that follow only the federal NFA framework and allow NFA-registered SBS, states that impose additional restrictions beyond the NFA but still allow some ownership, and states that ban SBS entirely regardless of NFA status.
The majority of states follow the federal framework. In these states, an NFA-registered SBS is legal to own, possess, transport, and use for lawful purposes. The federal $200 tax stamp and ATF registration satisfy all legal requirements.
A smaller group of states, roughly 9 to 11 depending on specific configuration, ban SBS entirely. These are primarily coastal and Northeastern states with generally stricter firearms regulations.
Some states fall in the middle: they allow NFA items but impose additional permitting, registration, or notification requirements beyond the federal system. These additional requirements must be satisfied alongside the NFA process.
| State Category | Examples | SBS Legal? |
|---|---|---|
| Federal NFA framework only | Texas, Florida, Ohio, Nevada, Wyoming | Yes, with NFA registration |
| Additional state requirements | Some states require state registration | Yes, but additional steps needed |
| Ban regardless of NFA status | California, New York, Illinois, New Jersey | No; state felony to possess |
| Partial restrictions | Some states restrict carry or certain configurations | Ownership yes; carry may be restricted |
Can You Inherit a Sawed-Off Shotgun Legally
You can legally inherit an NFA-registered sawed-off shotgun, but the transfer of the NFA item through inheritance requires filing an ATF Form 5 (tax-exempt transfer for estate purposes) and completing ATF processing, even though the transfer is tax-exempt.
When the owner of an NFA-registered firearm dies, the firearm does not automatically transfer to heirs like a standard firearm. Because it is an NFA item, the transfer must be approved by the ATF. The executor of the estate files ATF Form 5 to transfer the NFA item to the rightful heir. This transfer is exempt from the $200 tax that normally applies to NFA transfers.
The heir must be a legal resident of a state that permits NFA items, must pass an ATF background check, and must not be a prohibited person. If the heir lives in California, New York, Illinois, or another state that bans SBS items, they cannot legally inherit the firearm in their state. Options in that situation include selling the firearm to a state where it is legal or transferring it to someone who can legally possess it.
Critically, heirs cannot possess the NFA item before the Form 5 transfer is approved. Taking possession of an unregistered or in-transfer NFA item before ATF approval is itself a federal crime.
Inheriting an NFA-registered SBS: process:
- Executor files ATF Form 5 (Application for Tax-Exempt Transfer)
- Submit fingerprints and photograph for the inheriting heir
- ATF processes the form (typically weeks to months)
- Upon approval, heir takes legal possession
- Heir must live in a state that permits SBS ownership
- Heir cannot possess the firearm before ATF Form 5 is approved
- Approved Form 5 must stay with the firearm at all times
Is It Legal to Saw Off a Shotgun Barrel
Sawing off a shotgun barrel is legal only when the process follows the NFA’s pre-approval requirements, meaning ATF Form 1 has been filed, the $200 tax has been paid, ATF approval has been received, and the modification keeps the barrel at or above 18 inches and the overall length at or above 26 inches.
The legality is entirely procedural. There is nothing inherently criminal about using a saw near a firearm. The crime is in the timing and the result. Cut the barrel before ATF approval of Form 1: federal felony. Cut it after approval: legal. Leave the barrel at 18 inches or more: legal. Cut it to 17.9 inches: federal felony.
Legal modifications to shotgun barrels that do not trigger NFA issues include shortening a barrel that is already well above 18 inches (for example, cutting a 28-inch barrel to 20 inches for a more compact hunting configuration). As long as the result stays above both minimums, no NFA registration is required.
The barrel must be measured before any cuts, and care must be taken to ensure the final length lands exactly where intended. Measuring error in the wrong direction is a federal crime. Many gun owners who shorten barrels for legal purposes take the work to a licensed gunsmith precisely to ensure accurate measurement and compliance.
Barrel modification legality summary:
| Action | Legal? | Requirements |
|---|---|---|
| Cut barrel from 28 to 20 inches | Yes | No NFA required; above both minimums |
| Cut barrel from 20 to 18 inches | Yes | No NFA required; at minimum |
| Cut barrel from 20 to 17 inches | Only with prior ATF Form 1 approval | NFA SBS registration required first |
| Cut barrel to exactly 18 inches | Yes, if no other length issues | Measure carefully; no tolerance for error |
| Remove stock, shortening overall length below 26 inches | Only with prior ATF Form 1 approval | NFA SBS or AOW registration required first |
Frequently Asked Questions
What is the minimum legal barrel length for a shotgun in the US?
The minimum legal barrel length for a standard shotgun is 18 inches under the National Firearms Act, 26 USC 5845.
The minimum overall length of the shotgun (including stock in extended position) is 26 inches.
A barrel below 18 inches or an overall length below 26 inches without NFA registration is a federal felony.
What is the penalty for possessing a sawed-off shotgun?
The federal penalty for possessing an unregistered sawed-off shotgun under 26 USC 5871 is up to 10 years in federal prison and up to a $250,000 fine per violation.
First-time offenders without other criminal history typically face sentencing guideline ranges of 18 to 30 months.
A conviction also results in a lifetime federal prohibition on owning or possessing any firearm under 18 USC 922(g).
Can you legally shorten a shotgun barrel with an NFA tax stamp?
Yes, you can legally shorten a shotgun barrel below 18 inches, but you must file ATF Form 1 and receive written approval before making any modification.
The $200 NFA tax must be paid and the ATF approval received prior to any cutting.
Making the modification before ATF approval is a federal felony regardless of whether you intended to comply.
Which states ban sawed-off shotguns even with NFA registration?
Approximately nine states ban short-barreled shotguns regardless of NFA federal registration status: California, New York, Illinois, New Jersey, Hawaii, Massachusetts, Rhode Island, Connecticut, and Delaware.
In these states, possessing an NFA-registered SBS is a state felony even though federal registration is otherwise valid.
Moving to one of these states with an NFA-registered SBS creates immediate state criminal liability.
What happens if you inherit a sawed-off shotgun?
Inheriting an NFA-registered sawed-off shotgun is legal but requires ATF Form 5 to be filed by the estate executor before the heir takes possession.
The Form 5 transfer is tax-exempt but still requires ATF processing and background check approval for the heir.
Taking possession before ATF Form 5 approval is a federal crime, and the heir must live in a state that allows SBS ownership.
Closing
The rules around sawed-off shotguns are precise, federally enforced, and not forgiving of mistakes. The 18-inch and 26-inch thresholds are bright lines, and crossing them without prior ATF approval is a federal felony with a 10-year maximum sentence.
