Yes, it is legal to own a flamethrower in most US states. No federal law bans civilian ownership, and the majority of states place no specific restrictions on flamethrowers at all. That surprises most people.

The widespread assumption is that a device that shoots fire must be heavily regulated or outright banned. The legal reality is almost exactly the opposite. Flamethrowers are not classified as firearms under federal law, which means the ATF has no jurisdiction over them as weapons.

This guide covers the full legal picture in 2026: the federal classification that makes them broadly legal, which states restrict or ban them, what the penalties look like, and what legitimate uses make these devices popular with farmers, land managers, and outdoor enthusiasts.

Is It Legal to Own a Flamethrower

Yes, owning a flamethrower is legal in most of the United States. No federal statute prohibits civilian ownership of a flamethrower, and the vast majority of US states have no specific law banning or restricting them.

This is genuinely surprising to most people who assume that any device capable of projecting fire must fall under strict weapons regulations. The legal framework simply does not support that assumption at the federal level. Flamethrowers occupy a regulatory gap that the National Firearms Act and related federal weapons laws do not cover.

The states that do restrict flamethrowers are a small minority. California and Maryland are the most notable examples. Even in those states, the restrictions are specific rather than absolute prohibitions in all contexts. In the remaining 48 states, a person can purchase, own, and possess a civilian flamethrower without obtaining any permit, license, or registration.

Quick Facts:

  • No federal law bans civilian flamethrower ownership
  • Flamethrowers are not classified as firearms under federal law
  • The ATF has no jurisdiction over flamethrowers as regulated weapons
  • California and Maryland have state-level restrictions
  • Most states have no specific flamethrower law at all
  • Local fire codes and municipal ordinances may add additional restrictions
  • Commercial flamethrowers like the XM42 and Throwflame devices are sold legally online

Is It Illegal to Own a Flamethrower in the US

No, it is not illegal to own a flamethrower in the US at the federal level, and it is legal in the overwhelming majority of states. Only a small number of states have enacted specific restrictions.

The misconception that flamethrowers are federally banned likely comes from their military connotation. Military flamethrowers were phased out of US forces’ primary arsenals decades ago, and that association with warfare makes people assume civilian ownership must be prohibited. But the weapons laws that prohibit things like automatic machine guns and destructive devices do not include flamethrowers in their definitions.

In the states that do restrict them, the legal exposure varies. California has the most developed regulatory framework, with specific statutes governing flamethrower possession. Maryland restricts them under its dangerous weapon provisions. Outside of those states and a handful of municipalities with local ordinances, owning a flamethrower is no different legally than owning a chainsaw or a pressure washer in terms of regulatory requirements.

Federal legal status summary:

  • National Firearms Act (26 U.S.C. 5845): Does not include flamethrowers in its definitions
  • Gun Control Act (18 U.S.C. 921): Does not classify flamethrowers as firearms
  • ATF jurisdiction: Does not extend to flamethrowers as regulated weapons
  • Federal Explosives Law: Does not cover standard civilian flamethrowers
  • State law: The primary regulatory framework; varies significantly

Are Flamethrowers Legal in the US

Flamethrowers are legal in the US for civilian ownership in approximately 48 states, with no federal prohibition in place as of 2026. The legality stems from federal weapons law’s specific definitions, which do not capture flamethrowers in any regulated category.

The National Firearms Act regulates specific categories of weapons including machine guns, short-barreled rifles, silencers, and destructive devices. A destructive device under 26 U.S.C. 5845(f) includes items like explosive devices, grenades, and rocket launchers. A civilian flamethrower that uses propellant fuel does not meet the destructive device definition as interpreted by the ATF.

The commercial flamethrower market in the US has grown significantly. Companies like Throwflame and Ion Productions (maker of the XM42) sell consumer flamethrowers openly online and ship to most states. These devices are marketed for agricultural use, land clearing, weed control, and outdoor entertainment. Their commercial availability in most states is itself evidence of the broad legal permissibility.

Flamethrower legal status overview:

CategoryStatus
Federal lawNo prohibition; not classified as a firearm
ATF regulationNo jurisdiction; not a regulated weapon
States permitting ownershipApproximately 48 states
States with restrictionsCalifornia, Maryland; possibly others with local ordinances
Purchase processNo federal background check required
Age restrictionsVaries by state; typically 18 or 21

Can You Legally Own a Flamethrower

Yes, you can legally own a flamethrower in most US states without a federal permit, background check, or registration. The purchase and ownership process for a consumer flamethrower is more similar to buying a torch than buying a gun.

No federal form is required for the purchase. No federal waiting period applies. No federal license must be obtained. You order the device, pay for it, and it ships to your door in states where it is legal. The absence of any federal gatekeeping mechanism is unusual for a device of this capability, but it reflects how the law is currently written.

owning a flamethrower

The ownership caveat that matters most is state law. Before purchasing a flamethrower, verifying your state’s specific laws is essential. California residents face specific criminal restrictions. Maryland residents face restrictions under that state’s dangerous weapons framework. And even in permissive states, local ordinances and fire codes can layer on additional rules about where and how the device can be used.

Pre-purchase legal checklist:

  • Verify your state does not have a specific flamethrower restriction
  • Check your county and municipality for local fire codes or dangerous weapon ordinances
  • Review your state’s age restriction for purchasing dangerous or incendiary devices
  • Confirm the seller ships to your state
  • Check local open burn regulations if you plan outdoor use
  • Review homeowner’s insurance policy for coverage implications

Key Takeaway: Flamethrowers are legal to own in most US states with no federal permit required. The main legal variables are state law, local ordinances, and fire codes that restrict where and how they can be used.

Is It Legal to Buy a Flamethrower

Yes, buying a flamethrower is legal in most US states. Consumer flamethrowers can be purchased online and shipped directly to buyers in states where ownership is permitted, with no federal background check, registration, or waiting period.

The commercial market for civilian flamethrowers has expanded significantly since around 2015, when the XM42 became one of the first widely marketed consumer flamethrowers in the US. Several companies now manufacture and sell these devices openly, pricing them from a few hundred dollars to over $1,000 depending on the model and fuel capacity.

The purchase itself triggers no federal reporting requirements. Unlike purchasing a firearm, which requires ATF Form 4473 and a NICS background check, buying a flamethrower requires only payment and a shipping address in a state that permits delivery. Sellers typically screen orders to avoid shipping to California and other restricted states, but no federal mechanism compels this screening.

Consumer flamethrower purchase process:

  • Select a commercial supplier (multiple US-based manufacturers sell online)
  • Confirm your state permits delivery
  • Complete a standard purchase transaction; no federal forms required
  • No background check required
  • Device ships directly to your address
  • State and local laws govern what you can do with it after delivery

Is a Flamethrower a Firearm

No, a flamethrower is not a firearm under federal law. The legal definition of a firearm under both the Gun Control Act and the National Firearms Act specifically requires the use of an explosive to propel a projectile, and a flamethrower does not meet that definition.

Under 18 U.S.C. 921(a)(3), a firearm is defined as any weapon that will or is designed to expel a projectile by the action of an explosive. A flamethrower expels burning fuel, not a projectile propelled by an explosive. The mechanics are entirely different, and the legal definitions do not overlap.

This classification distinction matters enormously for ownership rules. Because flamethrowers are not firearms, none of the federal firearms regulations apply: no background check, no Form 4473, no dealer license requirement for the seller, no prohibited person restrictions. The entire federal firearms regulatory apparatus simply does not apply to flamethrower transactions.

Flamethrower versus firearm legal comparison:

FactorFirearmFlamethrower
Federal definition (GCA 18 U.S.C. 921)Expels projectile by explosive actionDoes not qualify

ATF regulatedYesNo
Background check requiredYes (federal)No
Dealer license requiredYes (FFL)No

ATF Flamethrower Classification

The ATF does not classify civilian flamethrowers as regulated weapons, which means the Bureau of Alcohol, Tobacco, Firearms and Explosives has no jurisdiction over their purchase, ownership, or transfer.

The ATF’s regulatory authority extends to firearms under the Gun Control Act and to certain regulated items under the National Firearms Act, including machine guns, short-barreled shotguns, silencers, and destructive devices. A destructive device under 26 U.S.C. 5845(f) is defined as any explosive, incendiary, or poison gas bomb, grenade, mine, rocket, missile, or similar device. The ATF has not classified standard consumer flamethrowers as falling within this definition.

The incendiary device language in the NFA definition is the closest the statute comes to potentially covering flamethrowers. However, the ATF’s interpretation has consistently treated that language as covering explosive-based devices rather than fuel-propulsion systems. Consumer flamethrowers have been sold commercially in the US for over a decade without any ATF action to classify or regulate them.

ATF regulatory scope and flamethrowers:

  • Firearms (18 U.S.C. 921): Flamethrowers excluded; not projectile weapons
  • NFA items (26 U.S.C. 5845): Flamethrowers not classified as destructive devices
  • ATF ruling on flamethrowers: No specific ruling classifying them as regulated items
  • Commercial availability: Multiple US companies sell them without ATF dealer licensing
  • Import restrictions: Some international models may face import restrictions under separate rules
  • Future reclassification: Possible but has not occurred as of 2026

Flamethrower Laws by State

Flamethrower laws by state range from no restrictions at all in most states to outright prohibition with criminal penalties in California and Maryland. The variation reflects each state’s individual approach to regulating dangerous tools and incendiary devices.

The majority of states have no specific flamethrower statute. In those states, the device is treated like any other tool or piece of equipment. Ownership, possession, and use are governed by general laws that apply to any potentially dangerous item: fire codes, arson statutes, public safety ordinances, and common sense usage restrictions in certain locations.

States with specific restrictions focus primarily on the weapon potential of flamethrowers rather than their agricultural or industrial uses. Even in restrictive states, the motivation for legislation has typically been the concern about flamethrowers as potential weapons rather than opposition to legitimate uses like land clearing or weed control.

State flamethrower legal status:

States Where Flamethrowers Are Illegal

California and Maryland are the two states with the clearest statutory restrictions on civilian flamethrower ownership in 2026. A small number of municipalities in otherwise permissive states may also have local ordinances that effectively prohibit or heavily restrict them.

California has the most developed legislative framework. California Penal Code Sections 12750 through 12758 address flamethrowers specifically. The law prohibits possession of a flamethrower by most civilians but creates exceptions for specific purposes including certain agricultural uses and some professional applications. Unauthorized possession is a criminal offense under California law.

Maryland restricts flamethrowers under its dangerous weapon provisions in the Maryland Criminal Law Code. The state’s approach is to classify flamethrowers as dangerous weapons, which triggers Maryland’s general dangerous weapon possession restrictions. Operating in Maryland with a flamethrower without authorization can result in criminal charges under those provisions.

States with flamethrower restrictions:

States Where Flamethrowers Are Legal

Flamethrowers are legal to own and possess in approximately 48 states without any specific statutory restriction. That broad permissibility reflects the absence of federal regulation and the lack of legislative attention to flamethrowers in most state legislatures.

The states where flamethrowers are explicitly or effectively legal include Texas, Florida, Arizona, Nevada, Idaho, Montana, Wyoming, Colorado, Utah, New Mexico, Oregon, Washington, Alaska, Hawaii, and the vast majority of states east of the Mississippi. In each of these states, a resident can purchase, own, and possess a consumer flamethrower without triggering any specific weapons law violation.

Even in legally permissive states, practical restrictions apply through fire codes and local burn regulations. Many states prohibit open burning during certain periods due to wildfire risk, and using a flamethrower during a burn ban can result in fire code violations even if flamethrower possession itself is perfectly legal. Knowing the distinction between possession legality and use legality matters for anyone who wants to actually operate the device.

States with generally permissive flamethrower laws:

  • Texas: No specific flamethrower statute; legal to own and possess
  • Florida: No specific restriction; fire codes govern use
  • Nevada: No specific restriction; widely available and used
  • Arizona: No specific restriction; popular for agricultural use
  • All other states not specifically restricting: Generally legal

Key Takeaway: Flamethrowers are legal to own in approximately 48 states, with California and Maryland being the primary exceptions. Even in legal states, local fire codes and burn bans restrict where and when they can actually be used.

California Flamethrower Law

California’s flamethrower law is codified in California Penal Code Sections 12750 through 12758, making it one of the few states with a comprehensive statutory framework specifically addressing flamethrowers.

California Penal Code 12750 defines a flamethrower as any non-stationary and non-vehicular mechanical device that is designed or intended to emit or propel a burning stream of combustible or flammable material. Under Penal Code 12751, any person who uses or possesses a flamethrower in California is guilty of a felony, punishable by imprisonment in state prison. The law is not ambiguous on this point.

Exceptions exist. Penal Code 12754 creates exceptions for the military, law enforcement, and certain authorized uses in agriculture, horticulture, and pest control with specific permits. The existence of agricultural exceptions reflects the legitimate weed and pest control applications of flamethrowers, but obtaining the required authorization for those uses requires navigating a permit process.

California flamethrower law specifics:

  • Governing statutes: California Penal Code 12750 to 12758
  • General possession: Felony offense
  • Penalty: Imprisonment in state prison; specific term not confirmed publicly
  • Exceptions: Military, law enforcement, certain permitted agricultural uses
  • Agricultural permit: Required for lawful use in farming contexts
  • Practical result for civilians: Effectively prohibited without specific authorization

Maryland Flamethrower Ban

Maryland restricts flamethrowers under its dangerous weapon laws in the Maryland Criminal Law Code, treating them as dangerous weapons subject to the state’s general dangerous weapon possession provisions.

Maryland’s approach differs from California’s in that Maryland does not have a separate statute specifically named for flamethrowers. Instead, the state’s criminal law framework classifies certain incendiary devices and dangerous weapons broadly, and flamethrowers fall within those classifications under Maryland law. Possessing a dangerous weapon with the intent to harm or in a context where possession creates public safety risk triggers criminal liability.

The penalty structure under Maryland’s dangerous weapon provisions includes misdemeanor charges for simple possession in some contexts and felony charges when aggravating circumstances are present. Maryland courts have treated flamethrowers as regulated dangerous devices rather than ordinary tools, and residents who possess them without specific authorization risk prosecution under the state’s criminal code.

Maryland flamethrower restriction summary:

  • Legal framework: Maryland Criminal Law Code dangerous weapon provisions
  • Specific statute: No dedicated flamethrower statute; covered under dangerous weapon provisions
  • Possession consequence: Misdemeanor to felony depending on circumstances
  • Exceptions: Limited; primarily law enforcement and military
  • Practical effect: Civilian possession effectively prohibited
  • Specific penalty amounts: Not publicly confirmed with precision; range from misdemeanor fines to felony imprisonment

Penalty for Owning an Illegal Flamethrower

The penalty for owning an illegal flamethrower varies by state but can range from misdemeanor fines to felony imprisonment depending on the jurisdiction and the specific charges filed.

In California, which has the most specific statutory framework, unauthorized possession of a flamethrower is a felony under Penal Code 12751. Felony convictions in California can result in state prison sentences. The specific sentencing range depends on the circumstances and whether aggravating factors are present, but state prison time is the potential consequence, not merely a fine.

In Maryland, the dangerous weapon provisions that cover flamethrowers carry varying penalties depending on the specific charge. Misdemeanor dangerous weapon charges in Maryland can result in fines and up to three years imprisonment in some cases. If the weapon possession is connected to other criminal conduct, the charges escalate significantly.

In states without specific flamethrower laws, illegal use of a flamethrower rather than mere possession can result in arson charges if property is damaged, reckless endangerment charges if others are put at risk, or fire code violation fines if burn regulations are violated.

Flamethrower Legal Uses

Flamethrowers have several well-established legal uses in the United States that drive most of the consumer and commercial demand for these devices.

Agricultural use is the most common legitimate application. Farmers and land managers use flamethrowers for weed control, clearing invasive vegetation, managing crop fields before planting, and eliminating pest colonies. These applications are recognized as legitimate in nearly every state, and in California, where possession is otherwise restricted, agricultural use can be authorized through a permit process.

Property maintenance and land clearing are additional common uses. Burning off dry vegetation to reduce wildfire risk, clearing brush from rural properties, and managing overgrown areas are all practical applications. Ice removal from driveways and pathways is a growing use in northern states. Film and entertainment production companies use flamethrowers for special effects under controlled conditions with appropriate permits.

Common legal uses for flamethrowers:

Use CategoryDescriptionLegal Considerations
Agricultural weed controlBurning weeds between crop rowsCheck state burn permit requirements
Land clearingRemoving brush and invasive vegetationLocal burn permit may be required
Pest controlEliminating wasp nests, ant coloniesCheck state pesticide and burn laws
Ice and snow removalClearing driveways and walkwaysGenerally legal; fire safety applies
Film and entertainmentSpecial effects productionRequires production permits
Recreational usePrivate property demonstrationsCheck local fire codes and burn bans

Can You Use a Flamethrower for Agriculture

Yes, flamethrowers can be used legally for agricultural purposes in most US states, and this is one of the most established and legitimate applications for these devices. Agricultural flame weeding is a recognized farming technique that reduces reliance on herbicides and manages weed populations between crop rows.

Flamethrower-based weed control works by applying brief intense heat to weeds, causing cellular damage that kills the plant without necessarily burning it to ash. Organic farmers in particular use this technique as an alternative to chemical weed control. The application is especially useful in corn, soybeans, and other row crops during the window between planting and canopy closure.

Even in California, where civilian flamethrower possession is generally a felony, the state’s Penal Code creates specific exceptions for agricultural, horticultural, and pest control applications. A permit obtained through the appropriate California authority can authorize the use of a flamethrower in qualifying agricultural settings. Other states with no specific restrictions simply require compliance with general open burn regulations, which typically require permits during certain seasons or weather conditions.

Agricultural flamethrower use requirements:

  • California: Specific permit required under PC 12754 exception
  • Most other states: Comply with state burn permit requirements
  • Federal land use: Check with the relevant agency (BLM, USFS) for any additional requirements
  • Fire season restrictions: Most states prohibit open burning during high fire danger periods
  • Local ordinances: Rural county burn regulations apply even in permissive states
  • Equipment specifications: Some states specify maximum flame range or fuel type for agricultural use

Civilian Flamethrower Ownership Rules

Civilian flamethrower ownership rules in 2026 operate primarily through a three-layer framework: federal non-regulation, state statutory variation, and local ordinance application.

At the federal level, there are no ownership rules beyond the general laws that apply to all Americans, such as arson prohibitions if a flamethrower is used to cause damage. No license, permit, background check, or registration exists at the federal level.

At the state level, the rules range from no specific requirements in most states to criminal prohibition in California and Maryland. In permissive states, the practical ownership rules are whatever general laws apply to dangerous tools, fire-producing equipment, and outdoor burning.

At the local level, municipal fire codes and dangerous weapon ordinances can add another layer of restriction. A city might prohibit the discharge of any flammable device within city limits, which would restrict flamethrower use even if state law is permissive. Researching county and municipal rules before purchasing is the most important practical step for anyone considering ownership.

Civilian ownership rules summary by layer:

  • Federal: No permit, no background check, no registration, no license required
  • State (most states): No specific requirement; general laws apply
  • State (California): Criminal prohibition except for permitted exceptions
  • State (Maryland): Dangerous weapon classification; possession generally restricted
  • Local (varies): Fire codes and weapon ordinances may restrict possession or use
  • Insurance: Homeowner’s policies may not cover flamethrower-related incidents
