Frequently Asked Questions

The XM42 is available for sale online through our official distributor, and can be found at local dealers across the country! See the dealer locator here!
The XM42 is currently only able to be shipped to United States addresses. We do not have exporting authorization, and exporting a flamethrower is a tricky situation.
Aside from numerous standard powdercoating options, we also offer custom Cerakote-based finishes through our partner, Blowndeadline Custom. To order, simply contact sales@preppergunshop.com with your request and they will gladly help make it happen.
There are generally no restrictions on flamethrower ownership in the United States. However, we are currently aware that California and Maryland have legislation regarding flamethrowers. The city of Warren, Michigan has also prohibited possession/use/sale/manufacture.



In California, unlicensed possession of “any non-stationary and transportable device designed or intended to emit or propel a burning stream of combustible or flammable liquid a distance of at least 10 feet” H&W 12750 (a)—is a misdemeanor punishable with a county jail term not exceeding one year or with a fine not exceeding $10,000 (CA H&W 12761). Licenses to use flamethrowers are issued by the State Fire Marshal.

In Maryland, flamethrowers fall under the state definition for a destructive device and would require an NFA tax stamp for possession.

Check with your local laws before ordering. It is your responsibility to understand and abide by all country, state, and local regulations. We ship anywhere in the United States; it’s up to you to ensure it’s legal in your area.

This device is solely intended for entertainment and utility purposes only. A flamethrower is a fun device for responsible adults and has numerous practical purposes. Be safe, be smart.

Aside from simply being spectacular displays, there are numerous practical purposes for the ability to send fire any measurable distance:

  • melting snow/ice
  • eliminating weeds between pavement cracks
  • firefighting
  • controlled burns/ground-clearing/agricultural
  • insect control
  • concerts/pyrotechnic event displays
  • bonfire starting

The XM42 is simply an extended-reach torch. It is not a weapon, and it would be foolish to envision it as such. It is a fun device for responsible adults to play with, but also has real-world utility use.

Physics. Does your house explode when you turn on the stove? No? Why’s that? There’s a flame at the end of that pipe that’s filled with highly flammable gas. How scary! You need air to support combustion, though, and quite a lot of it compared to the amount of fuel.

There is not enough air to support sustained combustion inside the narrow pipe and nozzle orifice of our system. Even running on empty with hardly anything coming out, a flame front cannot travel anywhere inside the plumbing in any dangerous manner.

Rest assured, the XM42 was developed from the start with safe use in mind.

The current design produces a stream of flaming fuel up to and beyond 25 feet from the nozzle. We’ve experienced up to 35 feet with certain fuels in our testing.
The current fuel reservoir can allow for over 30 seconds of constant full-on operation (if you so desired). The trigger switch can be operated momentarily or held on as long as desired until the tank is empty.

Our goal was to balance capacity and efficiency to maintain a lightweight and manageable device.

We will offer a special system in the future for those that require even longer burn times with a more ergonomic structure.

Simply turn off the pilot torch knob, open the fuel tank cap, and pour your fuel in. No worries about pressurization or needing to mix any additives.

Officially approved fuels: Gasoline (unleaded), gasoline-diesel mixture, and ethyl alcohol (ethanol).

Firefighters and controlled burn specialists typically use 30-40% gasoline, 60-70% diesel. Diesel won’t burn unless the ambient temperature is extremely high (126°F). The gasoline burning keeps the diesel above its flash point, and the nature of diesel keeps it around long enough to completely incinerate the foliage it is directed at.

No. Why would you want to? Napalm is nasty, thick, and produces a very uneventful flame. Gasoline is flashy, gasoline-diesel is useful, and ethanol looks awesome at night with its translucent blue/orange flame.

The only officially approved fuels are: gasoline (any unleaded), a gasoline-diesel mixture, or ethyl alcohol (ethanol). The core of the XM42 is a tight tolerance, high speed fuel pump, and thickened fuels would likely ruin the components.

Firefighters and controlled burn specialists typically use 50/50 diesel/gasoline in cold temperatures, 60% diesel around room temperature, and 70% diesel if the ambient temperature is high. The gasoline burning keeps the diesel above its flash point, and the nature of diesel keeps it around long enough to completely incinerate the foliage it is directed at.

The XM42 uses a proprietary system, which, at its core, utilizes a high pressure electric fuel pump, powered by a lithium-polymer battery typically used in radio control vehicles. This provides an on-demand fuel stream that eliminates the hassle of dealing with pressurized containers and valves.
Fully charged, the battery will typically hold 12.4-12.6 volts. In our testing, we’ve been able to use the system for at least 25+ tank refills with the voltage still within safe levels (above 10 volts). Your usage may vary based on environmental conditions and tolerances in the batteries themselves. Per the manual, always check voltage before and after use to ensure you have enough power available and the battery is within safe levels.

It is important for lithium polymer batteries to remain above a particular voltage. In this battery’s case, 10 volts is the level where charging is an absolute must. If it drops below 10 volts, it may not recharge, and then we’ll have to replace your battery for the cost of shipping and a new battery and ensure your XM42 is safe and ready to use again.

Nope. It’s hard enough keeping enough in stock for our shipments, unfortunately.

The charger is a basic one that can be found at any hobby shop, though. All you need is one made for a 3-cell Li-Po (lithium polymer) battery. We prefer the Turnigy brand, which is available here on Amazon.

See the “Required Accessories” section on the Product Info page for details.
Yes, the XM42 is offered in both left and right-handed configurations.

If you’re right-handed, order a Right.
If you’re left-handed, order a Left.

On right-handed models, the right hand holds the rear grip with the trigger button, while the left hand holds the forward horizontal support grip. Left-handed models are opposite.

Many have asked about the origination of the name, but the story is quite simple.

Many years ago, when the flamethrower project was initially under research & development, the creator was a fan of the XM8 experimental rifle. The XM designation was simply combined with his favorite/lucky number to create “XM42.”
