THE PULSEFIRE LRT SYSTEM IN AN UNDERBARREL FORM FACTOR
With the same 25-foot reach*, this compact configuration maximizes versatility. Use it fully handheld, mounted to a picatinny equipped device, or even with the Pulsefire Backpack Kit.
ARC IGNITION
Ready when you need it with continuous electric arc ignition. No need to fumble around with a pilot torch to start this party.
BATTERY POWERED
Powered by a rechargeable lithium battery. Integrated circuitry automatically cuts power to the trigger when voltage is low. Simply charge it or swap in a spare to keep bringing the heat.
RAIL MOUNTABLE
A simple lever activated clamp mounted to the top of the UBF secures the rear handle in any number of positions. It just so happens that the handle assembly uses the MIL-STD-1913 profile. Thus, you can clamp it onto any common picatinny rail.
20 SECOND CAPACITY†
Enough firepower to handle most tasks. Expandable to over 4 minutes capacity using the Pulsefire Backpack Kit. Refilling is easy. Use the quick detach clamp and un-mount it from the gun. Lay it on its side and extend the built-in kickstand, and pour in gasoline or a gas/diesel mixture (up to 50% diesel recommended).
BACKPACK CAPABLE
With a simple male-to-male adapter (included with the backpack kit), you can easily connect the hose from the Pulsefire UBF to the external reservoir, boosting your ability to emit fuel and flames to over 4 minutes.
THE SAFEST WAY TO APPLY FIRE
We’ve sold numerous Pulsefire systems to the general public, firefighters, farmers, controlled burn prescribers, and members of the U.S. Forestry Service. While the UBF is focused more on novelty, it’s still capable of typical long range torch use.
BUILT TO LAST
Billet aluminum. Robotic welds. 100% fluoroelastomer seals. We take pride in our products and stand behind them with a lifetime warranty. With over 50,000 sold, there’s a reason we’re #1 in the industry.
FREQUENTLY ASKED QUESTIONS
Most of the FAQ answers relating to the Pulsefire® LRT also apply to the UBF.
Not that we're aware. We tested extensively with a SCAR chambered in .308, a firearm configuration known for being harsh on attached devices, and experienced no failure. We've seen it attached to a .50 BMG and operate without issue.
Not that we're aware. We've had it attached to numerous short barreled firearms without issue, and so have our customers. We have a shield above the unit that helps deflect the blast.
Simply unscrew the hose fitting from the UBF reservoir and thread it onto the included 37 degree male-male adapter. Now you can follow the same instructions that come with the backpack kit - just thread one of the backpack kit's hose ends onto the adapter instead of the fuel pump.
No. The overall housing and fuel tank are welded as one unit.
In order to comply with regulations and avoid requiring permission from the state fire marshal, pyrotechnics license, etc., the Pulsefire LRT is equipped with a short range nozzle. See more details here.
Unfortunately, the same nozzle installed on the Pulsefire UBF results in a very hot flame right by your hands. It is not a comfortable experience. Since the LRT isn't a big seller in California, we made the decision to not sell the UBF in California. You can always install the short range nozzle yourself if you have a standard UBF.
WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov.Specifications for reference only. Minor variations may exist due to manufacturing tolerances. *25 foot reach is under ideal conditions with standard nozzle installed. †Available fuel emission time may vary with fan-type nozzle installed. In our testing, a 30% increase is typical.

Pulsefire® UBF (Underbarrel Flamethrower)
Q & A
For the UBF, it's unlikely. We originally looked at designing it around a removable reservoir like the LRT, but the overall packaging and positioning of the components, particularly the trigger switch, resulted in only one good way to ergonomically organize it all. It would require a significant redesign of many parts, and considering the UBF's ability to mount on a rail was always meant to be a novelty, a dedicated backpack system design was never the priority... We do have a couple new products coming out that will expand the lineup to provide more options for specific tasks, but the UBF is likely to continue to be the same design as today.
It was designed specifically for gasoline and gasoline-diesel mixtures, but it should be fine as long as the fuel remains low viscosity (thin).
For the UBF, unfortunately, no. We are actively working on exporting the LRT and accessories internationally, however.

What a let down- This thing is terrible. I received one as a birthday gift and completely underwhelmed. It dribbles fuel and barely shoots flame. I followed the troubleshooting video and that didn’t help. Don’t waste your money on buying one.
Looks like a pump encountering high resistance or a partially stuck check valve. We don’t have a troubleshooting video, so I’m not sure what you watched, but we do have a written troubleshooting guide, which is extremely thorough – I wrote it. As you know, we have a lifetime warranty, and we include a ton of documentation about it, including a bright orange flyer stating that if you experience any problems, “GIVE US THE OPPORTUNITY AND WE WILL MAKE IT RIGHT”. We mean it. We hate to see a problem arise, but we’re always happy to fix it. If we can’t resolve it remotely, we pay for all the shipping, parts, and labor to fix it! Repairing anything that goes wrong on these is *extremely* easy. Things happen; we can’t prevent a pump from going bad, we can only minimize the chance. If you look at any automotive fuel pump reviews *anywhere* across the internet – you’d think every fuel pump out there is awful! Our issue rate has been a tiny fraction of a percent over the many years we’ve produced these, and if there is an issue, we rapidly resolve it and get your product back in action to continue working as it should. If it’s not pump related, the check valve may have simply been over-torqued, which binds the piston inside, limiting its ability to open wide enough for proper flow. Either way, we would take care of it faster than any warranty experience you’ve ever had with any other company. There’s a reason we have over 825 physical retailers, government/forestry users, and over 50,000 sold, and that wouldn’t be the case if it was a bad product.
I see that you reached out to us via email on June 21, 2024, but never responded to one of our tech’s initial advice/items to check. Most reported issues are resolved by the initial suggestions we offer, as they are typically FAQ items, so the lack of response was not something that raised concern for us. Now that we see your public review 7 months later, we have to mention: We can’t help if there’s no communication. Call us at 772-204-0700 or email us. We’d be glad to provide a return label and have this fixed in less than 24 hours of receiving it. That’s how we operate.
Used this for the first time today and I have to say this was amazing. Had some buddies and family try it. So much fun. Very easy to use and amazingly safe. Gas goes quick so definitely going to be looking at the backpack. Love this thing!!! Listen to the belly laugh of one of the guys using it.
The product works Great!
Who ever buys the UBFT will be very pleased with the purchase. The UBF fun to operate especially when firing an AR or shotgun.
The battery holds up for several loads. I’m at 10 refills of fuel and battery charge is at 11.8 volts.
Buy one or two. You won’t be disappointed.
this is a well designed, all-business piece of equipment; good welding and powder coated finish; couldn’t find a single aspect that is not necessary to the function of the device; solid packaging, easy to assemble; best single-fuel (no pilot light) thrower I could find
Just fun.. more fun.. and more fun
