EXPECTED JUNE 2026
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.
25-FOOT REACH*
Light the bonfire, incinerate weeds, and have fun doing it. Reach out with an ignited fuel stream from a safe distance to whatever needs to be lit.
20-SECOND CAPACITY†
Enough firepower to handle most tasks, and expandable to over 4 minutes capacity with the Pulsefire Backpack Kit.
RUNS ON GASOLINE
Lay it on its side, extend the built-in kickstand, and fill the non-pressurized reservoir like any other outdoor tool. Uses gasoline or a gas/diesel mixture (up to 50% diesel).
BATTERY POWERED
Instant-action without pressurized fuel or pilot flames. Rechargeable battery powers the fuel pump and ignition for safe operation.
ON-DEMAND IGNITION
Ready when you need it with continuous electric arc ignition. No need to fumble around with a pilot torch to start this party. Press button, receive flames.
MODULAR
Use standalone with the included handle, or clamp to any picatinny equipped device for underbarrel fun.
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.

FREQUENTLY ASKED QUESTIONS
Most of the FAQ answers relating to the Pulsefire® LRT also apply to the UBF.
Will recoil damage it?
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 customers attach it to a .50 BMG, shotgun, etc. and operate without issue.
My barrel is short. Will the muzzle blast cause harm to the unit?
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.
How do you attach the backpack kit to the UBF?
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.
Is the onboard reservoir removable?
No. The overall housing and fuel tank are welded as one unit.
Will there be a California compliant version?
In order to comply with regulations and avoid requiring permission from the state fire marshal, pyrotechnics license, etc., the Pulsefire LRT was offered with a short range nozzle for California customers. 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. Thus, 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 and want to feel the heat.
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 60,000 sold, there’s a reason we’re #1 in the industry.
* † Additional Notes
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.
Be sure to check our Instructions/Videos pages for more information.

One hell of a way to start a campfire. Also used it to light up some wind rows when they clear cut some of my hunting lease. Easy to use and always puts a smile on your face.
BRIAN C –
Too much fun. Only complaint would be the low fuel capacity. However, the back pack attachment solves that.

When life gives you lemons you make lemonade. But when life give you a flamethrower you slap it onto the bottom of a 12 gauge because this is America and nobody can tell you not too.
