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.
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.
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.

It’s great. You can tell it’s well made.
Awesome. Exactly as advertised. Except mine doesn’t seem to get more than 10-15 foot range max.

Loved it after I got finished with it. Just need backpack

This is an amazing company. They have been so easy and effortless to order from. I bought my husband the LRT Pulsefire for Christmas and he loves it. One small issue with battery and they replaced instantly without any hassle! The man I talked to when I ordered was so kind and respectful. Highly recommend!
