This is an Open Box Return Item. Never Used.

The patent-pending Pulsefire UBF is the first commercially available under barrel flamethrower. Not legal in CA or MD. See FAQ for details.

The Pulsefire LRT system in an underbarrel capable form factor.

With the same 25-foot reach* and about 20 seconds of fuel capacity, this compact configuration maximizes versatility. Use it fully handheld, mounted to a picatinny equipped device, or even with the Pulsefire Backpack Kit.

While the UBF is focused more on novelty, it’s still capable of typical long range torch use. However, it is less ergonomic than the standard Pulsefire LRT when it comes to full time utility.

25+ FOOT REACH

Send a stream of fuel and flames up to 25 feet* with the press of a button and the standard nozzle.

LIGHTWEIGHT

Constructed primarily of aluminum, the Pulsefire is compact and easy to handle – only 6 lb empty.

OVER 4 MINUTES OF FIRE

available with the optional 3.3 gallon Pulsefire Backpack Kit; 20 second standard capacity.†

LOW POWER PROTECTION

When the voltage is low, the system will disable the trigger, letting you know it’s time to charge or change the battery.

QUICK CHANGE BATTERY

Easy thumbscrew access to the battery compartment lets you charge or swap out your battery in seconds.

NOZZLE OPTIONS

Nozzles available in our store for California-compliant short-range blasts or full length streams.
