In stock
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.

How do you mount the Pulsefire® UBF to a gun?
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.
If it’s mounted to a gun, how do you refill it?
Use that quick detach lever clamp and un-mount it from the gun. Lay it on its side and extend the built-in kickstand, which keeps the tank as level as possible, letting you fill things up to the brim safely and efficiently.
The UBF can also use the Pulsefire Backpack Kit.
With a simple male-to-male adapter (included with the backpack kit), you can easily connect the hose from the Pulsefire UBF to the backpack reservoir, boosting your ability to emit fuel and flames to over 4 minutes.
APPLICATIONS
Aside from it being extremely fun to use, the Pulsefire was developed for numerous practical purposes:
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 handheld 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.
