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.

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.

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
This thing is the real deal!!
Has great feel as a solo set up!
Adds some weight to the rifle but come with and awesome quick disconnect to picatanny!
I am totally impressed! I received my pulse fire UBF yesterday. I ran 7gallons of various fuel mixtures without the backpack, refueling after each 20second burst. I can’t wait for the backpack to get here! Attaching this to my rifle was insanely cool! People were laughing and smiling and having the time of their lives shooting this thing! We had ages 10-60 years old all equally happy and able to use! The ease of use and fun of this thing is unmatched. It’s a rare case where it is actually cooler and more fun than it looks! After 7 gallons and 3 hours of use, the battery was still at 11.0. Incredible! Thank yall so much!
