Exothermic Technologies Pulsefire UBF Green Powder Coated Flamethrower - 25 ft Range, 16" Long, Includes Battery & Charger

The Exothermic Technologies Pulsefire UBF is a battery-powered underbarrel flamethrower built for serious utility work and recreational burn tasks. At 16 inches long and finished in green powder coat, this compact torch mounts directly to any Picatinny-equipped rifle or shotgun, or runs standalone with the included handle. With a 25-foot effective range, it delivers enough reach to safely light bonfires, clear vegetation, and handle controlled burns from a distance—all with the push of a button and none of the fussing around with pilot flames or pressurized fuel canisters.

The Pulsefire UBF runs on gasoline or a gasoline-diesel blend (up to 50% diesel), fed by a rechargeable battery that powers both the fuel pump and the electric-arc ignition system. The non-pressurized reservoir holds 0.25 gallons and delivers roughly 20 seconds of continuous operation—enough for most jobs on its own, or expandable to over 4 minutes if paired with the optional Pulsefire Backpack Kit. Built from aluminum and brass with a Viton seal, the system is engineered for reliability in field conditions. The included 2200 mAh lithium battery and charger get you running right out of the box.

This is a specialized tool with real-world applications: land management, controlled burns, bonfire ignition, and weed suppression all benefit from the precision and safety of electric ignition and standoff range. It's genuinely modular—clamp it to your rifle, use the standalone handle for handheld work, or scale up with the backpack system. Note that the Pulsefire UBF is not legal in California or Maryland, so confirm local regulations before purchase.
