Abstract: A firearm flame thrower combination includes a firearm, a cartridge that is dischargeable from the firearm; and a flame thrower attached to the firearm. The flame thrower has a battery; ignitable fluid; a reservoir holding the ignitable fluid; a nozzle that optionally pivots; a high-pressure pump operable to pump the ignitable fluid from the reservoir and to eject a stream of the ignitable fluid out of the nozzle. The stream is ignitable from muzzle flash exiting the muzzle upon firing of the cartridge in the firearm. Movement of the trigger may automatically activate the high-pressure pump. A radio-frequency controller may be used to emit a radio-frequency signal to start the high-pressure pump. An off switch may be included.
