Hath Blaster
From TARDIS Index File, the free Doctor Who reference.
During the 7 day war on Messaline the Hath warriors armed themselves with powerful blaster rifles. The rifles were black and seemed to be powered by a gas cansister fixed to the base of the weapon. The guns fired a stream of bullets usually accompanied by a plume of flames. These were similar to the rifles used by the human colonists but had a different exterior design. The rifles were the only weapon seen to be used by the Hath. (DW: The Doctor's Daughter)
