A disruptor rifle (likewise with several models) is a nISwI' beH [...] The more general term pu', "phaser", may also apply to the Klingon disruptor, but it is used just as often to refer to the Romulan disruptor, Federation phaser, and other similar devices. Since the word is short, pu' is heard frequently — even more frequently than nISwI' — especially in the throes of combat, in such formations as pu'HIch (phaser pistol), pu'beH (phaser rifle)... The verb used for shoot when referring to disruptors is bach. (KGT, p. 56)
