The Bach'Hich assault disruptor is a heavier Klingon disruptor rifle that is deadlier in combat. At least some examples of the weapon used energy cells as ammunition, and consumed them far more quickly than the standard disruptor rifle. They were capable of vaporizing a humanoid target, and had at least two settings. (TNG video game: Klingon Honor Guard)
