Disintegrators in necromunda have Unstable, a rule so notoriously shitty that most people won't even consider using a weapon that has it unless they've got a rule that let's them ignore it or at least re-roll ammo checks.

The orrus spyre hunter is the only model that has access to them and is their most expensive weapon option and it has a chance of making them go out of action instantly with no wound, save or injury roll, and potentially permanently killing a 350 point gang member.
