The weapon itself used to be one of my favorites especially for d1, not really used at all from what I am aware of. Just my personal opinion on it is swap it to the energy slot, there is only one linear fusion that is used outside of this and it happens to be a kinetic slot. I just really look at it from a variety end.

Per shot it’s.... decent? Could be a lot worse I guess. But regardless, it just doesn’t really make a lot of sense as a heavy weapon.
