@PyckenZot It's on! Range is overrated. Starting from my 'Barbarian' it's not hard to fit 2x AC20 instead. Hits a bit harder, but a bit worse at range and finishing off.
Not having it in my garage yet, and the ammo count for your AC20s The first means that I'm a bit less interested in making builds for it (except maybe as a goal to aim for), the second means that you can't deal enough damage with your no-jam IS UAC20.
