CUBES

Like all machine guns; Bastion. Unless you are super unlucky with overload stats and get no max ammunition, in that case run Resilience.

OL GEAR

You want 2 good lines of max ammo capacity (or 3 if unlucky with % rolls). After that, focus on Elemental DMG and ATK. You can get crit and hit rate lines as fillers.
