This seems to work fairly well. Two fire groups on the UAC's to avoid ghost heat, ofc. I hope you enjoy it, critical feedback welcome...
Could change one of the uac 10s into a 5 and not have to worry about ghost heat, which also frees space for more DHS. Uacs are hotter than smurfy gives them credit for due to the double tap, I'd aim for about 50% cooling.
How about LBX10? No jams, cooler and the cool down matches up with the UACs. You can put it in the arm to help with lights. I would consider moving the ammo out of the shoulder zeppelins. or
