I did try an Ultra-AC config, but im not sure the AI uses double tap for extra fire power. So this is the best ratio of firepower to heat i could manage. I dont think it makes too much difference if you use Burst Fire or not, but they seem to be more common. The AI will just DPS enemies to death by spreading its damage all over the place, its not efficient but it is effective! I generaly dont pilot the Sand Blaster as its too slow and imprecise, but its a great walking turret for defense missions - and its super reassuring to hear the Dakka go off next to you aaaah so sweet. Put your best stuff in the Torso.
