Like I said, "belted ammo" does not equal "weapons without (belt) capability become (belt) loaded when mounted in a heavy weapon mount"; this is absolutely not stated anywhere in the rules. As such, this is definitely something to clarify with one's GM; that's all I'm saying.
Also, laser weapons and the Thunderstruck actually have somewhat pitiful AP values when one considers certain weapons using the Bulls-Eye Double-Tap/Burst action from Run & Gun.
Terracotta Arms AM-47: 15P -4AP. With Bulls-Eye Burst (Semi-Automatic Burst), base AP triples to -12 (plus additional -4 from APDS, for a total of -16AP, depending on one's reading of the rules)
Barret M122: 14P -6AP. With Bulls-Eye Burst, base AP triples to -18 (plus additional -4 from APDS, for a total of -22AP, depending on one's reading of the rules)
