Optimized your build: (endo instead of ferro and armor/ammo placement mostly) You might also want to look into 3LLas as a swap from 2 LPLas for more alpha strike, max DPS, and range (at the cost of heat efficiency). Also, if XL pops are holding you back, a STD300 build would look quite similar, with less JJs and more DHS.
Thanks, I've tried 3xLL but heat seems to be a bit of an issue. I dropped a heat sink for more AC5 ammo. Thus 120 of each ammo type.
