Missing a DHS to hit 10, to be able to run it. Best way I can see to make it workable is to switch to an AC20 instead of LBX, and de-armor the right side. Lets you carry two tons of ammo too, if you're ok having no head armor. You could also move the ton of ammo from the CT to one of the legs, and put the SNPPC in the CT, for zombie potential.
That’s rather embarrassing. I started with a STD200 and forgot to add a heatsink when i dropped down. I love your version, though. It never even occurred to me to keep both weapons on the same side.
