This looks so noobishly random, it might actually work! Something along the lines of a stock upgrade, but then again, it really isn't. Drop the ERMLs to SPLs for better sustained DPS, as well as faster fire alongside the LBX5s, for removing components. Of course, you can drop a ton of ammo to pick up a CAP:
I like it quite a bit. You definitely want a cAP when using ATMs from my experience, though. As LBX ammo looks plenty, there's an easy switch for 1 ton.
Fair point. So long as I have enough backup, I don't usually consider CAP necessary, but considering how much of the overall firepower the ATMs provide, it's definitely worth picking up. I'll add a CAP version to the OP.
