Very interesting build. I might try to squeeze a ton to get UAC5 or swap down to UAC2 but either way it looks fun
Unfortunately UAC5 also occupy +1 slots compared to AC5, so you can't fit it unless you downgrade to light ferro-fibrous and/or downgrade/remove something else, which is really unfortunate. Fitting a UAC2 is interesting and you can even add +1 ton of ammo, but I personally dislike the AC2 due to the lack of pinpoint damage, especially at range. AC5 couples well with LPPC for both bullet speed and range, that's why I chose it.
4/5, 4 kills first time out with the AC5 variant. Better than I expected ;} EDIT: AC2 doesn't hit hard enough to justify the downgrade.
