these are the complete collection of light and rotary autocannons I have made. Making them range reasonbly without making them defunct on arrival was something I was having a tricky time in making. I hope I got close enough to what they'd actually be. these would most likel be FedSun/FedCom inventions intiially before becoming common. these are first draft Statblock(s).
Light UACs: lighter, shorter ranged UAC's.
Light LB-X-ACs: Lighter, Shorter Ranged LBX's.

So there you have it, my Light LBX,UAC,LAC10 and RAC10 all in one thread. I if you want to playtest them that's fine, feel free to give me feedback on how they perform in practice and I'll see about calculating BV estimated in the future.
