Weapon Mods/Plans

Hey guys,

my all time favourite weapon at the moment is the gatling plasma. my build focuses around a bit of stealth and rifles, and big guns and tanking for the multiplayer events.

I'm looking for gatling laser plans, aswell as mods for it (as I've only ever come across one) and plans for the gatling laser, plasma rifle and gauss rifle (and mods too)

Can anyone help?
