WTT Riven mod for another

[Sanxws]

Hello Tenno,

i want to trade My Vulklok (damage to grineer, damage to infested, fire rate) Riven Mod for another. I don't care the stats, but I would have a mod for one of these weapons:

Amprex, Braton, Boltor, Paris, Dread, Opticor, Supra, Soma, Gorgon, Lanka, Vectis, Latron, Rubico, Cernos, Penta, Zarr, Simulor and Grakata.

I am quite desperate because my negative luck won't give me any other Riven mod in Sorties and I really want to experience this new system, so please answer me rapidly.

thank you by advance.
