I want a G18c under the FPS of 330 with .20 gram. If it is any higher I can't use it at my arena. Will the new KWA ATP shoot under 330 with a downgrade? If so what is it. Should I go with the WE? It guarantees a low FPS but no reliability consistent as I would like. My last option, the hard to find KCS G18c. I need real help.
