How can I lower the FPS on my KWA LM4?

Just a quick question. Would prefer to keep using Green Gas if possible. Need the FPS to be lower than 350 :/

Thanks to whoever helps

Use NPAS

Send a link to a good one that will fit the KWA LM4?

why stick with green gas? I take Abbey 144a, Abbey Predator Ultra and WE green gas with me when using my G5, we chrono every gun before start of play so means if the green gas is a little hot I can use the others to suit. Saves modding a gun that is working fine as is :-)
