Just got a email back from fx usa and they said the new power plenum can not be ship to individual. Your gun must be send in to be install for $300. Not sure if that includes shipping but my guess is you will have to paid for shipping to them and back. Which in total gonna a be at least $400. They said it's due to safety issue. But most of us already know to how take our guns apart and fix them ourself. I wish they have a option for those who want to have fx install it for $300 plus shipping and another option for more experience users to just purchase the parts and install it yourself which would be a lot cheaper. What's your thoughts.
