and this kit was discountined
but they have this kit
http://www.redwolfairsoft.com/redwol...l?prodID=20438

maybe more easy to change the spring to change fps depending where you play... (like systema gun)
who can said me if i'm have understand the function of the kit...
and if I need more parts to complete this gearbox (because isn't clear on the page)
