With perfect air seal a 120 spring will net you between 420-440fps so yes, it's definitely way too low.

*edit* Also, worn and damaged buckings will caused air loss between the hop up assembly and the nozzle, resulting in crazy FPS drops.
thanks, do you have any recommendations on a bucking? I hope I can get it through amazon.ca or .com I looked through some airsoft stores here and they barely stock buckings...
