Airsoft Canada - View Single Post - P90 shooting low FPS after spring upgrade

The thing that gets me is the stock spring is new only used during one game.
I have access to another brand new stock TM P90 that does shoot 270 FPS.
You would think its the Hop Up but have switch barrels back to the stock I get a 10FPS reduction..
