Will a new spring increase fps? I'm thinking of getting a PDI 120% for this summer, then I will probably upgrade to a systama m100 or 110 for next summer. Are springs hard to install? I have no experience modding airsoft guns and I'm hoping it's fairly easy to do.
Also, would I have to buy a new charger when I get a new batter?And just to make sure I'm not mistaken, this battery would wourk fine in a kraken right? http://velocityarms.ca/index.php?mai...roducts_id=188
