Madbull spring
I'm have a KWA S-System and it shoots like 430 fp with .2 bb's and 360ish with .25. Obviously something is wrong with it but I'm not sure what it is. So I am just going to change the spring out for a new one. I want to get a MadBull M110 but it's not on the spring chart, so I am going to assume that it wll put the fps at bout 380-390 with .2. Am I right in assuming this?
