Hi,

I have a ca m15A4 and i am going to upgrade it too 400fps....
Besides the spring what other parts should i upgrade and why?
I already know i should upgrade the piston and piston head.
I also want too change the motor too somthing more powerful; i am considering either the hummer 1300s or a systema high grade motor but i dont know which one would be better for a 400 fps spring. Will Classic Army's gears be able too handle a new motor? Are there any parts you know of that will increase my guns overall performance?

Thank you! :cheers:
