What do you think?

[Kraftmatik]

I'm upgrading my internals in my MP5A5 all stock to a devil aluminum piston head, the modify polycarbonate piston and the modify s130 aeg upgrade spring. This is what I'm thinking....will it work though? Or will I order it only to find that it's all wrong. Do I or will I need anything else? Like a gear upgrade or anything? Please comment and tell me what you think if you have experience in this sort of thing please. I need input.:banghead:

spring is too stiff. I'd stick to 110 for modify brand, 120 actually goes upwards of 400, sometimes even 440. s130 will put you at about 440 at the very least. Everything else is good.

(In all honesty I don't like modify springs, I'd say use ARS cratus or Prometheus)

Madbull M120 is like a Prom MS130. and M110 is like an MS120 and M100 is like an MS120.

Aluminum piston head? Go polycarb modify head.
