Where do you plan to use this in Canada?

I know this thread is ancient, I just wanted to add some detail in case it could help anybody in future.
I mistyped in my earlier post, there is only the M120, there was never an M130.
( all fps are with .20g bb's )
A friends gun I upgraded with the same M120 spiring ( ICS MP5 ) shoots 400-410 fps with an M120. It is very consistent, and the stock ICS moter has no trouble pulling it back with a large type 8.4v battery. That didn't seem excessive from what we have read. I've read some fields cut off at 350, and some at 400. Not that there is a field in the state i live in, but safety first.
My CA G36C currently has a 9.6v large type battery, and it still would not consistently fire with the M120 spring it. So I cut a few coils off ( 3-4 ) of that spring. It now chronos at 340-360 fps. I also installed a CA "bore-up" kit which consists of a new piston head and cylinder. So that should also slightly affect FPS. I mainly ordered it because if I was going to break apart my mech box to try that M120 spring again, even if I failed and ended up using the stock spring I wanted to have have accomplished something!
And as far as where in Canada? Well, no where near Canada! I just re-read the thread and I must have edited out that part where I graciously ask for help from this active and vibrant community despite not being in Canada. I very much appreciate the responses.
