Need help picking the right SystemA mechbox.

[moto]

I have a CA M15A4 CQB. I am going to change the barrels so that I can run a 500-550mm inner barrel. I am looking for the proper SystemA complete mechbox that will fit my AEG sniper setup. Ive decided on the 150 spring mechbox.. problem is.. Im not exactly sure which is compatable with my reciever as SystemA is listed by TM models.. not CA.

1. What TM gun is my gun compatable with as far as the mechbox goes?

2. Wiring & batteries: I have the crane stock w\ 9.6v large battery. Is this going to be enough to power this setup... semi-auto only? I dont mind running a different stock and battery setup if I have to.

3. Im pretty sure I'll also need a new motor. Im thinking the SystemA Magnum. Your thoughts?

4. Any other helpful comments or suggestions would be appreciated.

Thanks much.

You will need to rewire the mechbox yourself for your crane stock.

Yes, your battery is enough to power this setup - it SHOULD have a proper torque up gear set installed.

You don't NEED a new motor, but if you get one, the Systema magnum isn't a bad choice. Neither is an Eagle Force Hummer 1300L.
