What magazines can I use in my ICS MP5A5?

[Jacob Wright]

Hi,

I've recently got myself an ICS full metal MP5A5. It came with 2 230rd mags, but I want more. I prefer mil-sim gaming so I'm more into real-caps. The only problem is, I can't find any ICS real-cap mags anywhere. So it would be a real help if you could post back with compatible mags or where I can get ICS ones from.

Thanks,

J
