If you like this gun with the stock mag, get a CO2 mag. It's a whole different game then.
On a warm day, I've chrono'd the WE's on CO2 at over 400 fps, and they kick like a mule as well.
But, I'm not so sure that Marui mags will run that well with the heavy slide of the WE. I had one and the Marui just couldn't sustain a full mag worth of shots. The WE mags dump alot of gas, and suffer pretty good cool-down, just like other mags that use high-flow valves.
I've found in the past that the QC on finishing with the WE left something to be desired, but they used to be real cheap. My favorite one was the AE 5.1 Striker, but they don't make that one anymore.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
