Upgrading/ fiddling with an MC51??

[jockjay]

Hey guys, just a few questions about the above:

Im getting a TM mc51 with solid stock, things i want to do to it-

Which mags (METAL MIDCAP ONES) are the most reliable?

is the sliding stock the same as the MP5 one as i cant find an 'mc51' one?

By putting a slider on and re-wiring battery to the front can i still fit a mini in a ront ris kit or am i going to go the PEQ or lipo route?

Any help greatly appreciated!!

Thanks for looking,

Jay.
