regarding MP7 hi-cap mag
 

anyone has detailed pictures of the MP7's hi-cap.read from some database that it has capacity of 190,i just wonder the way it feeds BBs.
is that the same style as the MP7's low-cap,or same as the way those M4 hicaps feed BBs.(with a gearwheel at the bottom of the mag that used to feed BBs up to the chamber.
so can i have some detailed pictures from the bottom of that hicap?
thanks in advance.:)

All high caps use a wheel at the bottom to put tention on the spring, therefor feeding BB's. Only magazines without the wheel and Mid caps, Low caps, and Real caps.
