ICS upper gearbox upgrade questions.

etd · May 27th, 2009, 16:51

Looking at mach1 I've found a complete and fairly cheap set to upgrade my upper gearbox with the ics split gearbox system. my main question is whats the difference between:

1) MC-71 Oversize cylinder (Full Capacity)

and

2) MC-58 Oversize cylinder (4 opening)

Do you own an ICS? those prices are for a full upper.

Full capacity is more for m16 length barrel and the ported is for m4 length.

M4 375mm barrel. split mechbox ics type is what I currently have. So don't bother getting the full? get the ported?

even easier. check airsoftparts.ca look at the modify cylinders. will show the proper porting for a range of inner barrel lengths.
