Ok, I am peeling the onion here in an ICS m4 I am fixing for a friend. This has turnied into a nightmare.

This is the split gearbox.

For starters this is a classic. "souped up" gun and to be honest all I am doing it trying to put it back to the original state.

There are so many parts on this this that were "supposidly" compatable its not funny.

For example I found the nozzle you need on the ICS is ICS SPECIFIC. YA, it is!

Most M4 nozzles are too long and partially block the chamber where the bbs feed. I even went to an ICS dealer and he too saw this and agreed.

Anyway, I am now shopping for the matching ICS bucking as its shooting with minimal force. (piston and nozzle are fully back to stock and full compression so this is the only area of issue left)


That said, I am fully aware the hop up chamber and the gearbox need to be butted up against each other for a tight seal. (MACIEK did an awesome posting on this issue recently)


So as I close the window on this shit show, my question is do the ICS have a mag that is for this gun only?

I am now wondering if the standard plain jane mag, or p mag, might not have the correct spacing and be forcing the hop up slightly away from the gear box loosing compression?

Is this a stretch?

What is the TRUE difference between a standard M4 mag and Toyo mauri (which is recommened for the gun)

?
