Ics M4 body VS 1 piece mechbox
 

I would like to know if ics guns can suit a standard 1 piece mechbox like a systema complete kit?

That's actually a really good question. I have an ICS body as well, and if I could put a systema mech box inside of it, that would be awesome.

or will a ics split mech box fit in a different body.

I don't think doing it the other way around would work too well, as the meshing of the upper and lower on a mech box in say a TM body wouldn't become flush. But maybe... I hope someone figures this out. I'm gonna take one of my team mates guns and take out his mechbox, swap it with mine, and I'll try both ways for science!

good and come back with the answer !!
