There's SEVERAL different grades of material. I don't have a tonne of ICS experience, but I seem to recall something about their M4 metal bodies not being to aftermarket spec.
That is very true. ICS can get very annoying when replacing parts or even adding accessories on it (ex: sling backplate, tappet plates, hop up, etc) as many of the guns is specced for their own parts/replacement. And if you want to use aftermarket parts you'd have to do quite a bit of modding.
