    I want to put a full metal licensed on my ics m4s with the split gearbox and spring release in mind Is there a certain body I have to get?
    (also I'll have some engraving done on the bodies so I would like to know if that's a good idea or not)

    I don't own an ICS, but IIRC the ICS split GB will only fit in ICS bodies because it's a little wider then normal GBs.
