crazyNCman digs the round hanguard of the ICS MP5SD which he says makes it easier to put in a battery and he explains it nicely that the design of the frontend of this AEG is based on the integrated receiver from the real steel one. And if prefer your MP5 to have a folding stock, this version does come with it. Good thing the battery compartment is empty when he removed the handguard with the magazine still inserted.
