Most gas airsoft guns do strip down like their real steel brothers. My Licenced Uramex H&K MP7 strips down the same way the real MP7 strips down. Quickrelease the sliding stock and remove 2 body pins in the back which releases the bolt assembly, charging handle, and firing pin. Only difference is mine has a reinforced polycarbonate loading nozzle rather then a chamber.
Oh, and good luck trying to reinstall the trigger if you decide to disassemble it. H&K didn't make that so user friendly.
