I would NOT use a "magic" pin, expanding type receiver pin...although that's what they're great at doing, I don't think that the airsoft rifle materials are up to the stress while in use (i.e. it'll be nice and tight...then probably pop the front lug of the upper receiver after shooting).
Mine has no play when assembled, but a bit of play when field stripped. If there was a bit of play I'd probably go with a shim ring and try to keep them even between both sides of the front lug.
