Spotted on Ruten.co.tw is the Classic Army M4 9mm SMG 100-Round Magazine with Adapter. As the name states, this allows you use a 9mm airsoft magazine with an M4 AEG. Some sellers have the CA M4/M16 100-round SMG Magazine but sometimes the adapter is hard to find. This package comes with both the magazine and adapter and feeds an M4 AEG, which should be Marui-compatible, well.
