So, I took apart my both my WE M4 and the PDW and made some comparisons between their brass tube systems. The M4's has a slightly longer brass tube (on both sides, where the inner barrel sits and where the nozzle assembly slides into) but this could easily be cut down. The problem lies in that the PDW's has a notch cut in the one side which keeps the entire system secured in the outer barrel. This notch could be added, but would have to be very precise since even the slightest difference would cause the magazine to not sit flush up against the brass tube (leading to all kinds of other problems).
I haven't decided yet if I want to attempt it. Anyone happen to have an old, unused closed bolt assembly that they could take some pictures and measurements of and post up?
