VS Airsoft Component question
 

I am ordering a replacement gun unit for my VS M1 Abrahams so that it will be airsoft instead of IR. Does anyone know what FET(transistor) is used for the power to the gun? It is the one that is mounted by all of the wires on the board. I don't want to spend an extra $40 right now(bill week) for a replacement board for in the tank. I allready see where everything is wired to the board(thankfully they are all labeled). Any help here will be greatly appreciated. Thanks in advance.
