WE actually designated it as the 4168 but we all know that it is based on the HK416 assault rifle. This is the open bolt/chamber version which is now at eHobby Asia for US$289.00 and the improved features are the steel made nozzle and dual O-ring sealing. With the exception of the stock, most of the rifle is made of metal. It does not come with HK trades for those who prefer the HK mark on it.
