Neo035 reviews to airsoft versions that are used by reenactors and some by collectors, the AGM MP40 and SHOEI MP38. Both used in World War II by Nazi Germany, at first glance they look the same but there actually some differences such as the MP38 38 receiver was made of machined steel but producing it was a time-consuming and expensive process whilst the MP40 receiver used stamped steel and electro-spot welding was done as much as possible.
