AGM Airsoft Sturmgewehr StG 44 AEG 6mm BB Fullmetal, Realwood 0,5

Im selling my old Stg 44 Airsoft. 
I dont actually know what brand it is exactly but I guess it is AGM. 
Energy is 0,5 joule and both Semi-and Full Auto are available.
It is pretty old and I dont have a fitting battery so I cant really say how well it still works, but it defentily still shoots.
Other than that, and some scratches it is in pretty good condition!
Included are 3 Metal Highcaps (one is kinda unreliable), an original WW2 leather shoulderstrap, a original WW2 cleaning chain (stored in the Buttstock) and a reproduction of a Paratrooper-gunpouch for transportation.

Im open to offers :)
