Polarstar Fusion Arcturus AK

The ak body is a a Arcturus mod1 and the engine inside the gun is a discontinued polarstar V3 Fusion engine the gun is worth about 700 brand new and the gun is in really solid shape externally and looks new I still have the AEG gear box aswell that I’ll send with it if requested for no extra price I’m looking to trade this gun aswell and seeing as this engine is rather hard to find since it’s discontinued
