This full metal constructed AEG equipped with VIS integrated receiver and rail platform. The VIS upper receiver assembly ties the normally individual receiver and front rail into an aggregate single part which overcomes many problems that are associated with the traditional "Two Pieces" design. Each rifle comes with a unique serial number and detailed laser markings engraved on the integrated receiver and rail platform. The gearbox is made from high quality internal parts to ensure the shooting power and durability. Package comes with 300 rounds magazine, a vertical tac grip, two cheek weld adaptors and a barrel nut tool.
