I am selling the whole HPA EVO kit with everything included in the original packaging, and also a 3D printed HPA grip for free.
HPA engine was tested at home, but never used in game.
The contents are:
Wolverine Inferno GEN2 engine
Spartan Electronics ECU board
Filter hose for pistol grip
ASG Ultimate 70° hop-up rubber for HPA
Hop-up nub
O-ring replacement set
ECU support tube
Stock lock set (button, spring, sleeve)
3D printed grip with screws.
The last picture is just for reference how the grip looks, the gun will not be included.
