This airsoft requires a machined carbon fiber pipe.
You can either machine it yourself or use a cutting service near you.
The engine is recommended to be a reaper due to simplified wiring and the fact that full is not implemented.
Inferno can also be used, but requires a universal kit or premium board.
Some 3d printed parts require welding as shown in the accompanying photos.
They also need to be sanded to ensure smooth assembly.
