The Perun V2 Hybrid is designed for Tokyo Marui standard V2 gearboxes. While it fits many brands (Specna Arms, G&P, ICS), some shells like G&G G2 or Cyma may require modification. It is incompatible with KWA ERG, Ares EFCS, and Classic Army ECS systems.
Selector calibration is recommended after installation. Enter Sensor Check/Calibration mode (usually by holding the trigger during startup) and follow the specific manual instructions for your model (V2/V3) to register safe, semi, and auto positions.
