Scylla HPA - V2 offers everything your HPA gun needs – in one compact and powerful solution.

Scylla HPA - V2 replaces the control unit and trigger board and is compatible with the following HPA systems:
- PolarStar F2
- PolarStar F1
- PolarStar JACK
- Wolverine Inferno Gen 2
- Other systems controlled by 5V electro-pneumatic solenoids (single and dual solenoid), close-bolt and open-bolt
The combination of optical and magnetic sensors ensures greater trigger sensitivity, better response and high durability during use.
The magnetic trigger adapter allows for quick and precise sensitivity adjustment directly within the app – without complicated tuning.
Free app
Thanks to built-in wireless communication, you can easily configure everything in the mobile app (iOS and Android), and it’s available entirely in Czech.
Scylla offers everything you’d expect from a modern HPA unit:
- Solenoid settings
- Binary trigger
- Burst fire
- Trigger sensitivity
- Rate of fire control
- Firing statistics
- And much more
Customisation
- Saving and quick loading of profiles (e.g. CQB, DMR, various joules)
- Individual firing modes for the SEMI and AUTO switch positions
- Option for different solenoid settings for SEMI and AUTO firing modes – reduced muzzle velocity for close-quarters combat
- Copying the shot counter from the original system
- Technical lock – an accessory designed to prevent unauthorised use or unintended changes
- External output port for connecting custom accessories such as a lighting system for the BBs in the hop-up chamber
All changes take place in real time – you can see the difference immediately whilst shooting.
Easy installation into the mech box – fully integrated inside the mech box in place of the original switch contacts.
You receive new features and updates free of charge via online updates.
Extremely low power consumption – just 1.5 mA, ensuring maximum energy savings when idle. We recommend using a 7.4V Li-Pol battery.
