- HPA powered from Airsoft/Paintball tank+regulator or compressor, from 40 to 80 PSI (shown running at 50 PSI)
- 3S Lipo for the solenoid and fire control group
- Arduino fire control group (regulates the dwell-time of the piston and the cooldown between shots to ensure maximum FPS and trigger response.)
- Fire selector (Safe-Semi-Full at 300 RPS)

- Bullpup configuration and short OAL
- Mostly 3D-printed, with machined sideplates.
