  • Designed from the ground up as a high performance mechanical HPA system, not a modification of a solenoid operated design
  • Patent pending valve mechanism provides excellent efficiency and consistent velocity combined with a realistic trigger pull and reset
  • Completes a full shot cycle on the trigger alone which translate into consistent nozzle movement and rapid follow up shots
  • Adjustable trigger (weight, length of pull, and over travel)
  • Adjustable nozzle dwell and return speed
  • Easy to install system that fits into a standard Version 3 gearbox as a single assembly and typically doesn't require any modification to the gearbox
  • The Kythera has wide operating pressure range of 60 psi to 180 psi which allows you to fine tune the velocity of the system and tailored for different requirements and applications
