PolarStar Kythera HPA Engine for Version 2 M4 Airsoft Rifles Add to Cart

• 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 translates into consistent nozzle movement and rapid follow up shots
• Adjustable trigger (weight, length of pull and over travel)
• Adjustable nozzle dwell/return speed
• Easy to install system that fits into a standard Version 2 gearbox as a single assembly and typically doesn't require any modification to the gearbox
• The Kythera has a wide operating pressure range of 60 psi to 180 psi which allows you to fine tune the velocity of the system and tailor for different requirements and applications
