What's Included? 1 x Kythera Engine Features: 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 pull alone which translates into consistent nozzle movement and rapid follow up shots Adjustable trigger. Adjustments include: Weight, length of pull and over travel Adjustable nozzle dwell/return speed Wide operating pressure range of 60 to 180psi Technical Specifications: Model Number: 10000774 Operating Pressure: 60psi - 180psi Velocity Ranges: 270fps - 500fps (measured using .20g 6mm BBs 6.05 ID x 380mm L barrel) Fire Modes: Semi-Automatic Q A Q: What makes the PolarStar Kythera V2 unique? A: The Kythera is a fully mechanical HPA system, requiring no electronics or batteries. It offers a realistic single-action firearm trigger feel, excellent efficiency, and waterproof operation. Q: How does the Kythera complete its shot cycle? A: The system completes a full shot cycle on the trigger pull, automatically chambering the next round and refilling the firing volume. This enables rapid follow-up shots and reduces double feeding. Q: What is the operating pressure and velocity range? A: It operates at 60-180psi, providing velocities from 270fps to 500fps with .20g BBs. This makes it versatile for CQB, field, or sniper roles. Q: Is the Kythera easy to install? A: Yes, it installs as a single assembly into a standard V2 gearbox with no major modifications, retaining only the trigger, spring guide, selector, and safety components. Q: What sets the Kythera’s trigger apart? A: The trigger replicates the feel of a real single-action firearm, with adjustable weight, length of pull, and over-travel. It delivers a crisp break and realistic reset. About the PolarStar Kythera: The **PolarStar Kythera V2** is a groundbreaking mechanical HPA sy
