PolarStar - Kythera V2 HPA Mechanical Engine

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 nozzle dwell/return speed. Wide operating pressure range of 60 to 180psi.
