The Polar Star JACK is one of the easiest conversion options for turning any V2 M4/M16 style into one of the best performing airsoft guns on the field. The drop-in JACK cylinder replaces the cylinder assembly in most V2 center-line nozzle gearboxes. When connected to an HPA line, the JACK performs similarly to the Polar Star F1 in that it the pneumatic system is tunable for a wide range of rate of fire. Compared to the vast amount of moving parts in a classic gearbox, the JACK has only 1 moving part, the Air Nozzle, exponentially increasing the reliability vs. classic gear-driven AEGs. HPA provides instant trigger response even compared to typical AEGs using 11.1v LiPO batteries.
