HPA Conversion Kit JACK™ V2 for M4/M16 - PolarStar

Product: HPA Conversion Kit JACK™ V2 for M4/M16 - PolarStar Product description: JACK™ V2, also known as "Simple Jack," is designed for users looking for an affordable and high-performance HPA conversion for AEGs. This system replaces the interchangeable cylinder and is universally compatible with gearboxes with center-axis nozzles. JACK™ replaces the original mechanical components of the gearbox with a programmable pneumatic system that offers higher performance and reliability than traditional mechanical transmissions. JACK™ features a single moving part, a nozzle that functions as a poppet valve. A solenoid drives the nozzle to open the air flow, allowing for higher air flow into the barrel compared to systems that use a solenoid as an opening valve. Technical Specifications: - Velocity: 500 fps with 0.20g BBs at 130 psi. Velocity can be easily adjusted by changing the input pressure, without the need to replace nozzles. For a standard M4, velocity can be set from 280 fps to 500 fps with 0.20g BBs. Longer barrels can increase maximum velocity, while shorter barrels can decrease it. - Rate of fire (ROF): Up to 30 rounds per second, affected by operating pressure and the quality of the magazine and BBs. - Air efficiency: Over 1,000 shots from a 13/3000 bottle at 1.5 J with 0.28g BBs. The design minimizes empty air volume, improving range, response speed, and reducing air consumption per shot. Tested with a 6.05 mm barrel length of 365 mm. JACK™ maintains the high performance and quality that are standard for PolarStar products and offers an effective solution for users looking for a reliable HPA conversion.
