This JACK is for Version 3 gearboxes if you are in need of a JACK that is compatible with Version 2 gearboxes CLICK HERE
The JACK™ system was designed to answer the demand for an affordable, high performance HPA conversion for AEG's. The system is a drop-in cylinder replacement that is universally compatible with a wide range of gearbox versions that have center-line nozzles.
Similar to its sister product, the F1, it replaces the original gearbox components with a programmable pneumatic system allowing for higher performance and greater reliability over a gear driven system. Although economically priced, JACK™ still retains the same performance and quality you have come to expect from PolarStar products.
SPECS
Velocity: 500FPS w/ .20g @ 120psi.
The Jack allows for easy velocity adjustment. Using a standard V3 as an example, velocity can be adjusted from below 100fps and up to approximately 500fps with a .20g BB. Longer barrels will increase the maximum FPS while shorter barrels will decrease it.
ROF: 30RPS+
The maximum cyclic rate of the Jack is affected by several factors, however, 30 rounds per second is a conservative number. Most configurations will exceed this easily.
Air Efficiency: 1200 shots from 13/3000 @ 1.5J (80PSI w/ .28g)
The JACK is extremely efficient. The patent pending design of the F1 allows for the most direct air path to the nozzle with minimum dead volume resulting in better flow, faster response and less air used per shot. Using a stock AK as a test platform, the JACK was able to fire approximately 1200 rounds for a 13ci/3000psi cylinder before pressure dropped below regulated output.
