PolarStar Jack Review

Jawsh takes a look at the new PolarStar Jack, giving an overview of it's capabilities and comparing it to the Valken V12 and the Polarstar Fusion Engine. Come grab one of these at our walk-in store. PolarStar Jack Description (Information from AirsoftJunkiez) Velocity: 500FPS w/ .20g @ 120psi. The Jack allows for easy velocity adjustment. Using a standard M4 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 extrememly 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 VFC M4 as a test platform, the JACK was able to fire approximately 1200 rounds for a 13ci/3000psi cylinder before pressure dropped below regulated output.
