This VFC Avalon PDW has a polarstar jack installed along with an IGL connection.
The Avalon Series is the latest generation of next level AEGs from VegaForce Company (VFC) meant to allow the shooter to compete at the absolute highest level. Numerous enhancements have gone into the Avalon series that puts them in a league of their own. Notable improvements inside and out include an Elite Force flat-faced blade trigger, VFC QRS enhanced modular stock and textured pistol grip, VFC QRS trigger finger rest (a first in the industry), Avalon custom gearbox, CNC aluminum handguard, and a 120-round updated QRS mid-cap magazine.
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.
Velocity: 500FPS w/ .20g @ 120psi.
The Jack allows for easy velocity adjustment. Using a standard V2 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.
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 M as a test platform, the JACK was able to fire approximately 1200 rounds for a 13ci/3000psi cylinder before pressure dropped below regulated output.
