PolarStar Precision Airsoft Components (PPAC) was formed in January 2009 to fill the need for precision engineered airsoft upgrade parts. PPAC is a division of PolarStar Engineering & Machine (PSE&M), a unique blend of tenured American toolmakers and a full service CAE/CAD/CAM (Computer Aided Engineering, Design, and Manufacturing), special crafts machine shop keeping alive our proud manufacturing heritage of "Made in the USA".

Founded in 1997, PSE&M specializes in servicing the automotive racing industry by designing and engineering systems and components from "art to part." Whether a unique one off prototype up to and including manufacturing large quantities of finished and tested parts and assemblies. Operating under the auspices of the Delaware Association of Professional Engineers, we retain a Professional Engineer (P.E.) on staff to ensure and certify all design and engineering standards are met.

The JACK system was designed to answer the demand for an affordable, high performance HPA (High Pressure Air) 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.

JACK has only 1 moving part, the nozzle, which acts as its own poppet valve and is piloted by the solenoid. With the exception of the poppet being integral to the nozzle, the valve is similar to the poppet valve used in the previously released Fusion Engine and is what gives JACK its signature muzzle report. The system itself has only 6 parts and can be completely disassembled by hand in a matter of seconds so the system is very reliable and easy to maintain.

Just like all other PolarStar HPA conversions, JACK also allows for easy velocity adjustment. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 500fps with a .20g BB. This can be done simply by adjusting input pressure and poppet dwell to fine tune your rifles velocity in increments of just a few FPS at a time. Maximum velocity potential of the system will vary depending upon the barrels length and tightness of the bore. Longer and tighter barrels will yield a higher velocity while shorter or wider barrels will be yield a lower velocity.

As with all of PolarStar's electro-pneumatic conversion kits, you can quickly change and adjust key functions of JACK via the on-board FCU (Fire Control Unit) which is no bigger than an AEG's MOSFET and can easily fit inside of a rifles battery compartment along with a small Li-po battery. Using the FCU's five position joystick and LCD display you will be able to easily and precisely adjust such functions as the systems cyclic rate, fire modes and poppet dwell on the fly.

Although efficiency was not a critical requirement during development, JACK does boast some highly respectable figures in this category. This is made possible by is compact and intelligently laid out design which minimizes dead volume resulting in better air flow, faster response and less air used per shot. As a result JACK is considerably more air efficient than a bone stock Fusion Engine when operating in the same velocity range. Key Features
