Code Name "Simple Jack"

The JACK™ 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. PolarStar Filter Fitting now included!

Similar to its sister products, the JACK™ 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, the JACK™ still retains the same performance and quality you have come to expect from PolarStar products.

The JACK™ has only one moving part, the nozzle, which acts as its own poppet valve. Similar to the Fusion Engine™ and F2™ poppet, the nozzle is only piloted by the solenoid to open air flow through the poppet with none of the firing air coming from the solenoid itself. This design lets the JACK™ send a higher flow of air down the barrel than systems that only use a solenoid as the firing valve.

Gel Ball Compatible

JACK HPA conversion kits can also be configured for use in gel ball systems.

Please contact us for information on ordering JACK systems for gel ball use.

Velocity: 500fps w/ .20g @ 130psi
The JACK™ allows for easy velocity adjustment by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 500fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum velocity while shorter barrels will decrease it. 
ROF: 30rps
The maximum cyclic rate of the JACK™ is affected by several factors such as the operating pressure as well as quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations.
Air Efficiency: 1000+ shots from 13/3000 @ 1.5J  w/ .28g
Although not a critical requirement during development, JACK™ does boast some highly respectable figures in this category. This is made possible by its intelligently laid out design which minimizes dead volume resulting in better air flow, faster response and less air used per shot.
(Test Configuration: 6.05x375mm Barrel)

A must have for superior sun protection!
Size: 6.7 Fl Oz (Pack of 1), Size: 6.7 Fl Oz (Pack of 1)
Neutrogena Beach Defense SPF 50 is an absolute game-changer when it comes to sun protection. Whether you're relaxing at the beach, swimming, or enjoying an outdoor adventure, this sunscreen provides broad-spectrum protection that effectively shields the skin from harmful UVA and UVB rays. One of its standout features is its lightweight texture, it glides effortlessly onto the skin without feeling greasy or heavy. Unlike some sunscreens that leave a sticky residue, Beach Defense absorbs quickly and smoothly, making it ideal for both face and body application. Another major plus? Water resistance! This formula stays put, even after swimming or sweating, ensuring continuous protection throughout the day. And despite its strong defense against the sun, it feels refreshing and comfortable on the skin, making reapplication a breeze. I used it during a vacation in the Dominican Republic, and me and my family enjoyed it. My 5 years old girl has been protected from the sun all the time. If you're looking for reliable, effective, and easy-to-use sun protection, this sunscreen is an excellent choice. Highly recommended! ☀️👌

Great for Kids, Smells Nice, and No Harsh Chemicals
Size: 5 Ounce (Pack of 2)
This sunscreen spray is easy to apply, not greasy, and doesn’t leave a sticky residue. The tropical fruit scent is light and pleasant, which makes it easier to convince kids to wear it. I also like that Alba Botanica avoids oxybenzone and other harsh chemicals. It holds up well for swimming and outdoor play. The 2-pack is convenient to keep one at home and one in the beach bag. It is a great deal!
