Product Overview:

1. High-Performance HPA System – Built for Battle
The PolarStar JACK system transforms your standard G&G M4 AEG into a precision-tuned HPA-powered rifle. Using the same proven electro-pneumatic design found in PolarStar’s more expensive systems, the JACK delivers outstanding trigger response, adjustable FPS, and improved air efficiency—without the added bulk or weight of other HPA engines.

2. Drop-In Compatibility with G&G M4 AEG Gearboxes
This JACK engine is designed specifically for G&G M4 V2 gearboxes, ensuring a seamless drop-in installation. Whether you’re a skilled technician or a DIY enthusiast, installation is straightforward, allowing you to convert your AEG into a high-performance HPA rifle in no time.

3. Adjustable Velocity and Rate of Fire
Customize your gameplay with adjustable FPS (from 280 to 500+ FPS) and variable rate of fire using an external regulator and FCU (Fire Control Unit). The JACK engine allows for fine-tuned performance to match your field’s FPS limits or personal playstyle, from fast CQB bursts to long-range semi-auto precision.

4. Electro-Pneumatic Reliability with Minimal Wear
Unlike traditional gear-driven systems, the JACK uses fewer moving parts, reducing mechanical stress and wear. This not only increases reliability and reduces maintenance but also offers a smoother and quieter firing experience.

5. Consistent Shot-to-Shot Accuracy
Thanks to the JACK’s efficient single-solenoid design and precise air delivery, you’ll experience tighter shot groupings and consistent FPS, giving you a major advantage in long-range engagements and competition play.

6. Battery and Air Source Flexibility
The JACK is compatible with 7.4V and 11.1V LiPo batteries and works seamlessly with most common air tanks and regulators. This flexibility allows players to tailor their setup for weight, size, and performance on the fly.

Perfect for Competitive and Tactical Airsoft Players

Whether you’re entering competitive events, training for Milsim operations, or just want to dominate local skirmishes, the PolarStar JACK G&G M4 is built to deliver unmatched performance. Its versatile setup supports semi-auto, burst, and full-auto firing modes depending on your FCU programming, giving you total control over your airsoft weapon’s capabilities.
