Polarstar is an American brand created in 2009 offering innovative air engineering solutions for airsoft. Its quality products made in the United States are designed by airsoft players for consistent improvement through community input.
The Fusion Engine is Polarstar's patented pneumatic system that runs on compressed air (HPA). It is installed in place of the motor and Gearbox of your AEG M4 type propeller. This system is fully compatible with your usual gun, hop-up block and magazines.
You will need to use an air cylinder with an HPA regulator for a range of 80 PSI. The Fusion Engine comes with a mini control computer (FCU) running on a 7.4v Lipo battery (not included).
This system will allow complete customization of your ride. From rate (up to 1800 BBs per minute) to firing mode to power, pre-set your rifle to achieve the performance you want. The Fusion Engine has a fully pneumatic operation, far more reliable and durable than a mechanical Gearbox. It is virtually maintenance free. This product is backed by Polarstar's 6 month warranty.
