Polarstar is an American brand created in 2009 offering innovative pneumatic engineering solutions for airsoft. The Fusion Engine is a patented pneumatic system that uses compressed air (HPA) and is installed in place of the motor and Gearbox of your AEG replica. It is installed in place of the motor and Gearbox of your AEG M4 replica. This system is fully compatible with your usual barrel, hop-up block and magazines.
You will need to use an air cylinder with an HPA regulator for a range of use from 80 to 120 PSI. The Fusion Engine comes with a mini control computer (FCU) running on a 7.4v Lipo battery (not supplied). This system will allow complete customisation of your replica. From the rate of fire (up to 1800 BBs per minute) to the firing mode and power, you can carefully set your replica to achieve the performance you desire.
The Fusion Engine is fully pneumatically operated, making it much more reliable and durable than a mechanical Gearbox. It requires almost no maintenance.
This product is guaranteed for 6 months by Polarstar.
