The PolarStar M249 Fusion Engine takes place of any M249 AEG Gearbox as a direct drop-in. It is powered via a High Pressure Air (HPA) setup and only requires a small battery (7.4v-9.6v NiMH or Lipo recommended) to power the onboard computer known as the Fire Control Unit (FCU). This kit comes with the necessary core parts to convert your M249 to the Fusion System. HPA stabilizer and tank required but not included.

The Fusion Engine is completely adjustable via the FCU and by varying the pressure from the HPA system (90-120 PSI). The Fusion Engine Kit comes equipped with PolarStar's Blue Nozzle (FPS listed below). Optional Color-coded nozzles are available to be able to move the Maximum FPS Range up or down.

The Fusion Engine is compatible with AEG style Hopups and Inner Barrels allowing the use of standard upgrade parts.
