The PolarStar Silver Ver.2 Fusion Engine offers all the same performance and reliability of the original fusion engine but comes pre-upgraded with with a red low flow poppet for increased efficiency and stability. Also included in the pre-upgraded Ver.2 Fusion Engine is the Black M4 nozzle giving the user an FPS of 425 to 475 FPS depending on barrel length and PSI.
The PolarStar M4 Fusion Engine takes place of any Ver.2 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 on-board computer known as the Fire Control Unit (FCU). This kit comes with the necessary core parts to convert your AEG to the Fusion Engine system. HPA stabilizer and tank required but not included.

HPA Tanks are a safe and effective source of power though there are some precautions you must follow. Please follow these proper precautions when using HPA systems:
- NEVER put oil in the fill valve of the tank, or else the tank can combust on refill and serious injury can occur. Lubrication is not necessary in HPA systems.
- ONLY allow properly trained professionals to fill your HPA tank.
- ALWAYS double check your Regulator pressure. Never raise the regulated pressure above 120 PSI.
- Make sure to have your tank Hydro-Tested when necessary (Usually 3-5 years from date marked on tank, depending on make and model).
- Be sure to properly transport your HPA tank. Store in a safe, secured place when in a vehicle, and be sure to stow in a bag or tank cover when in use. Avoid dropping the tank on hard surfaces as this can seriously damage the tank and lead to failure.
- Always turn off the tank and bleed the air line when you are done. This will ensure a longer tank and system lifespan.
