"PolarStar is truly the most advanced, state-of-the-art, on-point performance in Airsoft today. I've built several PolarStars, mainly in VFC and G&P bodies, and they perform amazingly well.
What's great about PolarStar: (1) smooth, instantaneous (and incredibly satisfying) trigger response; (2) control and adjustability via the Fire Control Unit; (4) no maintenance, no hassles, ... simple and easy to use; and (4) USA made. I've actually been to the facility in Delaware where they are built, and the guys who make them are really excellent people. It's as immaculate a factory as one could imagine - they excel at fabricating high-precision metal parts.
I've been through the gamut of other types of Airsoft guns, first GBBR then AEG, and PolarStar is clearly the best overall experience. Between the unit itself, the tank, the air line, etc., it more expensive, but as others have said, P* is worth every penny! "If you're looking to buy this, definitely do! It is the most reliable system for airsoft I have used and this Gearbox will fit is almost ANY AEG M4. Please note: when you buy this it does not come with a regulator, a QD (Quick Disconnect) Male connector), a tank, or a small LiPo battery. It does need the battery, just in case you were wondering.
Easy to install
You can still use Mid-caps and Hi-Caps
Controllable FPS and RoF (With Air adjustment.)
Extremely accurate (Even with a stock barrel)
The price (But its worth every penny)
Selector plate needs to be modified for a G&G lower. "This is THE most amazing gearbox. Read More Reviews Write a Review

PolarStar Airsoft V2 Gen3 Fusion Engine Electro-Pneumatic Gearbox Kit
The PolarStar Gen3 V2 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 onboard computer known as the Fire Control Unit (FCU). This kit comes with the necessary core parts to convert your AEG M4 / M16 to the Fusion System, and can be used with other Ver 2 Airsoft AEGs by replacing the selector plate, trigger and Fusion Engine nozzle (additional FE nozzles, triggers and selector plates not included). 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. A great thing about the Fusion Engine is that stripped gears, blown motors, fried batteries, and just about every other problem with AEG's no longer exist. Say goodbye to hundreds of dollars on maintenance and countless hours fixing your gun!

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.
