Polarstar fusion engine

The original HPA conversion. Unmatched performance and adjustability in a complete gearbox replacement. Designed to answer the demands of today's hardcore airsoft player, the patented Fusion Engine is one of the most reliable, high performance airsoft systems available today. No matter if you need a high fire rate CQB setup or a high velocity sniper platform, the Fusion Engine can do it all without sacrificing dependability or trigger response.

Constructed from CNC machined aluminum our system is extremely durable and is even capable of operating under extreme temperatures without decreased performance or reliability. Using the FCU's five position joystick and LCD display you will be able to easily adjust such functions as the systems cyclic rate, fire modes and nozzle timing on the fly.

With the Fusion Engine in your rifle you will also be able to adjust its muzzle velocity via the remote air rig sold separately. Adjusting the PSI output on your air rig will allow you to fine tune your rifles muzzle velocity so you will always be able to get it exactly where you want it.

And then for larger velocity changes we offer a series of air nozzles with varying bore sizes to shift the velocity adjustment range up or down to best meet your requirements. The best part is that our system is extremely user friendly. Even if you have only the basic understanding of an airsoft rifle, you will find that operating and manipulating this system is very simple and does not require a degree in airsoft engineering to figure out.

These allow the Fusion Engine to be installed in a wide variety of replicas. In addition to accessories made by PolarStar there are a number of aftermarket parts for the Fusion Engine. These include airlines, poppet shim kits, Quick Exhaust Valves.

With the introduction of the GEN3, now you can! This makes it possible to adapt the engine for use in multiple rifle models which share the Version 2 gearbox without any major modification. However, by installing a different nozzle or rifle specific conversion kit, you will be able to expand the number of rifles it will be compatible with.

The internal operation of the GEN3 FEV2 and the GEN2 FEV2 cylinder assembly are exactly the same and share many of the same parts, so it offers the same stellar downrange performance and rock solid reliability as its predecessor.

This GEN3 does however feature a new side plate design to accommodate the AEG selector plate and is equipped with a new electronic switchboard. One advantage to this new design is that the switchboard offers a wider contact point with the selector plate to allow for varying tolerances in the rifles selector assembly making for improved out-of-the-box compatibility with an increased number of rifle brands.

This feature enables the user to install an optional 90 degree fitting inside of their engine allowing the air line to be routed to the rear of the engine and exit through the buffer tube sling plate on an M4 series rifle.

Quantity: Decrease Quantity: Increase Quantity:.Here you will find the answers to the most commonly asked questions regarding our systems and HPA in general to help you get started in the world of HPA airsoft.

We currently offer two different lines of HPA conversion systems. So, you just remove the whole gearbox and drop the Fusion Engine into the rifle in its place. Then we also have our line of cylinder conversion kits which are cylinder replacement systems for an AEG's gearbox. These reuse the original gearbox shell and simply replace the gearbox's internal components.

No, our systems are designed to work with the AEG's original barrel, hop-up and magazines so nothing needs to be changed. Three different components are needed to run our systems. All of our systems require minimal maintenance as each system only has at most 2 moving parts. We recommend disassembling, cleaning and greasing each system after every 30, to 50, shots.

Dual solenoid systems use two solenoids to move the nozzle and fire the round. This allows each action to be controlled separately and precisely. Single solenoid systems have only one solenoid, which controls nozzle movement from it's retracted idle position to the forward firing position.

The firing air is not directly controlled by the solenoid, but by the position of the nozzle as it moves forward to chamber the round.

It is the most adjustable system of the group with the widest range of adjustment in both velocity and rate of fire. It is a dual solenoid, closed bolt system so you are able to adjust the poppet valve firing air and nozzle feeding independently for unparalleled control over both the loading time and air volume used.

Being a true closed bolt system it is easier to achieve a high level of accuracy since it is not as critical of the hop-up configuration as an open bolt system. Additionally, it does have the best feeling trigger since the trigger micro switch is custom fit to the frame so the trigger has a distinct break, hard stop and short reset. Like the Fusion Engine, it is a dual solenoid, closed bolt system for complete independent control over the poppet and nozzle and delivers the performance you can only get from a closed bolt system.

It is the most air efficient and uses a flow regulating check valve as well as "2-stage" firing. The unique flow control system uses an integral check valve to regulate the forward speed of the nozzle while maintaining the fastest retract speed possible.

When the nozzle is traveling in the forward direction the check valve is sealed, limiting the speed of the nozzle for smoother chambering and consistent BB placement. After the nozzle travels a certain distance, it begins to allow airflow through the bore to begin the acceleration of the BB.

When the nozzle reaches the forward position the check valve opens to allow the maximum flow into the barrel. The additional flow is maintained throughout the rearward travel of the nozzle, allowing it to retract without limiting its rearward speed.

In addition to the flow control and 2-stage firing, F1 also uses a custom solenoid designed specifically for this application. This allows the solenoid to become an integral part of the system rather than just a switch to control airflow. The advantages include a more compact system and a more efficient system due to the reduced internal "Dead Volume". It has a simple, straight forward design which is very reliable and delivers solid performance.

It has better air efficiency than a stock Fusion Engine and is only slightly less air efficient as an F1. Basically the way the system comes as stock, the poppet valve allows the maximum amount of air flow through the system and it is the nozzle which restricts the flow into the barrel which varies the velocity.

This gives you a wide range of velocity adjustment by simply changing out the nozzle to shift the velocity range of your rifle up or down in large increments.

The low flow poppet valve does what the name suggests and restricts flow at the valve itself so it allows less air through.

Therefore the main restriction is back further in the system instead of right up front at the nozzle. Normally, with the nozzle being the restricting point, there is air backed up in the section between the poppet and the nozzle which will only be able to vent out as fast as the nozzle's restriction allows.

If a more restrictive nozzle is needed to keep the muzzle velocity within field limits, there will still be air pressurized in this section after the poppet valve has closed and the BB has left the barrel so that air is wasted. Since it is the poppet valve which turns the air flow on and off, having it being the restricting point conserves air since less air is allowed through at once.

The low flow poppet also helps improve how smoothly air flows down the barrel since it has time to expand slightly in the system after it goes through the valve so there is less turbulence behind the round which can improve accuracy slightly.It can be frustrating to purchase upgrades only to find out that they don't fit your particular rifle.

To make things easier we have compiled a database of information on compatibility of the various PolarStar HPA conversions into a wide range of models. Over the years, AEG manufacturers have created various gearbox versions suited to the shapes of different real firearms. In the case of F1 or JACK the gearbox version will determine what switchboard model will be required to interface with the trigger and selector components.

Since the Fusion Engine replaces the entire gearbox the "version" will determine which Fusion Engine model can fit into the replica. At this time, only F1 supports AEGs with offset nozzles.

Generally, compatibility will be the same for replicas of the same model even if they are from different manufacturers as long as they use the same gearbox version. If you do not see your replica or a similar model in the database there may already be a compatible "Standard Nozzle" which will work. If it is not, we will gladly machine a custom nozzle for you. Since then, PolarStar has made innovative airsoft products of the highest quality, designed and manufactured in the USA.

VFC is a well known for their high quality airsoft products and accessories. We have worked with them over several months to produce complete PR receiver assemblies that meet our demanding requirements.

The only required modifications would be to change out the air nozzle and selector plate to match your AEG. We will be producing air nozzles and selector plates for different AEGs using the Version 2 gearbox in the near future. We are working on releasing Fusion Engines for the Version 3, Version 6 and M60 gearboxes with more gearbox versions coming soon.

This is mode best for riflemen and machinegunners. In "Closed Bolt" mode, the round is fired first, then the nozzle cycles feeding the next round into the hopup chamber. The BB is also given time to seat consistently between each shot improving accuracy. This mode is ideal for snipers and designated marksmen.
