PolarStar Fusion Engine for M249 Gearbox Series
Description
The Original HPA Rebel
The Fusion Engine™ was released in 2011 and was the first new HPA system to hit the airsoft market in over two decades. This is the system that started the HPA revolution and has set the benchmark to which all other systems are measured. Although many have followed it, the Fusion Engine™ is considered by most to be the best. This system won "Best HPA Engine" the very first year Popular Airsoft added the HPA class to their Players' Choice Awards.
This is a complete drop-in system which replaces the entire AEG gearbox with a full CNC machined lightweight aluminum chassis. It is the most adjustable system we produce with the widest range of adjustment in both velocity and rate of fire. Being a dual solenoid, closed bolt system so you are able to adjust the poppet valve (firing air) and nozzle (feeding) independently for full control over both the loading time and air volume used.
Key Features
Designed, manufactured and built in the U.S.A..
Assembled from CNC machined aluminum components.
New GEN3 design now interfaces with AEG triggers and selector plates for cross compatibility with many different models.
Capable of functioning in damp and sub-freezing climates without affecting performance or reliability.
User selectable Semi/Full Auto, Semi Auto Only and Variable Burst modes.
Open Bolt and Closed Bolt firing modes.
Independently adjustable velocity and cyclic rate.
Auto Switch mode allows for proper selector configuration for specific models.
Interchangeable air nozzles to shift the velocity adjustment range up or down.
Adjustable nozzle dwell and return to battery times to optimize feeding from any magazine.
Easy to use Fire Control Unit (FCU) with LCD display and five position joystick.
Uniform shot-to-shot air volume discharge allows for unmatched velocity consistency.
Instantaneous trigger response. Faster than an AEG with a Li-po!
Interfaces with stock AEG barrel/hop-chamber allowing for aftermarket barrel upgrades and the use of traditional AEG magazines.
Required for operation: Complete TM Spec AEG rifle , Air Rig, HPA Tank, Battery
Velocity: 550fps w/ .20g @ 120psi. |
Like other HPA systems, the velocity of the Fusion Engine™ can be fine tuned by adjusting the input pressure. However, there are also 6 nozzles available each with a different level of restriction which allows you to shift the velocity adjustment range up or down in large increments. This allows the Fusion Engine™ to have the widest velocity adjustment range of any of our systems. |
ROF: 30rps+ |
The maximum cyclic rate of the Fusion Engine™ is affected by several factors such as the operating pressure as well as the quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations. |
Air Efficiency: 400+ shots from 13/3000 @ 1.5J w/ .28g |
This system was primarily designed to deliver maximum power so air efficiency was not a critical part of its development. However, thanks to the modular design of its poppet valve, the system can be fine tuned using more restrictive valve stems and shims which allows air efficiency to more than double when operating at traditional field velocities. |
(Test Configuration: Black Poppet / Blue Nozzle / 6.05x375mm Barrel) |
