Optimize the performance of your HPA replica with the HPA Nozzle for Fusion Engine from PolarStar. Designed exclusively for the Fusion Engine system, this nozzle is an essential component to precisely adjust the power (FPS) of your replica according to your play style and field requirements.
Made from machined aluminum and then anodized, this nozzle guarantees excellent wear resistance as well as optimal durability, even under intensive use. Its quick installation (less than 5 minutes on most models) allows players to easily modify their settings without advanced technical skills.
Available in several colors, each nozzle corresponds to a specific power level, allowing you to adapt your configuration:
Green: ideal for CQB with moderate power
Gold and Blue: perfect for a balance between range and accuracy
Black and Silver: for high performance outdoors
Red: designed for maximum power
Performance (FPS) varies depending on several parameters such as inner barrel length, its diameter, pressure (PSI) and sealing with the hop-up bucking. As an indication, with a 0.20g BB, a 6.05 mm barrel and a pressure of 120 PSI:
Green nozzle: approximately 313 to 363 FPS
Gold nozzle: approximately 350 to 400 FPS
Blue nozzle: approximately 380 to 435 FPS
Black nozzle: approximately 423 to 476 FPS
Silver nozzle: approximately 446 to 514 FPS
Red nozzle: approximately 500 to 590 FPS
This nozzle is compatible with many platforms equipped with the Fusion Engine, including M4/M16, MP5, SCAR-H, SR25, AK, G36, M249, M60 and M240 depending on available versions.
What is an HPA nozzle used for on a Fusion Engine?
The HPA nozzle regulates the volume of air injected into the replica, directly influencing the power (FPS). It plays a key role in optimizing performance and shot consistency.
How to choose the right nozzle?
The choice depends on your usage:
CQB: choose green or gold nozzles
Versatile play: go for blue or black
Long range: prefer silver or red
You must also respect the power limits imposed by your field.
Is the nozzle easy to install?
Yes, replacement is quick and simple. On most replicas equipped with a Fusion Engine, the operation takes less than 5 minutes.
Are FPS fixed according to the color?
No, FPS values are indicative. They vary depending on the length and diameter of the inner barrel, the HPA pressure used and the quality of the sealing with the hop-up.
Is this nozzle compatible with all HPA replicas?
No, it is exclusively compatible with the PolarStar Fusion Engine system. You must also choose the version adapted to your replica model (M4, AK, MP5, etc.).
Why choose an anodized aluminum nozzle?
Anodized aluminum offers excellent wear resistance, better durability and a higher quality finish for reliable long-term operation.
