Other HPA Engine Nozzles
This page collects HPA engine nozzles for systems outside the main engine brands, plus generic or replacement nozzles that do not name an engine in the title. HPA nozzles are engine-specific, so match the nozzle to your exact engine make and model rather than to another engine or a gun platform alone.
Also searched as: HPA nozzle, HPA engine nozzle, HPA replacement nozzle.
Which engines share a nozzle?
- HPA nozzles are engine-specific, not gearbox parts: An HPA (High Pressure Air) nozzle is part of the HPA engine that replaces the AEG piston and cylinder, not a standard AEG air nozzle. Each engine family (PolarStar, Wolverine, Redline, GATE) uses its own nozzle, and they do not interchange. Within one engine family, nozzles are often offered in different lengths to suit the receiver (for example M4 versus AK versus SR25 lengths). Match the engine first, then the length for your platform.
Fitment notes & exceptions
- Match the exact engine: The nozzles on this page fall outside the main HPA engine brands, so match the nozzle to your exact engine make and model. Do not assume a nozzle fits across engine families.
