Redline HPA Nozzles

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.
