PolarStar JACK Nozzle – ARX160 Elite / Elite Force – #10
The PolarStar JACK Nozzle #10 for ARX160 Elite / Elite Force (EF) is the platform-specific nozzle for PolarStar JACK HPA engine installations in Beretta ARX160 Elite and Elite Force ARX160 airsoft platform bodies. The ARX160 is an Italian-designed assault rifle with a unique bullpup-style operating mechanism — its internal hop-up and nozzle path dimensions require the #10 nozzle in the JACK range for reliable BB feeding and consistent shot cycling.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For ARX160 Elite or Elite Force ARX160 operators building a JACK HPA conversion, #10 is the confirmed correct nozzle for these platforms.
