PolarStar F2 Nozzle – AUG / Classic Army – CA #17
The PolarStar F2 Nozzle for AUG / Classic Army (CA #17) is the platform-specific nozzle for PolarStar F2 HPA engine installations in AUG-format and Classic Army AUG-pattern body platforms. The AUG bullpup design uses a significantly different hop-up and nozzle path layout to standard AEG platforms — the correct AUG-specific nozzle (CA #17 in the PolarStar F2 range) is essential for reliable BB feed and consistent shot cycling in an F2 AUG build.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For AUG / CA operators building an F2 HPA conversion, CA #17 is the correct nozzle specification for these specific platforms.
