PolarStar F2 Nozzle – G36K / Classic Army – CA #20
The PolarStar F2 Nozzle for G36K / Classic Army (CA #20) is the platform-specific nozzle for PolarStar F2 HPA engine installations in G36K and Classic Army G36-format body platforms. The G36K is a carbine-length variant of the G36 platform — sharing the same hop-up and nozzle path dimensions but in a more compact configuration. CA #20 is the confirmed correct nozzle specification for the G36K and compatible CA G36 bodies in the PolarStar F2 range.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For G36K or Classic Army G36-format operators building an F2 HPA conversion, CA #20 is the correct nozzle specification for these platforms.
