PolarStar F2 Nozzle – AK / LCT – CA #12
The PolarStar F2 Nozzle for AK / LCT (CA #12) is the platform-specific nozzle for PolarStar F2 HPA engine installations in AK-format platforms, including LCT AK bodies. AK-format AEGs use a V3 gearbox with different nozzle path dimensions to V2 M4/M16-format platforms — the correct AK-specific nozzle (CA #12 in the PolarStar F2 range) is required for reliable BB feeding and consistent shot cycling in an F2 AK build. LCT is one of the leading AK-platform airsoft manufacturers with high build quality that benefits from HPA conversion performance.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For AK-format and LCT AK operators building an F2 HPA conversion, CA #12 is the confirmed correct nozzle for these platforms.
