PolarStar Kythera SA Nozzle – #6 – TM5K / KA FAL / A&K M240
The PolarStar Kythera SA Nozzle #6 is the correct nozzle for PolarStar Kythera SA HPA engine installations in three specific platforms: Tokyo Marui 5K (TM5K), King Arms FAL (KA FAL), and A&K M240 LMG. These distinct body formats share a compatible nozzle specification in the Kythera SA range — the TM5K compact submachine gun format, the FAL battle rifle format, and the M240 LMG format all requiring the #6 nozzle geometry for reliable BB feed and hop-up interface in a Kythera SA build.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For operators building a Kythera SA HPA conversion in any of these three platforms, Nozzle #6 is the confirmed correct nozzle number.
