Description

PolarStar KYTHERA SA Nozzle No. 1

The KYTHERA SA Nozzle No. 1 is designed for builders, technicians and HPA users who need the correct nozzle length for their KYTHERA SA mechanical HPA setup. Rather than naming each nozzle by one rifle model, PolarStar uses a numbered nozzle system because nozzle length can vary between manufacturers, gearbox shells and hop-up chamber positions.

This No. 1 nozzle suits selected common builds, including TM M4/M16, TM MP5 A/SD, ICS MP5 A/SD and G&G KAC SR-25E2. It has a listed tip length of 0.841 inches and, unlike most numbered PolarStar nozzles, the No. 1 version is left unmarked to allow higher production volumes.

Because PolarStar’s numbered nozzle system is shared across compatible engines, the correct number can help maintain consistency when moving between supported JACK, F2 and KYTHERA-style setups. However, fitment should always be checked against the specific replica, gearbox and hop-up arrangement before installation.
