PolarStar F2 Nozzle No.1

PolarStar F2 Nozzle No.1 (F2 Nozzle #1)

The PolarStar F2 Nozzle No.1 is designed for users who need the correct nozzle length when setting up or maintaining a PolarStar F2 HPA engine. Because nozzle length can vary between manufacturers, PolarStar uses numbered nozzles rather than relying only on rifle model names. This helps improve fitment accuracy across different replicas and gearbox designs.

This No.1 F2 nozzle has a 1.205-inch tip length and is most commonly used with TM M4/M16, A&K PKM, TM MP5 A/SD, ICS MP5 A/SD, and G&G KAC SR-25E2 builds. Therefore, it is a useful replacement or conversion part for technicians, HPA tuners, and players who want reliable feeding and correct nozzle alignment in compatible platforms.

Choose the PolarStar F2 Nozzle size No.1 when your F2 build requires the correct 30.60mm (1.205-inch) tip length nozzle for reliable alignment and consistent performance.
