Polarstar F2 Fusion Engine Nozzle - VFC M4
A length-matched nozzle for the F2 Fusion Engine
This nozzle belongs to the numbered F2 nozzle series, in which each number is matched to the exact length required by a specific gun model from a specific manufacturer, since that length differs between manufacturers even for the same nominal model. Together with the F2 Fusion Engine's light or heavy spring, it sets the nozzle's loading force.
