Polarstar Fusion Engine M4 Nozzle - Silver

The Fusion Engine has an approximate 60 - 100fps window of adjustment depending on the barrel length being used. This is accomplished by adjusting your regulator output pressure within the 80 - 120psi operating range of the engine. Changing the nozzle allows you to shift the velocity range of your rifle up or down in large increments while remaining in the operating pressure range of the engine.

The Polarstar Fusion Engine M4 Red Nozzle features:

·        Regulates Maximum Velocity: Shift your rifle's velocity range up or down significantly while staying within the engine's operating pressure range.

·        Precision CNC Machined: Ensures high-quality performance and durability.

·        Easy to Install: Quick and simple installation process, typically under 5 minutes.
