PolarStar F2 HPA Engine M4 Air Nozzle, Red

PolarStar’s F2 HPA Engines are compatible with M4 replicas, allowing them to fire BBs at speeds you previously only dreamed of. The F2 Engines are premium products that perform consistently no matter the hour. To ensure you get the most out of the engine, PolarStar sells this replacement nozzle.
This replacement nozzle is made of solid aluminum painted a dark red with an O-ring that achieves a perfect seal. Its length is optimized for the M4 rifle design, allowing air to flow into the chamber directly without issue.
The anodized finish isn’t just stylish, it protects the aluminum from damage.
