PolarStar Airsoft HPA F2 V2 Conversion Kit - G&G SR25 Cylinder

The new F2 is essentially a mini Fusion Engine, offering the same adjust ability and performance in a compact cylinder version. This offers a dual solenoid that can arguably compete with the PolarStar's Fusion Engine. PolarStar went out and made the F2 more air efficient and included a lightweight poppet valve that's standard in all F2. This means less air volume is required while using less PSI. The F2 comes with a spring loaded nozzle that promises consistency and air efficiency! If you're thinking about picking up an F2, this updated engine will destroy the HPA game. No other product is on par with the version 2 F2 as of right now. Be one of the first to own it.
