Polarstar + VFC AIRSOFT




The HK417 is the big brother of the ever so popular HK416! Licensed by Umarex, designed for 6mm Airsoft plastic BB only. This custom build utilises the Polarstar F1™ engine, which is a high performance, universal HPA (High Pressure Air); It replaces the original gearbox components with a programmable pneumatic system allowing for higher performance, greater reliability and complete adjustability. This allows the F1™ to fill any role ranging from CQB to sniper with no additional components needed.


Unlike similar systems, the F1™ incorporates a dual purpose flow control system which allows for nozzle speed regulation and two stage firing through an integral check valve. The check valve system regulates nozzle speed based on the direction of movement while also controlling flow to the secondary firing point. This unique design promotes both smoother chambering and overall shot consistency.


Additionally this HK417 has the Polarstar UGS stock which takes 13ci bottles with an inbuilt regulator, so theres no need to run an external bottle and regulator on your back! The stock is still adjustable with 3-positions to select from.



Velocity: 500 fps w/ .20g @ 130psi

The F1™ allows for easy velocity adjustment just by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 500fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum FPS while shorter barrels will decrease it.


Air Efficiency: 1000+ shots from 13/3000 @ 1.5J  w/ .28g

The patent pending design of the F1™ allows for the most direct air path to the nozzle with minimum dead volume resulting in better flow, faster response and less air used per shot. With a VFC M4A1 as a test platform, the F1™ was able to fire over 1000 rounds from a 13ci/3000psi cylinder making it the most air efficient system PolarStar currently produces (Test Configuration: 6.05mm x 375mm inner barrel).
