With the PolarStar UGS™ (Universal Gas Stock) you can now get the performance advantage of a HPA system without needing to be tethered to a remote air rig and still retain the likeness and function of a traditional adjustable stock. The UGS™ for the HK417 follows the same internal design as the standard UGS™ for M4/M16 series rifles but features a wider regulator body to interface with the larger diameter of the HK417 and G28 receiver extension. It can be used with any of the PolarStar cylinder conversion kits which are compatible with the VFC HK417 or G28 series such as the F2™, F1™ or JACK™ and is compact enough that it can also be used with other similar HPA cylinder systems on the market. Its integral regulator shares the same internal design as PolarStar's other compact regulators and delivers performance on par with systems twice its size. This regulator has an output pressure range of 40-130psi which is easily adjusted using a 3/32 allen key but can be locked out using a standard chrono zip tie which blocks the adjustment screw. Additionally, if you want to get a little more "omph" out of the regulator, you can install the High Pressure Spring (p/n 10000692)* which boots the maximum output pressure to approximately 200psi.
