UGS, VFC HK417, Milspc - ETA August 2019
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 receiver extension. It can be used with any of the PolarStar cylinder conversion kits which are compatible with the VFC HK417 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.
The UGS™ features an integral regulator which shares the same internal design PolarStar's other compact regulators and delivers the same lightening fast performance. 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.
You are able to order the UGS™ for the VFC HK417 in two different configurations. The 2.00" configuration is designed to accept 13ci HPA tanks and 2.00" diameter buttstocks such as the included G&P R3 or optional MCS MTA stock (shown above). The Milspec configuration comes with a different rail which allows it to accept our 12g or 33g CO2 inserts which makes it possible to use traditional Milspec buttstocks.
The UGS is installed into the VFC HK417 in the same manner as the original buffer tube by threading into the receiver. It does however come with the "Type 2" output cap which features the threaded shaft and barb fitting typically used with traditional TM spec receivers. It was found that this configuration worked best due to the longer receiver of the HK417 and the Type 2 output cap offering more support for the air line which bridging the distance between the HPA engine and the regulator.
