The PolarStar UGS™ (Universal Gas Stock) allows you to enjoy the benefits of an HPA system without being tethered to an external HPA tank via a hose. It can be used with any PolarStar HPA engine, such as the F2™, F1™, or JACK™, and is compact enough to work with other similar HPA cylinder systems. The buffer tube mounts of this product are dimensioned to real firearm specifications, making it an excellent fit for platforms like the Wolverine Airsoft MTW.
The UGS unit’s built-in regulator uses the same technology as PolarStar’s other compact regulators. The UGS regulator provides an adjustable pressure range of 40–130 psi, easily adjusted with a 3/32-inch hex key. For higher output pressure, you can install the PolarStar High Pressure Spring (part number 10000692)*, which raises the maximum output pressure to approximately 200 psi.
