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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes G\u0026amp;P R3 stock that mounts over a 13Ci air tank\u003c\/li\u003e\n\u003cli\u003eCompatible with G\u0026amp;P R3 M4 series rifles and Wolverine Airsoft MTW receivers (RS-spec buffer tube mount)\u003c\/li\u003e\n\u003cli\u003eSimple timestamp\/lock for competition use\u003c\/li\u003e\n\u003cli\u003eAdjustable stock length\u003c\/li\u003e\n\u003cli\u003eSame internal design as other compact PolarStar regulators (Micro Reg GEN2, CGS).
