Polarstar UGS HPA Tokyo Marui M4 with stock

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. It can be used with any of the PolarStar cylinder conversion kits which are compatible 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.

• The HPA configuration includes G&P R3 buttstock pictured.
• Compatible with the Tokyo Marui M4 series rifles.
• The UGS regulator can accept up to 900psi allowing for the use of either standard output HPA tanks as well as SLP (SLP recommended).
• Compatible with all standard 2.000" diameter tanks and most 2.000" tank stocks used in paintball applications.
• Simple zip-tie lockout/tournament lock.
• Adjustable length of pull.
• Same internal design as the other compact PolarStar regulators (Micro Reg GEN2, CGS) with cross compatibility between parts.
• The UGS™ regulator uses only 2 o-rings, promoting reliability and ease of maintenance.
• Not compatible with Fusion Engine™.
