More info

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 AR-15 stock. It can be used with any of the PolarStar cylinder conversion kits 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 follows the same design as the highly regarded PolarStar Micro Reg and delivers the same lightening fast performance. This regulator has a 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.

This configuration is designed to accept 12gr CO2 sparklett (sold separately). This Type 1 is designed for use with RS Spec threaded M4 series AEG receivers. (Modification of the receiver and gearbox may be required)
