Polarstar UGS Type 2 33g CO2 Milspec for Tokyo Marui M4

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 33gr CO2 sparklett (sold separately). This Type is designed for use with tm Spec M4 series AEG receivers. (Modification of the receiver and gearbox may be required)
