Polarstar CGS Type 1 33g CO2 Milspec RS Spec version

With the PolarStar CGS™ 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 sparklet (sold separately).
• The Type 1 is designed for use with M4 series AEG receivers that accept threaded buffer tubes such as the G&P R3 series. This is where the buffer tube itself threads into the receiver. (Modification of the gearbox is required)

Specs:

• 40-130 PSI Output Range
• Works with HP or SLP regulators. SLP Recommended.
• Simple zip-tie lockout/tournament lock
• Adjustable length of pull
• Same internal design as the Micro Reg™. All internals
• except piston are interchangeable between Micro Reg™ and UGS™.
• Regulator uses only 2 o-rings, promoting reliability and ease of maintenance.

Not compatible with Fusion Engine™.
