UGS Type 1 12g Co2 Milspec

The Universal Gas Stock from PolarStar is a great solution for those interested in obtaining HPA system for their AR-15 style replica but they held back because of the additional tank and air line. UGS gives the user the performance advantage of a HPA in a compact system without additional restrictions or clumsiness.

It shows great results when combined with PolarStar cylinder conversion kits such as the F2™, F1™ or JACK™, but it is compatible also with other similar HPA cylinder systems on the market.

Build-in regulator shares the same internal features as PolarStar's other compact regulators. It has an output pressure range of 40-130psi and it can be easily adjusted by using a 3/32 allen key. Also for specific event regulations, it can be locked out using a standard zip tie which blocks the adjustment screw.

The CO2 configuration comes with a special rail and insert for 12g CO2 cartridges commonly used for Airsoft and Air Guns which makes it possible to use traditional Milspec buttstocks.

Type 1 is designed for use with M4 series AEG receivers that accept mil-spec threaded buffer tubes such as the G&P R3 series – requires modification of the standard gearbox shell.

Simple zip-tie lockout/tournament lock.
Not compatible with Fusion Engine™.
