Introducing the new Modular Regulator System (MRS) designed and manufactured by PolarStar Airsoft. This ultra compact regulator stands just 3 inches tall and threads directly onto the HPA tank. In so doing it eliminates the need for a separate UFA and keeps your air rig profile to a minimum. What sets this regulator apart from competing models is its integral on/off valve. This enables you to depressurize the system prior to unscrewing it from the tank to elevate wear and possible damage on the tank threads and o-ring.

Modular design with different output and pressure configurations to be available.
Oversized 4mm piston bore for extremely high flow and refresh rate even at only 40psi.
Integral tournament lock can be secured with a standard zip-tie.
Adjustable output pressure from 40psi to 145ps (standard configuration).
Integral on/off valve eliminates need for a separate UFA.
Compatible with standard HPA as well as SLP tanks.

The regulator can be purchased without a line for those who already own a line and wish to upgrade their regulator, or it can be purchased with our own braided air line. Our air line is 42″ long, super flexible and has a soft braided outer sheath.
