PolarStar HPA Modular Regulator System MRS

Keep your HPA setup compact, efficient and ready for the field with the PolarStar MRS Modular Regulator System, available from HC2 Airsoft. Designed for airsoft players who want reliable pressure control without unnecessary bulk, this high-performance HPA regulator combines a compact profile with impressive airflow and practical features.

Standing at just 3 inches tall, the PolarStar MRS screws directly onto compatible HPA tanks. As a result, you can eliminate the need for a separate UFA and keep your air rig neat, compact and easier to manage during gameplay.

Why Choose the PolarStar MRS Modular Regulator System?

One of the biggest advantages of the PolarStar MRS HPA regulator is its integrated on/off valve. This allows you to depressurise the high-pressure side of the regulator before removing it from the tank. Consequently, it helps reduce unnecessary stress on the tank threads and O-ring during removal.

Furthermore, the MRS features an oversized 4mm piston bore, which supports high airflow and a rapid refresh rate. This design helps the regulator respond quickly to changing air demands. Additionally, it can operate at output pressures as low as 40 PSI, making it a versatile option for compatible HPA airsoft systems that require lower-pressure operation.

The regulator offers an adjustable output range of 40–145 PSI with the standard spring. However, if your setup requires a higher pressure range, an optional High Pressure Spring increases the maximum output to approximately 200 PSI. Always ensure your chosen pressure stays within the limits specified by your HPA equipment manufacturer.

Compact Design with Practical Features

Alongside its compact dimensions, the PolarStar MRS includes an integral tournament lock. This feature helps secure your regulator’s pressure setting where tournament rules require it, while the lock can be secured using a standard zip tie.

In addition, the MRS provides four 1/8 NPT outputs, giving you connection options for compatible HPA line configurations. It also supports standard HPA and SLP tanks, with a maximum input pressure of 900 PSI.

Whether you’re building a streamlined HPA rig or replacing an existing regulator, the PolarStar MRS offers a space-saving design with useful features for demanding airsoft setups.
