Polarstar MRS HPA Regulator with 42 Inch Line

  • $161.95


This 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 it's integral on/off valve. This enables you to depressurize the system prior to unscrewing it from the tank to alleviate wear and possible damage on the tank threads and o-ring.
