Polarstar Modular reg Sysem - MRS 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 its 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. Adjustable output pressure from 40psi to 145psi (standard configuration). Optional High Pressure Spring boots maximum pressure to ~200psi. 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. Compatible with standard HPA as well as SLP tanks. HP Spring Not Included
