PolarStar Modular Regulator System (MRS)

The PolarStar MRS™ (Modular Regulator System) threads directly onto your HPA tank, eliminating the need for a separate UFA and keeping your air rig profile to a minimum — all in a package just 3 inches tall. Its integral on/off valve lets you depressurize the system before unscrewing it from the tank, protecting tank threads and o-rings from wear.

An oversized 4mm piston bore delivers extremely high flow and refresh rate even at only 40psi, giving you consistent, high-performance output across the pressure range.
