Photos released by PolarStar Airsoft on their upcoming product, the Modular Regular System... "Some up close looks at our upcoming Modular Regulator System (MRS). The MRS stands 3 inches tall making it roughly the same size as your standard UFA and features an integrated tournament lock and on/off valve so the system can be depressurized before removing it from the tank."
