Evike.com are taking pre-orders for the PolarStar Airsoft MRS and they are expecting it to be on their shelves this month... "Introducing the new Modular Regulator System (MRS) designed and manufactured by PolarStar Airsoft. This ultra 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 elevate wear and possible damage on the tank threads and o-ring.

Features:

• Modular design with different output and pressure configurations to be available
• 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
• Adjustable output pressure from 40psi to 145ps (standard configuration)
• Integral on/off valve eliminates need for a separate UFA
• Compatible with standard HPA as well as SLP tanks
• Includes Valken 36in. braided HPA hose with QD fittings

Specifications:

• Length: 3 inches
• Compatibility: Standard HPA and SLP air tanks
• Material: Aluminum alloy"
