PolarStar MRS - Modular Regulator System The PolarStar MRS is a compact modular regulator that threads directly onto your HPA tank, standing just 3 inches tall to keep your rig lean and maneuverable. It features an integrated on/off valve that lets you depressurize before unscrewing, protecting tank threads and O-rings from wear and potential damage. Integrated on/off valve: Depressurize the system before disconnecting to protect tank threads and O-rings. Direct-to-tank design: 3" tall and eliminates the need for a separate UFA, creating a streamlined, low-profile setup. Adjustable output pressure: 40–145 psi in standard configuration; HP Spring option raises max to ~200 psi (HP Spring not included, p/n 10000556). HP Spring compatibility: Optional high-pressure spring increases performance for demanding setups (not included). Oversized 4mm piston bore: Delivers high flow and rapid response even at lower pressures (around 40 psi). Multiple outputs: Four 1/8 NPT ports for flexible hose routing and marker connections. Integrated tournament lock: Secure with a standard zip-tie for field stability. Tank compatibility: Works with standard HPA and SLP tanks for versatile use. Max input pressure: Handles up to 900 psi to accommodate a range of tanks and configurations. Modular options: Available as an Air Rig (regulator + air line) or standalone regulator (requires separate air line and fittings). Warranty: 1 Year Limited Warranty for trusted support and coverage. The MRS is designed to solve common setup challenges: a bulky regulator, wear on tank threads from disassembly, and limited airflow at low pressures. With its integrated design and high-flow bore, you get consistent performance, faster refresh rates, and a cleaner look on the field. Whether you’re building an all-in-one Air Rig or upgrading a standalone regulator, the MRS delivers reliable pressure control, easy maintenance, and flexible configuration to match your marker and play style.
