PolarStar MRS Regulator w/ 42'' Braided Air Line Black

MRSRIGKIT / 10000547



PolarStar MRS Regulator with 42'' Braided Air Line Black

Compact Design and High Functionality: Standing at just 3 inches tall, this PolarStar MRS Regulator threads directly onto your HPA tank, eliminating the need for a separate UFA. Its minimized profile is further enhanced by the integral on/off valve, which allows depressurization prior to detachment to prevent damage to the tank threads and o-ring.

Customizable Output Pressure: The PolarStar MRS Regulator ensures flexible control over your airsoft gun's velocity with its adjustable output pressure. From 40psi to 145psi in the standard setup, it can reach ~200psi when paired with the optional High Pressure Spring, enhancing your gameplay with a wider range of tuning possibilities.

Oversized 4mm Piston Bore: With a larger than standard bore size, the regulator ensures rapid repressurization between shots, a critical feature for airsoft players needing high-performance for rapid consecutive firing.

Integral Tournament Lock: To maintain fair and safe gameplay, the regulator features a tournament lock that can be secured with a standard zip-tie. This prevents adjustments to output pressure during games, ensuring a consistent and secure playing environment.

Compatibility: The PolarStar MRS Regulator is designed for compatibility with standard HPA as well as SLP tanks, demonstrating its versatility as a high-performing addition to your airsoft gear.
