PolarStar High Pressure Spring for PolarStar MRS "Modular Regulator System"

Features

• Compatible with the MRS regulator only, and intended for use of systems capable of operating at 145 PSI
• Simple installation into MRS Regulator system
• Safely increase pressure ratings without the need to shim any components

Looking to get a little more "ooph" out of your MRS regulator? Well then you are in luck since this beefy spring will do just that. Changing out the spring can be done in a matter of minutes and will safely increase the output of your regulator to ~200psi while still retaining the ability to operate at 40psi.

Although some pressure gains can also be accomplished by shimming the original spring, changing the spring is more beneficial than the typical shim method. When a spring is shimmed, the whole pressure range shifts up so you lose your low end pressure range. By simply changing the spring's rate, the regulator still has the ability to operate at 40psi. Even though the high pressure spring will technically not allow the regulator to recharge quite as quickly at that low pressure in comparison to the standard spring, at conservative rates of fire it is not going to be noticeable.

About PolarStar

PolarStar Precision Airsoft was formed in January 2009 to fill a need for high quality, precision manufactured airsoft components designed for performance and longevity.The 2011 release of the patented Fusion Engine HPA system marked a change in direction for PolarStar. The focus shifted from developing upgrade components within the constraints of existing systems to developing innovative HPA systems and accessories which replace the aging AEG technology.PolarStar Airsoft is a division of PolarStar Engineering & Machine (PSE&M), a unique blend of tenured American toolmakers and a full service CAE/CAD/CAM (Computer Aided Engineering, Design, and Manufacturing), special crafts machine shop keeping alive our proud manufacturing heritage of Made in the USA. Founded in 1997, PSE&M began by servicing the automotive racing industry through the design and producing systems and components from art to part. Operating under the auspices of the Delaware Association of Professional Engineers, we retain a Professional Engineer (P.E.) on staff to ensure and certify all design and engineering standards are met. In addition to our own product line, PolarStar also offers engineering and manufacturing services tailored to the airsoft industry.
