PolarStar MR “MicroReg Gen 2” Micro Regulator Air Rig (Regulator Only)

The PolarStar MR MicroReg Gen 2 Micro Regulator is a compact, high-performance regulator designed specifically for HPA airsoft systems. Built for reliability, precision pressure control, and easy maintenance, the MicroReg Gen 2 delivers the consistent air output required by modern HPA engines while maintaining an ultra-compact profile.

Manufactured in the United States by PolarStar Airsoft, the MicroReg Gen 2 continues the proven performance of the original MicroReg while introducing a simplified internal design that improves manufacturing efficiency and long-term serviceability.

Whether you’re building a new HPA rig or upgrading your existing setup, the MicroReg Gen 2 provides stable pressure regulation in a lightweight and extremely compact package.


Ultra-Compact Low Profile Design

One of the most impressive features of the MicroReg Gen 2 is its extremely compact footprint. Standing less than 2.25 inches tall, this regulator is smaller than many traditional universal fill adapters (UFAs), allowing players to run a streamlined air rig without unnecessary bulk.

This low-profile design keeps your tank and regulator setup lightweight and balanced, making it easier to maneuver during fast-paced gameplay. For players who prioritize mobility and comfort, the MicroReg Gen 2 is an excellent choice.

Despite its small size, the regulator still delivers powerful and consistent pressure output required for demanding HPA airsoft systems.


Precise Adjustable Pressure Output

The MicroReg Gen 2 features a fully adjustable output pressure range from 40 PSI to 130 PSI in its standard configuration. This wide adjustment range makes the regulator compatible with a variety of HPA engines and airsoft platforms.

Players can easily dial in the perfect pressure for:

  • PolarStar HPA engines

  • Other HPA-powered airsoft rifles

  • DMR builds

  • Speedsoft setups

  • Tournament configurations

Stable and consistent air pressure is critical for maintaining accuracy, efficiency, and shot-to-shot consistency. The MicroReg Gen 2 delivers reliable regulation to help keep your HPA system performing at its best.


Simplified Internal Design

A key improvement in the Gen 2 version is the simplified internal construction. The regulator uses only three O-rings in the entire system, reducing the number of potential failure points and making maintenance significantly easier.

By redesigning the internal body, PolarStar was able to use the same piston used in their UGS and CGS systems, eliminating unique components that previously complicated production and servicing.

This redesign removed the center O-ring that was previously required, reducing internal drag and simplifying assembly.

The result is a regulator that is:

  • More reliable

  • Easier to maintain

  • Simpler to service

  • Highly durable

Although the internal design has been simplified, the performance and pressure regulation remain identical to the original MicroReg.


Improved Serviceability and Maintenance

Because the regulator now uses fewer internal components, routine maintenance is easier than ever. The simplified O-ring layout makes cleaning, servicing, and rebuilding the regulator much faster for both technicians and players who maintain their own gear.

With fewer moving parts and seals, there are also fewer wear points, improving long-term reliability and reducing downtime.

This is particularly valuable for players who frequently attend events or rely on their HPA systems during competitive gameplay.


Integrated Tournament Lock

The MicroReg Gen 2 also includes an integrated tournament lock system, designed to comply with common airsoft field regulations. The lock uses a standard zip tie, allowing referees or field staff to secure the regulator once the desired pressure setting has been verified.

Unlike some regulators that require additional accessories or moving parts, the integrated lock system is simple and effective, ensuring compliance without adding complexity.


Proven PolarStar Performance

PolarStar regulators are widely known in the airsoft community for their exceptional reliability and consistent performance. The MicroReg Gen 2 continues this tradition by offering a regulator that performs flawlessly under demanding conditions.

The redesigned body slightly changes the external appearance, but the regulator maintains nearly identical dimensions to the original Gen 1 model, ensuring compatibility with existing HPA setups.

Thanks to reduced piston drag from the simplified O-ring configuration, the regulator is technically slightly more responsive, though performance characteristics remain consistent with the original MicroReg design.
