If you're planning on running your GBBR through winter or fancy mag dumping like it's going out of fashion without the dreaded "cooldown" effect, the T8 CNC HPA Adapter for M4/AR-15 AEG Magazines; CGS/MWS GBBR from SP Systems the way to do it!

This HPA adapter is designed for the Tokyo Marui M4/AR-15 ZET System and the CYMA CGS M4/AR-15 GBBR series, allowing standard AEG mags to be used along with a High Pressure Air (HPA) power source. The set includes both an EU and US HPA connector but you will need an airline, HPA bottle and regulator to run this adapter. 

The advantages of using HPA when performance is concerned include the elimination of FPS fluctuation due to the "cooldown" effect, resulting in improved shot-to-shot consistency and improved accuracy down range, especially under rapid fire. If you're already running HPA, you probably have all the bits to make this work already and experience shoulder-thumping recoil through the frosty months!

If you're running the PolarStar CGS™ Buffer Tube with your HPA build, the 33g CO2 Insert for PolarStar CGS™ Buffer Tube can up your firepower considerably! A conversion set designed for the PolarStar Gas Stock (known as the CGS™ Buffer Tube), this adapter replaces the 12g CO2 parts in the CGS™ buffer tube with parts designed for whopping 33g threaded CO2 bulbs, offering more shots before replacement while avoiding the need for an HPA bottle, airline and regulator.

Even if you don't have the CGS Buffer tube but still want to run CO2, you'll be happy to learn that the 33g CO2 Insert features standard ASA regulator threads and can be installed directly to your regulator, provided it is rated for 900 PSI.

If you're sick of running an HPA bottle and line, the PolarStar Airsoft CGS™ Buffer Tube Type 2 for HPA Engine; 12g CO2 eliminates the need entirely! Designed to mount to Tokyo Marui-spec M4 AEGs (modifications required) and the PolarStar MP5K CO2 Stock Adapter, this buffer tube is made from real AR-15 buffer tube blanks, providing a superb quality finish made from the best materials for the job.

The CGS™ interfaces with the PolarStar JACK™, F2™, F1™ or Kythera HPA engines, allowing them to be fuelled using 12g CO2 bulbs. This means you don't need the usual air bottle, regulator and line setup, which can hinder mobility for fast-moving playstyles. If 12g isn't enough for you, add the 33g CO2 Insert to use 33g threaded CO2 bulbs, offering up to 500 shots per fill!

Designed for compatibility with Milspec AR-15 stocks and most M4/AR-15 AEG stocks, the buffer tube itself offers 6 adjustment positions to suit any body type or loadout. If you're stick of line snags and carrying an air bottle around, the CGS™ Buffer Tube from PolarStar will change your game!

The Micro Reg™ GEN2 is a compact, high-performance HPA regulator designed for players who want a clean, low-profile setup without sacrificing consistency or air flow. Standing just over 2.25 inches tall, this regulator is smaller than a traditional UFA, allowing tanks to sit lower and fit more easily into compact hydration packs and minimalist loadouts.

Despite its reduced size, the Micro Reg™ GEN2 delivers a fast recharge rate comparable to larger regulators like the MRS™, ensuring stable output pressure even during rapid semi or full auto fire. Output pressure is adjustable from 40 to 130 PSI as standard, making it suitable for most HPA airsoft platforms. For higher-pressure applications, an optional high-pressure spring can be fitted to increase maximum output to approximately 200 PSI.

Internally, the GEN2 shares the same proven components as the UGS™ and CGS™ systems and uses just two O-rings across the entire assembly, improving reliability and reducing maintenance. A two-piece body design makes servicing easier, while the integral tournament lock allows the regulator to be secured with a standard zip tie for site compliance. The Micro Reg™ GEN2 is compatible with both standard HPA and SLP tanks and features dual 1/8 inch NPT outputs for flexible hose routing.

The PolarStar Braided Air Line is a high-quality 36-inch HPA hose designed for reliable performance and unrestricted movement during play. It is made from flexible rubber and reinforced with a durable nylon braided outer sheath, which reduces the risk of kinking and twisting while allowing the line to move naturally with the player.

This air line is the standard hose supplied with PolarStar air rigs and is well-suited for most chest rig, belt, or backpack-mounted HPA tank setups. The braided construction adds additional strength without compromising flexibility and manoeuvrability, helping protect the line during aggressive/agile movement and long-term use.

It comes supplied with foster-style quick disconnect fittings pre-installed on the hose. The line is ready to integrate into most HPA systems. Please note that a separate male QD fitting for the engine or regulator may be required, depending on your setup.

The PolarStar Filtered QD Fitting is designed to protect your HPA system from contamination, helping maintain consistent performance and long-term reliability. Filtering the air before it reaches your engine prevents dirt and debris from entering the system, where it could cause leaks, poor efficiency, or damage to internal components.

An integrated 80 micron filter element removes particles as small as 0.003 inches, roughly the diameter of a human hair. The conical filter design provides a larger surface area than traditional disc-style filters, allowing for strong airflow while still delivering effective filtration.

Manufactured from corrosion-resistant stainless steel, the QD fitting is built to withstand demanding environments and frequent use. It is compatible with industry-standard Foster 2 Series QD connectors, matching those used on PolarStar regulators and air lines.

Installation is quick and straightforward, with the fitting press fitting directly into standard 6mm nylon tubing used across PolarStar HPA systems. The filter element can be easily removed for cleaning and reused, and is fully replaceable if required.
