The CYMA CGS CNC Aluminum Nozzle Set with Adjustable Valve is a precision?engineered upgrade for CYMA CGS M4 and Tokyo Marui MWS GBBR platforms. Machined from high?grade aluminium and finished with a hard?anodized black coating, this 42mm, 45g nozzle delivers exceptional durability and wear resistance while minimising internal stress. Its integrated adjustable valve allows fine?tuning of gas flow, enabling users to calibrate muzzle velocity to suit field limits or environmental conditions without replacing the entire gas system. By replacing fragile stock polymer nozzles, this set ensures a consistent air seal, stable cycling, and reduced risk of failure under rapid fire or cold weather. For experienced technicians seeking long?term reliability and enhanced gas efficiency in their AR/M4?style GBBR, this is a practical, high?performance upgrade that combines structural integrity with precise control.

Key Features

• CNC machined from high?grade aluminum alloy to deliver enhanced durability and structural integrity over stock polymer nozzles.

• Integrated adjustable valve allows fine?tuning of gas flow, enabling precise FPS calibration for different field limits or weather conditions without full system disassembly.

• Engineered specifically for CYMA CGS M4 and Tokyo Marui MWS GBBR platforms, ensuring a drop?in fit with no modification required.

• Measures only 42mm in length and weighs just 45g, reducing reciprocating mass and minimising stress on the bolt carrier group.

• Hard?anodized black coating provides excellent resistance to wear, corrosion, and abrasion for sustained performance in harsh environments.

• Ensures a consistent air seal and stable cycling, effectively eliminating common failure points such as deformation or cracking found in plastic nozzles under rapid fire or cold temperatures.

• Offers a practical performance upgrade for experienced technicians and competitive players who prioritise gas efficiency, reliability, and long?term internal durability in their AR/M4?style GBBR builds.

• Fully compatible with all TM?spec MWS M4 GBB rifles and CYMA CGS M4 GBB series.
