Whether you’re upgrading an existing build or fine-tuning performance on the field, this component delivers measurable gains in consistency and durability.

Key Features

• CNC-machined duralumin construction – superior durability and precision over plastic alternatives
• Double O ring design – enhanced air seal for improved FPS stability and consistency
• H+PTFE hybrid material – optimised for longevity and wear resistance
• 20.2mm compatibility – suits a wide range of AEG gearbox types
• Direct upgrade path – straightforward installation for existing builds

Real-World Use Cases

This nozzle excels in competitive skirmish environments where shot-to-shot consistency matters. The dual O ring seal minimises air leakage during the piston cycle, resulting in tighter groupings and more reliable range. For milsim operators running extended sessions, the durable duralumin body resists wear far better than stock plastic nozzles, reducing maintenance intervals.

Technical Specifications

• Bore diameter: 20.2mm
• Construction material: CNC duralumin with H+PTFE sealing rings
• Seal configuration: Dual O ring
• Finish: Hard-anodised for corrosion resistance

Compatibility & Upgrades

The 20.2mm bore is standard across most AEG gearboxes. Confirm your current nozzle bore before ordering to ensure correct fitment. This upgrade pairs well with other air-seal improvements such as air-seal nozzles, piston heads with improved O rings, and cylinder heads. No specialist tools required for installation on most platforms.
