The Hornbill Aluminium Air Seal Nozzle for G36C is a precision-made internal upgrade part for G36C-style airsoft AEG rifles. Crafted from durable aluminium and featuring a built-in sealing O-ring, this nozzle improves air compression efficiency and helps deliver more consistent performance by minimising air leaks between the cylinder head and hop-up chamber.
 
Product Overview
The air nozzle is a key AEG internal component that directs compressed air from the gearbox into the hop-up chamber and barrel with each shot. A well-sealed aluminium nozzle not only enhances air seal and power transfer, but also withstands wear better than many stock plastic nozzles — helping maintain reliable feeding and consistent muzzle velocity.
 
Key Features
Premium Aluminium Construction: CNC-style aluminium build for improved durability and wear resistance during repeated firing cycles — stronger than basic plastic variants. firesupport.uk
O-Ring Air Seal: Integrated rubber O-ring forms a tight seal against the cylinder head to reduce air loss and enhance compression, which can support more consistent velocity and performance. 
Designed for G36C: Tailored length and shape ensure proper fit in G36C series AEG gearboxes, supporting correct timing with the hop-up unit and nozzle travel. 
Enhanced Performance: Better air sealing helps the nozzle deliver consistent blasts of air into the hop-up system, which can improve shot-to-shot consistency and overall reliability on the field. 
Direct Replacement: Drops in as a direct upgrade or spare part for worn or damaged stock air nozzles in compatible G36C AEG rifles.
