The Nozzle Polymer with O-Ring Seal (19.75mm) for AK from SHS is a precision air seal upgrade designed for AK AEG platforms, engineered to improve compression efficiency, enhance feeding reliability, and provide more consistent gearbox performance.
Manufactured from durable high-strength polymer, this nozzle is built to be lightweight while still offering good wear resistance and stable operation during repeated cycling. The polymer construction also helps reduce friction inside the gearbox, allowing smoother movement of the tappet system.
A key feature of this nozzle is its integrated internal O-ring, which improves the air seal between the nozzle and cylinder head. This reduces air leakage during compression, helping to stabilize FPS output, improve efficiency, and ensure more consistent shot-to-shot performance.
With a standard AK-spec length of 19.75 mm, it is designed to fit most Tokyo Marui-spec AK AEG gearboxes. Correct nozzle length is critical in AK builds, as even small deviations can affect BB feeding timing and overall air seal performance.
Precision molding ensures consistent dimensions for proper alignment with the hop-up unit, helping reduce misfeeds and improve overall reliability in both stock and upgraded setups.
