The Nozzle M1A1 Thompson w/ 70 O-Ring CNC 7075 (20.2mm) from SHS is a high-performance internal upgrade designed for M1A1 Thompson AEG platforms, engineered to improve air seal efficiency, enhance durability, and deliver consistent gearbox performance.

Manufactured from CNC-machined 7075 aluminum alloy, this nozzle offers exceptional strength while maintaining a lightweight profile, ensuring reliable operation under high-speed and high-stress conditions. The rigid construction resists deformation over time, making it a durable upgrade over standard polymer components.

A key feature of this nozzle is its integrated 70-degree internal O-ring, designed to create a tighter seal between the nozzle and cylinder head. This improved compression reduces air loss during firing, resulting in better FPS consistency, increased efficiency, and more stable shot-to-shot performance.

With a precise length of 20.2 mm, it is specifically engineered for M1A1 Thompson AEG replicas. Correct nozzle length is critical for ensuring proper BB feeding and optimal air seal, preventing common issues such as misfeeds or inconsistent compression.

Precision CNC machining ensures tight tolerances and smooth operation within the gearbox, promoting reliable alignment with the hop-up unit and consistent performance during repeated cycling. For best results, pairing with a quality cylinder head is recommended to maximize sealing efficiency.

Designed for compatibility with Tokyo Marui-spec Thompson platforms and most clones (CYMA, Cybergun, etc.), this nozzle is suitable for both replacement and upgraded builds.
