Lonex Steel Ported Cylinder for MP5K Airsoft AEG Gearbox

The Lonex Steel Ported Cylinder for MP5K Airsoft AEG Gearboxes is a precision internal upgrade designed to improve compression consistency and overall gearbox efficiency in compact airsoft platforms. Manufactured from high strength stainless steel, this cylinder is built to withstand prolonged use in high stress AEG setups while maintaining stable performance. Weighing approximately 1 oz, it adds durability without unnecessary mass, making it ideal for short barrel airsoft builds such as the MP5K and PDW platforms. The ported design is specifically tuned for reduced barrel lengths, helping balance air volume to achieve more consistent muzzle velocity. Compatible with Tokyo Marui, Matrix, and other standard airsoft AEG gearboxes, this Lonex cylinder is a reliable choice for players upgrading worn internals or optimizing a custom build focused on efficiency and reliability.

Engineered with performance in mind, the Lonex steel cylinder features an internally polished surface that promotes smooth piston travel and stabilized muzzle speed shot after shot. Cooling grooves along the exterior help reduce heat buildup caused by friction during rapid firing, which can contribute to longer component life and consistent gearbox operation. Despite its steel construction, the lightweight design minimizes internal rattle, improving stealth and reducing unnecessary vibration inside the gearbox. The porting configuration is optimized for Marui MP5K and PDW style airsoft AEGs, ensuring proper air delivery without overvoluming shorter barrels. This makes it an excellent choice for players looking to fine tune compression rather than relying on generic full cylinders. Ideal for airsoft technicians, tech focused players, and competitive users, the Lonex Steel Ported Cylinder supports smoother cycling, improved consistency, and long term reliability. Whether you are repairing a worn gearbox or dialing in a high performance MP5K airsoft build, this upgrade delivers proven Lonex quality that enhances efficiency, durability, and overall airsoft performance.
