The Cylinder Set V2/V3 One-Piece Steel SHS (product code 1411) is a reinforced internal air compression upgrade designed for AEG gearbox systems, engineered to improve air seal efficiency, increase structural rigidity, and deliver more consistent FPS performance.

Manufactured by SHS, this unit features a one-piece integrated cylinder and cylinder head design, meaning both components are machined as a single steel structure. This removes the traditional sealing junction between cylinder and cylinder head, eliminating a common source of air leakage and improving overall compression stability.

The construction is made from CNC-machined stainless steel, providing high durability and resistance to deformation under repeated high-stress cycling. The internal bore is highly polished, reducing friction between the piston O-ring and cylinder wall, which helps maintain smoother compression and more consistent shot-to-shot performance.

This cylinder is a full (non-ported) design, meaning it provides maximum air volume output. It is typically used in Version 2 and Version 3 gearbox platforms, making it compatible with a wide range of AEGs such as M4/M16, AK, G36, MP5, and similar systems depending on configuration.

By removing multiple sealing interfaces and reinforcing the compression chamber, this design improves efficiency, reduces mechanical stress on internal components, and increases long-term reliability in upgraded builds.
