Retro Arms CNC Piston 14.5 Steel Teeth

The Retro Arms CNC Piston 14.5 Steel Teeth is a high-quality upgrade piston designed for players who want to improve the durability and reliability of their airsoft AEG. This CNC-milled part is equipped with 14.5 steel teeth, ensuring optimal power transfer and longer service life under heavy loads.

Material and mounting

This piston is fully CNC-milled from strong material for maximum structural integrity. The integrated 14.5 steel teeth ensure robust interaction with the sector gear, minimising wear and significantly reducing the risk of tooth breakage under intensive use. Combined with high-quality springs and gears, this piston delivers consistent, reliable performance.

Retro Arms is known for precision machining with tight tolerances, resulting in a piston that fits into various aftermarket cylinders and gearboxes with minimal clearance.

Usage and compatibility

The Retro Arms CNC Piston 14.5 Steel Teeth is intended for use in standard AEG gearboxes that are compatible with pistons with 14.5 steel teeth, including many high-stress and high-torque setups. This piston is particularly suitable for builds with higher spring pressures, such as M120 and higher, where standard plastic pistons can show faster wear or tooth breakage.

For maximum performance, we recommend using it in combination with a well-shimmed gearbox, high-quality sector gear and a solid cylinder head setup.

Key features

• CNC-milled piston for AEG gearboxes• 14.5 steel teeth for durable power transmission• Precision construction for minimal backlash• Robust design for high-stress applications

Safety and recommendations

Always check the compatibility of the piston with your gearbox before installing it. Carefully shim the gears to ensure correct tooth contact patterns and avoid misalignment that can lead to accelerated wear. Use a spring that suits your build goal — springs that are too strong can cause damage to internal components if the shimming and setup are not done correctly.
