SHS High-Speed Lightweight Polycarbonate Piston w/ 15 Steel Teeth for Version 2 & Version 3 AEG Gearboxes

Whether you're building a high-speed SSG or refreshing a well-used gearbox, the SHS High-Speed Lightweight Piston is one of the most trusted upgrades in the airsoft community. Engineered for reduced reciprocating mass without sacrificing durability, this piston combines a reinforced polycarbonate body with a full rack of precision steel teeth, making it an excellent choice for performance-oriented AEG builds.

The lightweight skeletonized design reduces the overall mass of the piston, helping improve gearbox efficiency and reducing stress on internal components during high-RPM operation. A complete 15-tooth steel rack provides exceptional wear resistance compared to standard polymer pistons, while the reinforced polycarbonate body absorbs repeated impacts and withstands the demands of high-performance spring and gear combinations. Whether you're running 13:1 gears, high-speed motors, or a programmable MOSFET, this piston is built to keep up.

Compatible with most Version 2 and Version 3 AEG gearboxes, the SHS High-Speed Piston is a favorite among technicians and custom builders thanks to its excellent reliability, precise manufacturing, and outstanding value. It is an ideal upgrade for M4, M16, AK, MP5, G36, and many other Tokyo Marui-compatible AEG platforms.
