RetroArms CNC piston for Tokyo Marui AA-12 / SGR-12 AEG shotgun
The piston body is made of carbon-reinforced nylon, while the heavily stressed toothed rack is made of high-quality hardened steel. This combination of materials has been selected with regard to the mechanical stresses placed on the piston during operation inside the specific AA-12 gearbox. The package includes two screws with different functions: one secures the steel rack against movement, while the other is used to attach the AA-12 piston head extension. During installation, it is important to use the supplied screw and not to use the original Tokyo Marui self-tapping screw. The piston is intended as a specialised replacement or upgrade part for the AA-12 and cannot be considered a universal AEG piston for standard gearboxes.
