The Action Army Nylon & Fibreglass AEG 14 Tooth Piston is built for AEG users who want a dependable replacement piston for Version 2, Version 3 or Version 6 gearboxes. Made with a glass-filled nylon body, it offers a balance of strength and controlled weight that suits routine servicing as well as fresh internal builds.
Its 14-tooth design combines six polycarbonate teeth with eight metal teeth, giving you a practical mix of durability in key wear areas without turning the piston into an unnecessarily heavy component. In use, that helps maintain smooth gearbox cycling and makes it a sensible choice for players looking to refresh worn internals or keep a dependable backup part on hand.
For tech work, compatibility is straightforward across common AEG gearbox platforms, making it easier to match into many standard builds. It also sits naturally alongside other gearbox parts, shims and AEG internal upgrade components if you are already working through a full service.
