The Cyma FMR (Full Metal Rack) nylon fibre piston is one of the strongest pistons on the market.
It features a full rack of steel teeth and a sturdy but slightly flexible body to better absorb shock.
We use this piston in all of our AEG builds, it is more than capable of handling all levels of stress and is our go-to piston for virtually every build.
Cyma White Full Steel Tooth Piston Assembly
This piston is compatible with virtually all regular AEG gearboxes.
We recommend you epoxy in the rack of teeth using JB Weld Original and allow it to set for at least 24 hours before use.
The included piston head is good quality but will eat up unprotected Sorbothane pads. If using Sorbo to correct the AoE, we only recommend Airlab pads as they come with a white protective cover.
Please remember to remove the appropriate teeth if correcting the AoE.
