Airsoft Pistons

If you are looking for a replacement piston on the cheap with no performance compromises, CYMA to the rescue! The CYMA Steel Tooth Piston Set w/Piston Head includes the piston itself, a piston head and a piston head O-ring. The piston has a full 15-tooth rack of steel teeth, improving strength while keeping overall weight manageable, making it great for high performance builds. The set is designed for version 2 and version 3 gearboxes and will be provided in a random colour; either blue or green.

Take your AEG to the next level with a revolutionary Piston. It has been redesigned to ensure a premium performance. The Nightstalker piston has eradicated all the common weaknesses of an AEG piston to create an almost flawless design. Firstly, it has been constructed from a reinforced polymer, one that can pull stronger springs without causing damage to itself. It also has a drop-in angle of engagement (AOE) which helps distribute the force evenly on the teeth of the piston rack, reducing the risk of premature wear or breakage.

The stress points of the piston have been revised to spread the wear between 3 contact points and drastically reduce the load on each tooth. Another upgrade is that the piston rails have been revised to reduce friction, this removes the wobbling of the piston against the gearbox and keeps it completely straight. All these revisions and enhancements make for a consistent improvement in FPS and performance. Make your AEG premium, for real.

A complete upgrade Cylinder set for AEGs which includes: Cylinder, Piston, Cylinder Head, Piston head and Nozzle. Improve your air seal and shot for shot efficiency today for improved range and accuracy.

If you have stripped your piston and need a replacement, here ya go! The KRYTAC Piston & Piston Head Assembly V2 for M4/AR-15 AEG is a replacement original parts set including a polymer piston with a 4-tooth steel rack and a polymer piston head with pre-installed O-ring. The set is designed for the Krytac Trident AEG series but is compatible with M4/AR-15 AEGs equipped with a version 2 gearbox. 

FPS Softair brings you the Polymer Piston w/Steel Tooth Rack for Marui NGRS SCAR-L/H, featuring a technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight.

The loaded technopolymer assures great mechanical resistance and dimensional precision. The tooth rack was manufactured through the use of MIM (Metal Injection Moulding) technology since this production process guarantees dimensional accuracy and sturdiness equal to those of solid machining.

The metal injected is SAE 4650 steel, currently considered the best for this type of use. The sliding guides are designed to minimize friction and hold the lubricant for a long period of time, so you can be safe in the knowledge that your TM NGRS SCAR will have reliable and long-lasting functionality.

FPS Softair brings you a super high quality M4 piston with a technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight. This is compatible with Tokyo Marui NGRS M4 gearboxes, aka the Version 9 gearbox. Please note, this piston is not compatible with the TM NGRS SCAR-L or SCAR-H.

If you've had a piston failure, G&G Armament to the rescue! This 14-tooth AEG piston is compatible with most Airsoft AEGs (NOT PSG-1 or some SR-25s) and boasts a full steel tooth rack for maximum strength. A great replacement part to have around just in case, this piston takes standard AEG piston heads and the tooth rack is full-width, ideal for most sub-350FPS builds. 

If you are looking for an excellent replacement piston for your AEG then look no further! The RetroArms 14.5 Steel Tooth Piston is the perfect piston upgrade. Its injection moulded carbon-reinforced polymer ensures premium quality and consistency, the fourteen-and-a-half steel teeth are highly wear-resistant and greatly extend the lifespan, and it also keeps your Airsoft rifle performing up to standards. The half-tooth allows the piston to be picked up by the gears more easily and minimises the chance of the teeth bouncing off the gear and causing internal damage.

The RetroArms 14.5 Steel Tooth Piston is great for high-performance builds and is designed for version 2 and version 3 gearboxes. Make your AEG premium with this simple upgrade piece!

FPS Softair brings you a high-quality piston with a carbon fibre-reinforced technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight. This is compatible with Tokyo Marui-style Version 2 and Version 3 gearboxes.

This Superlight piston reduces friction for an increased rate of fire, in addition to the overall reliability of your rifle. The sliding guides are designed to minimize friction and retain the lubricant for a long period of time and the rack seat is decentralized to favour the coupling between the piston teeth and those of the sector gear.
