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.

Upgrade your AEGs piston head to improve air seal and increase the efficiency of airflow through the cylinder. This piston from FPS Softair has ports on the front to push out the O-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.

Constructed from CNC aluminium Ergal, which has been anodised, the piston head features a smooth precise surface. The piston head has ports on the front to push out the O-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.

The ball bearings help reduce tension created by the spring compressing and expanding, this combined with a ball bearing spring guide is the optimal set up to keep your spring in good shape.

This is the most advanced version with 8 ventilation holes for higher speed and rate of fire, double O-ring and ball-bearing. This head is designed for version 2 and 3 gearboxes but may fit other types.

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.
