Piston and Piston Head Assembly | Krytac

Piston and Piston Head Assembly | Krytac – for your replica

This piston and piston head assembly from Krytac is a complete replacement part for the gearbox of your AEG. The piston and piston head are responsible for compressing air in the cylinder, which pushes the BB out of your inner barrel. If you notice that your replica is shooting inconsistently, has less power, or makes strange noises while firing, it may be time to replace these parts. An airsoft piston upgrade like this one from Krytac ensures reliable performance and a longer lifespan for your internal components.

Technical specifications

The Krytac assembly consists of a reinforced polymer piston with metal teeth for extra durability. The piston head is made from anodised aluminium with a black finish. The weight of the complete set is optimised for rapid cycles without excessive stress on the gearbox. The O-ring on the piston head ensures good air sealing in the cylinder. The teeth are compatible with standard AEG gears and the assembly fits in Version 2 gearboxes.

Compatibility and application

This piston assembly is designed for Version 2 gearboxes, which means it fits most M4, M16, and MP5 replicas. The part is suitable for builds up to approximately 400 FPS with 0.20g BBs. Installation requires experience with opening and working on gearboxes – this is not a drop-in upgrade. The assembly works well with 16:1 gears and M120 motors for fast semi-auto response, or with high-torque motors for reliable full-auto performance.
