G&G Piston Head

This piston head is designed for compatibility with standard Version 2 and Version 3 gearboxes. It is a universal fit for most AEGs using these common gearbox platforms.

The CNC-machined aluminum alloy provides significantly higher durability and structural integrity compared to stock plastic components. This material choice ensures the part maintains its shape under high-stress operation, leading to more consistent compression.

The rubber pad acts as a buffer to absorb the impact of the piston hitting the cylinder head during each cycle. This helps reduce stress on your gearbox shell, which can prevent premature cracking or wear over time.

Generally, no. Because this is designed as a drop-in replacement for standard Version 2 and Version 3 gearboxes, it should install without requiring permanent modifications to your internal components.

While this part is primarily designed to improve durability and cycle consistency, a better seal can sometimes lead to a slight increase in FPS. However, its main purpose is to provide a reliable, long-lasting foundation for your gearbox rather than acting as a power-boosting upgrade.
