G&G Armament Polymer Piston Head

Polymer is significantly lighter than aluminum, which reduces the impact force on your gearbox shell during each cycle. This helps minimize stress and potential cracking, especially in high-rate-of-fire builds where lightweight components are crucial for longevity.

This part is designed for standard AEG gearboxes. While it fits most common systems, you should verify that your specific gearbox uses a standard piston head interface before installation.

Yes, this component includes the necessary O-ring to ensure a proper air seal within your cylinder. It is ready for installation right out of the package.

A new piston head primarily improves consistency rather than raw power. By ensuring a better air seal, it helps stabilize your FPS shot-to-shot, which leads to more predictable accuracy and performance.

You should consider a replacement if you notice inconsistent FPS readings, a drop in performance, or if your current piston head shows visible signs of wear, such as a flattened or brittle O-ring.
