Our take: The Lancer Tactical Nylon Fiber Lightweight AEG Helical Gear Set piston is a high-quality, high torque performance upgrade, perfect for Airsoft players with an upgraded high tension spring. The piston body is crafted out of high-grade lightweight and durable Nylon Fiber and features 15 Reinforced Carbon steel half teeth. This piston's sturdy construction ensures that it can pull even the highest tension AEG Springs. The piston is designed for super high torque performance. The Lancer Tactical Nylon Fiber Lightweight AEG Helical Gear Set piston can only be used with a Helical Gear Set.
