SHS AEG High Strength Polycarbonate Piston with 15 Steel Teeth #CA-552 (GG09-03)

The SHS High Strength Polycarbonate Piston with 15 steel teeth offers a lightweight yet durable design for upgrading AEGs, featuring a full steel 15-tooth rack that is resistant to stripping. This makes it a popular choice for high-speed or high-FPS builds because it can handle stress better than a stock piston. While the "polycarbonate" body is lightweight and strong, some may prefer a glass-fiber nylon version for even greater wear resistance, although the polycarbonate version is often considered a significant upgrade from stock. 

Benefits of the SHS piston

• High durability: The full steel 15-tooth rack is much more resistant to stripping under stress than plastic or half-metal teeth designs.

• Lightweight: A lighter piston reduces mechanical stress and can improve the rate of fire and trigger response.

• Cost-effective: It is a very affordable upgrade that provides a significant performance increase over a stock piston.

• High performance: This piston is recommended for high-speed and high-FPS builds, allowing for more stress and wear.

• Compatible with most AEGs: It is designed to be a drop-in upgrade with little to no modification required for many gearboxes. 

Potential considerations

• Material: While the polycarbonate body is strong, some high-performance builds may benefit more from the even greater wear resistance of a glass-fiber nylon or full metal piston.

• AoE correction: For best performance and durability, some users may need to file down the last tooth to correct the Angle of Engagement (AoE).

• Compatibility: In some rare cases, fitting may be tight and require minor adjustments to the gearbox shell.

• Gear set: For maximum durability, it is recommended to pair this piston with a high-quality gear set, as it is designed to be the component that fails first in case of a jam to prevent damage to other parts.
