SHS AEG Piston Head and Piston with 15 Metal Tooth (GG10-18)

The SHS piston with a 15-tooth full metal rack and a durable piston head increases durability, longevity, and performance in an Airsoft AEG. The full metal rack is stronger than plastic, protects the gearbox, and handles high stress and rapid firing, while a strong piston head improves compression and air seal for better consistency. 

Benefits of the 15-tooth piston

• Enhanced Durability: The full metal rack is much stronger than plastic racks, making it ideal for high-speed builds and heavy-duty use.

• Gearbox Protection: The steel rack is less likely to strip than plastic teeth, protecting the gears within the gearbox from damage.

• Longevity: This upgrade is designed for prolonged and rapid firing, increasing the lifespan of the piston and gearbox components.

• Performance: A durable piston contributes to more consistent and reliable performance. 

Benefits of the piston head

• Improved Compression: A good piston head creates a better air seal, which improves the efficiency of the compression cylinder.

• Durability: A durable piston head can withstand the impact of a high-stress gearbox.

• Reduced Stress: Some piston heads have roller bearings, which can help reduce stress on the piston and spring.
