Retro Arms POM Piston with 15 Steel Teeth for PTW M4/M16 (Systema/AK/Celcius) AEG (GG07-04)

The Retro Arms POM Piston with 15 steel teeth offers increased durability and performance for PTW M4/M16 airsoft rifles, primarily through its wear-resistant steel teeth, lightweight yet strong polymer body, and optimized 15-tooth design. It is engineered to handle high-stress applications, improve performance, and ensure reliable operation over time, making it a suitable upgrade for high-FPS or high-ROF builds. 

Key benefits

• Enhanced durability: The piston features a full rack of CNC-milled and heat-treated steel teeth, which are significantly more wear-resistant than standard polymer teeth. The piston body is made from a durable, injection-molded polymer reinforced with carbon fiber and molybdenum, which increases strength while reducing friction.

• Optimized performance: The 15-tooth design (including the pickup tooth) is engineered to provide a more optimal Angle of Engagement (AOE) in most gearboxes, which can reduce wear and tear. The final tooth is also often shaved to further improve gear pickup and minimize stress.

• Reliable operation: The combination of a strong steel gear rack and a robust polymer body makes the piston capable of handling high-FPS and high-ROF (Rate of Fire) setups.

• Compatibility: This piston is designed to fit and work in PTW M4/M16 airsoft AEGs (Automatic Electric Guns) from brands like Systema, AK, and Celcius.

• Lightweight design: Despite the steel teeth, the piston is still relatively lightweight due to its polymer body, which helps maintain a good rate of fire and overall performance.
