The EPeS AEG POM piston head is an extremely lightweight upgrade part designed for electric airsoft guns. The piston head features two O-rings and 11 pressure relief holes that channel airflow under the seal, ensuring proper compression against the cylinder. The part is made from high-quality POM-C plastic. It includes a steel axial bearing that ensures smooth operation and extends the spring’s lifespan. The combination of well-thought-out design and premium material guarantees excellent performance and long service life, even with springs up to SP150 level. The low weight of the piston head helps extend the lifespan of the gearbox shell.
