SLONG AIRSOFT Reinforced Upgrade Piston Set - High-speed version

This is a solid, precisely-molded Slong Piston made in Taiwan. The rack is steel and black-oxide coated for corrosion resistance and lubricity. It's then epoxied in place from the factory and is probably impossible to remove by hand. A single tooth omitted for AoE considerations. It looks like Slong made the lightening holes a different size and shape to reduce the chance of spring binding. Overall, this piston looks like it went through a higher standard of quality control than a lot of other brands.
