This is a reinforced piston designed specifically for the company's TSG .
The body is made of injection-molded fiber-reinforced nylon, and the rack gear is made of fully machined spring steel (56SiCr7) and heat-treated to a hardness of HRC50.
The teeth are designed to prevent piston crashes, with the second tooth missing from the start of engagement and the third tooth being half the height.

Taking advantage of the fact that it does not have a full stroke, the piston length is extended and the rack gear receiving part
It is thicker than a normal piston.
It weighs 16.39g and the spring is compatible with the standard Φ15mm standard.
