SA Polycarbonate Piston with 14 Steel Teeth – Blue

Specna Arms polycarbonate piston with 14 steel teeth
The piston body is made from durable polycarbonate, while the stressed section consists of a complete steel rack with 14 teeth. The steel teeth offer significantly higher mechanical durability than conventional plastic teeth and are suitable for long-term use in both standard and higher-performance builds. In standard configurations, for example with an M110 spring, the full-metal rack provides a more durable solution than pistons with plastic teeth. An important design feature is the removed second piston tooth. This design provides more room for correct sector gear engagement and makes AOE (Angle of Engagement) adjustment easier, as common modifications do not require the second tooth to be additionally shortened or ground down as with some 15-tooth pistons. At the same time, in a correctly assembled gearbox, it can help reduce the risk of premature piston engagement at high RoF. The piston is designed primarily for V2 / V3 AEG platforms and others using a standard-length piston, such as V6 / V7 or M249, and is suitable not only for Specna Arms guns.
