About BalystiK 14-Tooth Piston
High-performance piston from BalystiK for AEG platforms, designed for both high-speed setups and stronger springs.
The piston is made from strong PA66 polymer and fitted with a large metal rack with 14 teeth. Lightened guide rails help keep the weight down, and the total weight is only around 17.5 g.
The 14th tooth is shaped for AOE (angle of engagement), giving the sector gear more efficient engagement and a more consistent cycle.
