Our take: The JBU polycarbonate AEG piston is a high-quality, precision performance aftermarket upgrade. The piston body is crafted out of high-grade, impact resistant, super lightweight polycarbonate resin and features removable/replaceable steel teeth. The steel teeth are precision milled, with the second to last tooth removed for high speed rate of fire.
- Extremely high stress tolerance ensures operational perfection
- One of the finest upgrade pistons available on the market
- Full tooth design
