Our take: The JBU CNC Aluminum Ported Ball Bearing Piston Head is a must have upgrade for high FPS AEGs. The ball bearing washers alleviate spring tension and increase release rate, which provides consistent FPS for every shot. The ported piston head design combined with a high quality O-ring gives this piston head excellent compression inside the cylinder, drastically improving consistency over stock plastic piston heads.
The JBU CNC piston is also incredibly durable, completely machined from a solid piece of aluminum. This piston head is sure to increase the performance of your AEG, as well as outlast all stock AEG pistons. This piston head is perfect for most high torque gearbox setups. JBU's internal upgrades are all constructed to premium standards, making them some of the best AEG upgrade parts on the market for an unbeatable price!
