Planet Eclipse CS2 Ball Sensor Lightpipe

The Planet Eclipse CS2 Ball Sensor Lightpipe guides infrared light across the breach, allowing the marker's "eyes" to detect when a paintball has dropped in, ensuring proper feeding and preventing breaks; these clear tubes act as pathways for the light from the transmitter (left) to the receiver (right), and if blocked or dirty, the eyes can't see, forcing the marker to slow down or stop firing.
