HOP-UPS

A gel ball that has not been rubbed by a hop-up will fall faster due to gravity.

When the gel ball is shot through the hop-up, the gel ball begins to rotate, causing the upper and lower airflow pressures to be different.

The gel ball is subjected to the rising force against gravity and increases the shooting distance.

Hop-ups can reduce the direction shift of a gel ball, making the gel ball more stable and be shot at a greater distance.
