The product is made of rubber. The profiled indentations of the ribs inside the rubber additionally seal the entire system.

What is the Hop-Up system?

The hop-up system is a system that gives the BB pellets fired by airsoft replicas a spinning motion. It uses the Magnus effect to flatten the trajectory of a flying bullet, making it look similar to the trajectory of a real firearm bullet.

In reality, it is a properly moulded rubber or silicone seal that, when in contact with a shot airgun pellet, gives it a spinning motion. The simplest way to explain the hop-up system is to say that a BB pellet that is spun from one side creates more friction to the air, allowing it to spin. When the rotation takes place in the horizontal axis, the ball turns upwards and compensates for the force of gravity.

The strength of the hop-up rubber with which the ball comes into contact determines how strongly it rotates and therefore rises. The heavier the airgun pellet is, the greater the pressure of the hop-up rubber must be (while the heavier airgun pellet has greater inertia and falls down faster). It also works the other way round - if a light airgun pellet is turned too much, it can go over the firing line.
