    MadBull Hop-Up  rubber


The 60 degree Hop-Up rubber is a little softer that the normal 80-90 degree hop-up rubbers. Thanks to this it is easier to install and use.

The hop-up rubber is made of silicone thanks to what is keeps its properties even in low temperatures while it does not become hard just like in the case of normal rubber. It performs perfectly in both, typical and below zero temperatures.


Thanks to the application of the special blocking system known as the “Shark Hopup”, there can be only one BB pellet in the chamber. In some cases, thanks to this hop-up rubber, the replica gains better FPS properties.

    What is the Hop-Up system?


The Hop-Up system is a system giving the BB pellet shot by airsoft replicas a spin movement. It uses the Magnus effect to flatten the trajectory of a flying bullet and, therefore, it makes it look similar to the trajectory of a real firearm’s bullet.


In reality, it is a properly shaped rubber or silicon seal that by touching a sped BB pellet gives it a rotation. The easiest way to explain what the Hop-Up system is to say that a BB pellet that is spun from one side generates more friction to the air so that it can turn. If the rotation will take place in the horizontal axis the BB pellet will turn upwards and compensate the force of gravitation.


The level of how strong the Hop-Up rubber touches the BB pellet determines how strong it will rotate and, therefore, go up. The heavier the BB pellets is the greater must be the pressure of the Hop-Up rubber ( while the heavier BB pellet has a greater inertia and falls down more.
