G&G Hop-Up rubber
The Hop-Up rubber was made of silicon thanks to which is keeps it properties even in low temperatures due to the fact that it does not get stiff just like in the case of regular rubber. It performs perfectly both in typical conditions as in negative temperatures – it keeps it properties even in the temperatures reaching 40 degrees below zero.
The Hop-Up rubber is adjusted to operate in a system equipped with a main spring up to the characteristic of M140 (including).
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 quickly ). It works the other way around too – when a light BB pellet will be rotated to strongly it can go above the firing line.
