    Set of Hop-Up chamber elements


The set of the hop-up chamber elements are designed for the typical chambers used in the M4 type carbine replicas and similar. The set includes the plastic made elements of the chamber, such as the knob, clip or the chamber's arm, a set of springs and clipses and a metal barrel clip.


The application of this set allows to repair a damaged hop-up chamber and gives the certainty or the applied parts. The elements consisted in the set can also be used in the other manufacturer's stand-alone hop-up set.


    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.

I had some problems fitting these in my hopup unit, I wouldn't recommend put different brands in one hopup unit.
