Set of hop-up chamber elements

Set of hop-up chamber elements

The set of hop-up chamber elements is designed for the typical chambers of M4 carbine replicas and the like. The set includes the plastic elements of the chamber, such as the button, clip or arm of the chamber, a set of springs and clips and a metal barrel clip.

Using this set makes it possible to repair a damaged hop-up chamber and ensures the safety of the parts used. The elements contained in the set can also be used in stand-alone hop-up sets from other manufacturers.

What is the Hop-Up system?

The hop-up system is a system that gives the airgun 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 balloon pellet rotates upwards and compensates for the force of gravity.

The strength with which the hop-up rubber touches the balloon pellet determines how much 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.
