G&G G&G Green Hop-Up Bucking

G&G Hop-Up Rubber

The Hop-Up bucking was made from silicone, thanks to which it maintains its properties even at low temperatures, as it does not stiffen like regular rubber. It performs perfectly in both typical conditions and negative temperatures – it retains its properties even at temperatures reaching 40 degrees below zero.

The Hop-Up bucking is adjusted to work in a system equipped with a main spring up to (and including) an M140 characteristic.

What is the Hop Up system?

The Hop-Up system is a system that gives the BB pellet fired from airsoft replicas a rotating motion. It uses the Magnus effect to flatten the trajectory of a flying projectile and, thus, makes it look similar to the trajectory of a real firearm bullet.

In reality, it is a suitably shaped rubber or silicone gasket that, by touching a BB pellet, gives it a spin. The easiest way to explain what the Hop-Up system is, is to say that a BB pellet that is spun from one side generates more air friction so that it can spin. If the rotation occurs on the horizontal axis, the BB pellet will spin upwards and compensate for the force of gravitation.

The level of force with which the Hop-Up bucking touches the BB pellet determines how strongly it will spin and, thus, rise. The heavier the BB pellet, the greater the pressure from the Hop-Up bucking must be (while a heavier BB pellet has greater inertia and falls faster). It also works the other way around: when a light BB pellet is spun forcefully, it can go over the line of fire.
