Hop-Up Bucking

A black hop-up bucking, designed for more powerful replicas (with an M120 spring or stronger), as the material from which it is made is more resistant to wear than silicone.

What is the hop-up system?

Hop-up is a system that spins BBs fired by airsoft guns. It uses the Magnus Effect to flatten the trajectory of a flying bullet and thus make it similar to the trajectory of a real bullet from a firearm.

In practice, it is a properly formed rubber or silicone gasket, which, when touching the speeding ball, gives it a rotational motion. The simplest explanation for the Hop-Up system is that a spin-up BB on one side creates more friction with the air, which can cause it to turn. When the spin takes place in the horizontal axis, the ball will turn upwards, thus balancing the force of gravity.

The force of pressing the Hop-Up bucking against the BB determines how much it will be spun, and thus the lifting force. The heavier the BB is used, the stronger the pressure of the bucking must be (because the heavier BB has greater inertia and falls downwards faster). It also works the other way around – when a light BB is too much spin, it can fly above the line of fire.
