Hop-Up bucking for the Modify hybrid barrel

    Hop-Up bucking for the Modify hybrid barrel  

The hop-up bucking is made of silicone, thanks to which it retains its properties also at low temperatures, because it does not harden, as is the case with ordinary rubber. The special design of the bucking band the perfect tightness of the barrel-Hop-Up chamber-bucking system.

    What is the hop-up system?

Hop-up is the backspin put on the BBs to increase their range via the Magnus Effect, used in airsoft replicas. The Magnus Effect flattens the trajectory of a flying projectile and thus make it similar to the trajectory of a real firearms projectile.

In practice, it is a properly formed gasket made of rubber or silicone, which, by touching the accelerated ball it makes it rotate. The easiest explanation of how the Hop-Up system works is that on one side the curled BB creates more friction against the air, which can make it twist. When the spin is on the horizontal axis, the BB will twist upward, thus counterbalancing the force of gravity.

The force of pressing the Hop-Up bucking to the BB determines how much it will be curled, and thus the strength of it’s climb. The heavier the BB, a stronger pressure of the bucking band must be applied (because the heavier BB has greater inertia and it falls down faster). It also works the other way around - when a light BB is curled too much, it can fly above the line of fire.
