This item is called flat HOP, and it is a packing that aims to suppress the energy loss that is a resistance when passing BB bullets, while allowing a long and shallow rotation of the HOP while having a small amount of HOP protrusion.
It is also recommended for custom flow velocity systems, and can be used with PROMETHEUS " HOP Tensioner Series " to further enhance performance!
★ What is HOP up?
that spins a BB bullet and extends the flight distance without increasing the power with the lift force (the force that tries to lift) generated by the rotation. The structure usually has a small protrusion at the branch in the inner barrel, and a BB bullet collides with this part and rotates, causing a HOP up. In addition, the flight distance increases and the trajectory changes depending on the amount of protrusion of this protrusion and the weight of the BB bullet.
You can expect to improve flight distance and accuracy effect.
It is an item for middle-advanced users who understand the structure and mechanism of the electric gun .
It requires more frequent maintenance than usual.
