Best bucking I've ever used.

The design of KWA's new Hop-up bucking has greatly increased the accuracy of my KM4 Tactical AEG. Instead of a small "hump" that protrudes into the barrel that is standard on nearly every other hop-up unit ever, this bucking uses four separate "ridges" that make more consistent and level contact with the BB when it is fired. The result is better range and much better accuracy as opposed to the old design.
You should have this in your airsoft weapon.
