  • Three fin design reduces double feeding as well as improves hop up contact
  • Improves compression and in turn a possible FPS increase
  • Specifically designed for AEGs shooting 350 or lower FPS
  • Fishbone style spacers improve contact over standard spacer design

The Shark Hopup Bucking from Mad Bull was originally designed to prevent double feeding by incorporating 3 fins inside the bucking to aid in securing the BB. The design also improves compression which in turn improves both consistency and in some cases FPS. The 3 fin design paired with the "Fishbone" style spacer also improves the surface area which contacts the BB. This in turn improves both consistency as well as the range of hop up adjustability. The blue bucking is specifically designed for AEGs shooting 350 or less feet per second.

Material: Rubber
Compatibility: 350 FPS and lower
Package Includes: Two buckings, two Fishbone spacers

"it is extremely hard to install, near impossible to fit in a krytac hop up , also you can't use the fish bone thing in a krytac hop up so. also it tears easily

"Too thick to fit in my KWA's rotary style bucking, I actually tore one of them trying to install it. Shame, I had high hopes for it.
