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