Madbull Thunder series 60 degree Hop-Up bucking.
The softer rubber used in the Madbull Blue Hop-up Bucking allows for greater range of adjustment and more stable spin, while the thicker rubber ensures a good air seal. Unlike many aftermarket buckings the Madbull Blue Bucking will not react poorly to silicone oil wich often results in decreased performance.
This set comes with 2 Hop-up buckings, and 2 Enhanced Hop-up nubs.
The enhanced hopup nubs are only reccomended for BB weights of .36g or heavier. Use of lighter BB's with the Enhanced nub may result in Overspin.
