  • Three fin design reduces double feeding as well as improves hop up contact
  • Improves compression and in turn a possible FPS increase
  • Fishbone style spacers improve contact over standard spacer design

Color: Black / Clear

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.

Material: Rubber / Silicone
Package Includes: Two buckings, two Fishbone spacers

"MadBull Blue 60 degree bucking, a standard replacement for your worn out OEM bucking.
Nub was larger diameter then my stock nub, still fits in the hop up just fine, this may actually improve hop up with the slightly larger contact patch the larger diameter provides.

"Awesome bucking and nub. I have them in both my G&G CM 16 RAIDER SHORT and G&G FIREHAWK, increased accuracy and range significantly. And this is with stock 6.04mm inner barrels! This coupled with a G&G M120 spring to bring the FPS to 350-355FPS with .25 gram bb's...... Killer!
