Madbull - Shark Bucking w/ Fishbone Spacer (60degree) - Black/White

MB-HB-BW

Shark Hopup Bucking was originally designed for 470 to prevent double feeding. By having 3 special "fins" inside the bucking, Shark Hopup Bucking can hold one and only one B.B. tightly in the chamber. In the mean time, to our surprise, we found that this bucking could enhance the velocity on some AEGs. But not all AEGs will have the same results and the result could be different from one AEG to another. Unfortunately, we don't know the exact reason because each AEG has its own characteristics.  However, we do believe that the friction (from 3 fins) applied onto B.B. will enhance the velocity.

 

Madbull Shark Bucking w/ Fishbone Spacer Specifications:

  • Material: 1 x Rubber, 1 x Silicone
  • Spacer: 2 x Fishbone Spacer
  • Model: MB HB (SAH)
  • Manufacturer: Madbull Aisoft 

 

Why 60 Degree?

  • 60 degree rubber is softer than normal 80-90 degree rubber.

  • The softer rubber tends to create a good air seal with the nozzle

  • Softer rubber provides higher friction/grip and makes the hop up effect more pronounced with less velocity loss associated with typical hop up systems where the hard bucking must be pressed deep and hard into the hop up relief cut on the barrel. This causes dramatic reduction in speed



    • How to install:
    Apply some silicone oil inside and outside the bucking when installing onto the barrel and into hop up chamber.


    Tech Note: Hop-Up Buckings are wear items and should be changed as often as feasible. And should be replaced when upgrading or anytime the inner barrel is removed from the hop up unit. Small pin holes and tears can occur when removing and reinstating used buckings.
