Mad Bull Airsoft just emailed us about their newly released products that will surely help you improve firing your bbs... "Gents, We just have 2 new styles of buckings join to the family: Regular style and Shark style. It is made by 60 degree rubber which is softer than the regular buckings." These are easy to install and require not much skills. Both of them are available now so you can check with your favourite retailers if they already have these in stock.

• 60 degree rubber is softer than normal 80-90 degree rubber.
• It is much easy to install and operate the softer rubber bucking.
• The B.B. will shoot out easy without headache and need less skills to upgrade
• Cons: This item may last shorter than the regular rubber.

1. Please apply some oil outside the bucking when installing.
2. Also, remember to replace the spacer to the X type one. NOTE: X spacer is not good for all AEGs.
3. If you have problems to shooting, please apply some oil "inside" the bucking.

60 Degree Normal Shark Bucking x2 + ihbone Spacer x2

This is a normal rubber bucking with softer rubber material. 

60 Degree Shark Hopup Bucking x2 + Fishbone Spacer x2

• 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.
