Description:Mad Bull Fishbone Bucking.
How to install:

  • (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 AEG.
  • (3) If you have problems to shoot out B.B., please apply some oil "inside" the bucking.
    About this product: Shark Hopup Bucking is original designed for 470 to prevent double feeding.
    By 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 AEG. But not all AEG could have the same results and the result could be different from one AEG to another. Unfortunately, we don't the exactly reason because each AEG has its own condition. However, we do believe that the friction (from 3 fins) appied onto B.B. will enhance the velocity.
    Rubber v.s. Silicon: To say the truth, we prefer the rubber bucking. It is duriable and cheaper. However, a lot of people prefer Silicon bucking because it seals Air better. (but break easily.)

    Best Hopup ever. I will suggest you don't use the "bone" style spacer. The performance is very good on my ECHO gun. My velocity go up to 25 fps more...

    Product Information:
    Thick rubber and silicon hopup buckings, and great spacers. Unfortunately, if you want to use this on a standard AEG, you may have some issues fitting the bucking into your hopup without some... modification.

    I ordered a G&G metal hopup for my CA Aug at the same time as this. I spent several hours trying to get either of the buckings in to the hopup correctly, and despite using lots of lubrication and effort, got nowhere. The best results I managed were when I took the rubber bucking and cut it down to half its current length, reducing the friction that was stretching and deforming the bucking as I slid the barrel in. Now it's in and the gun shoots VERY well.

    Pros:
    Buckings are thick, and should take some abuse.
    Spacer should work quite well, distributing pressure on the BB evenly for more accuracy (haven't tested yet at long range, but short range seems very consistent).
    May increase FPS slightly due to better air seal.

    Cons:
    Major pain in the ass to get on.

    I wouldn't recommend this for most people, as it wasn't really designed for AEGs to begin with. Get yourself a similar type of spacer, but a more conventional bucking that isn't quite so thick.

    Product Information:
    bought this to use in my vfc 416 and it didnt work but I tried in my king arms p90 and it works great!

    Pros:
    -prevents double feeds
    -increased velocity?
    -fixed the air seal problem
    -still used the H shaped nub in the vfc

    Cons:
    -wont fit every gun so its a real gamble buying one ... but who cares for the price
     
    Spacer
    The spacer is replacement for the hop up nub correct?
