MadBull 60 Degree Shark Bucking With Fishbone Spacer (Color: Black / Clear)

"This is the only bucking out of about 10 I've tried that worked well for me. I'm using rotary hopups, so don't know about regular hopups. The lip shape is perfect, short and curves inwards, although the bucking is thick and may have trouble squeezing inside. I used a prowin and 2 other plastic prowin clones. Umbrella armory uses this very bucking (blue) for the lvoa (rhopped), which Dutch the hooligan uses. The only thing is it rips pretty easily so you have to be very careful with it. I ripped 2 already trying to flat hop it and taking it out of the chamber.

"I'm an airsoft technician; I was trying to get a customers SCAR-L to A: stop double feeding, and B: actually have some freaking compression. everything in the gun looked fine. I didn't understand why the gun was shooting so poorly. So I thought "what the heck" and tried this bucking in it. sure enough, It solved the problems. Better compression, and no more double feeding.

Some of the other reviews said that It would be tough to install, but I personally didn't have any issues. the only thing I would even mildly consider to have been difficult about the install, would have to be the hop up nub. that part was a little tight.

*Great bucking.

*worth the money.

*you get 2 of them.

*harder material than a stock bucking

"This is the best bucking I have ever had. it effectively doubled the range on my stock AK47, and Increased the fps by 20.


Pros:
Major range difference
More accurate
Cheap and effective
Can deal with high fps
Madbull


Cons:
Both of my spacers where deformed, so it wouldnt go into my hop up
Very tight fit
Had to adjust a couple times to make it work, and taking apart a AK is a B**ch.



WORTH EVERY PENNY, HIGHLY RECOMMENDED. 4 STARS DUE TO SPACERS.

"Alright I put this in my softair thompson M1A1 but it took over an hour. It does improve feeding, fps, and range but it had an impossibly tight fit in my hop-up unit. I had to cut off part of the end in order to make it work. Also the spacer was too wide to fit so I had to do extensive modification to make that fit. Once in place though it works great. Do not be discouraged by my troubles it was probably just the irregularities of the thompson.

"Amazing bucking for mods like the flathop but only if you use a concave spacer, flat nub, or h nub. For normal applications it's fine, but I've found that when it's not broken in, it does not apply sufficient hop if you look down your inner barrel. But, like I said, for flathopping, this thing is wonderful, hop is evenly applied, etc. Also, it's very durable hence it being 60 degree.

"Great buckings, they have a tight fit in nearly all my hop units. Strange.
Besides that they are great


Pros:
Increase range+accuracy
Cheap ($6 a pop)

Cons:
Tight fit. You may need to fiddle with it. I ended up just clipping a bit off of the end to get it to fit better

"This is an awesome bucking, Just installed on my upgraded ak47, good accuracy, and unlike my stock AEG bucking that required me to turn the hop up on alot, this barely requires me to put the hop-up on to get the same results.

Pros:
Good bucking
harder plastic than a normal bucking
Decent pricing

CONS:
The bucking is too long (simply use a sharp exacto knife to cut it down to fit in the hop up unit correctly)
The harder plastic makes this bucking a little bit bigger, meaning a tighter fit (It took me 15 times to get the bucking in correctly placed, I had to use extra silicon oil to get the bucking in because this bucking is larger than others


Overall, good bucking, just the fact that it is larger than the normal size hop up unit and that it is hard to install made it a bummer. Once its in though, its a perfect bucking.

"Good bucking. Gives good grip on the bb, and the spacers work very well on improving the consistency of the hop-up. However, these buckings are thicker than both the stock bucking, and offerings from Systema and Guarder, so be warned that they are harder to install.

"it is extremely hard to install, near impossible to fit in a krytac hop up , also you can't use the fish bone thing in a krytac hop up so. also it tears easily

"Too thick to fit in my KWA's rotary style bucking, I actually tore one of them trying to install it. Shame, I had high hopes for it.

"Installed the Shark and Fishbone today on a L85. Had it apart,replaced and assembled in about 20 minutes *pats self on back*. Also installed a Madbull Psg1 barrel and Zombie killer mock silencer. So not sure if its the bucking or the barrel, but it dose group very well. and don't look half bad. i plan to install the second shark and fishbone in a Jing Gong Aug*crosses fingers*. Along with a Matrix 120 spring and a Tenergy 9.6 2300mAh. More on that later. Thank you Evike, cant wait for it to get here. peace and fry bread grease.

"Doesn't work very well for this price. It performs like a stock bucking would. Just go with systema

"This was an ok Bucking... good replacement for an old CA bucking but I really did not notice any difference in the gun with this new bucking other then it works great just like my stock CA...
still a good buy

"Fits very loose around the barrel when I put it on there was an obvious range decrease so that kinda sucks

"Just putting it out there that this bucking does not fit in a Lancer Tactical PDW even though the gun is M4 compatible.
