"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!

"I have used several hop up bucking over the years, and I always find myself going back to the Madbull red shark bucking time and time again. They are a bit thicker than normal bucking, but I fine this helps prevent then frome tearing as easily.

"Improved my L96s range and accuracy substantially.

"Best bucking I've used to date. Ive used the king arms, Systems, Matrix, and G&P, and Angel Custom buckings and it out performs them all. Very good material and contrary to belief I've never had any problems installing it. It performs well whether in cold or hot weather. And if you add an Angel Custom tight bore you can cause some serious damage with any build!! Very pleased.

"I was having consistency issues with my Wolverine SMP. And I heard from AMPED that people with my problem have tried this and it usually fixed it. Anyways, I got it and it works well. I tried flat hopping one and effed it up. Good thing there's TWO! I am now using a prowin, red bucking, fishbone nub, and 407 prommy tbb. Shooting 350fps w/ .20s, 225ft!

"Shawn W., review of the MadBull Red Bucking:

Definitely the best bucking I've ever used.
They're great for fathop modding, R-Hops, ect.
It can be a tight-ish fit in some chambers, but that doesn't bother me.
Best airseal and FPS consistency out of any bucking I've ever used.
I've used: Prometheus purple, Lonex, G&G green, SHS, Maple Leaf, KWA 2GX, and many-many other buckings. Out of them all, the MadBull red gets the best FPS consistency, and least FPS +/- variation.
In my custom builds, I primarily use the MadBull red bucking.

Pros:
+Best FPS consistency.
+Least FPS +/- varation.
+No double shots.
+Seems to be the perfect softness vs hardness for both high FPS and low FPS setups, love it!
+Material is top quality.
+Fishbone X-Spacer actually is a little more stable than a standard nub.

Cons:
-They should maybe make a pre-flathopped version. Without the &#34;mound&#34; on the inside. For quicker install of flathop, R-Hop, and MARS-Hop systems.

"great bucking. installed on my Cybergun F.A.M.A.S. DMR and it improved fps by a lot, (which is needed when you shoot .36g BB's), and the accuracy is like 3x better than stock. would also be because of the JBU 6.03 590mm TBB

"The bucking was amazing and spacer had to be glued the hopup arm so it would not fall out. Beside that it was a easy instillation and makes a world of difference in your accuracy. over all a 5 out of 5.

"Works in the CYMA M14 ebr just a little triming is needed other wise amazing hop up!!!!

by Dakota P. on 02/12/2014

"Got this to improve my UAR. It worked. The spacer was a little too fat to fit into my hop up, but nothing an exacto knife couldn't fix. Now my UAR shoots like a dream and the bucking gives awesome air seal. Highly recommend for anyone looking to improve their hop up. but beware you may have to trim the spacer to get it to fit, but modifications are what make working on your gun fun.

"First off let me just warn everyone that these bucking are an extremely tight fit (at least into standard G&P hop up Units). However after the initial squeeze and the first hundred rounds or so, this bucking will blow you away.

The day I installed this bucking into my G&P M4 Sentry I also managed to break my MadBul 6.01 363mm tight bore barrel. As a back up I threw in my old CA 363mm (6.05) stock barrel off an old Sportline instead. I took out my Angel Custom H hop bucking and put in the provided fishbone as well. Again, it was a very tight fit, and it was nearly impossible for me to get the bucking seated perfectly inside the hop up chamber, so I threw it all together and went out to shoot, hopping that it would settle itself and it did. After about a mid cap's worth of BB's shooting straight up (despite hop up being off), it settled in and the accuracy and range increase from the bucking alone easily out did the benefits i saw from the Madbul 6.01 barrel. Make sure to lube it up well (the outside or it!!) with some silicon oil so it slides in better.

Cons:
tight, however, once in the hop up chamber the air seal is amazing.
minor... MINOR break in period.

"I installed this with the included fishbone spacer...all I have to say is WOW. This thing dramatically improves range, accuracy, and fps.
Pros:
Durable, hence it being 60 degree
A true upgrade, actually improves performance
Includes 2 buckings and 2 spacers for only $11
Helps prevent against double feeding issues
Amazing with a madbull 6.03
Cons:
You need to lube it generously
May need cutting down (mine didn't)
Might need a break-in period so that it gives enough hop
Might put you over field limits in terms of FPS
