"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

"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.

+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.

-They should maybe make a pre-flathopped version. Without the "mound" on the inside. For quicker install of flathop, R-Hop, and MARS-Hop systems.
