Prometheus Air Seal Chamber Hop-Up Bucking For Airsoft AEGs (Model: 50 Degrees)

"Great bucking. Automatically noticed the difference between stock and this. The grouping is pretty tight with all stock parts besides the bucking of course.

"I own a small airsoft repair business, and this is my 'go-to' bucking for drop in upgrades. Increases seal and accuracy. I have found it to be one of the best buckings on the market. As with any bucking, it will wear down with heavy use, but it is made of a higher quality rubber than most (you pay for what you get) so it should be a while until this happens. This is an easy upgrade to make that can really help your gun's performance. Pair it with a prommy tight bore and SCS or H nub for best results.

"This is the best bucking i have used. I have used Kwa, Angel custom, Systema, Madbull, Guarder, King Arms, and modify buckings just to see what one works best at around 385 fps. I also used this in my 360fps G36 and it also worked great. I would reccomend this to anyone looking for a better airseal, range, and accuracy.

"You can feel the difference of rubber quality when handling this bucking. I modified mine to work with a concave spacer better (a modification that will generally improve performance with any spacer). It puts a really good grip on the bb. This bucking probably works BEST with guns shooting bellow 400 fps. However, I wouldn't move up to the hard type unless your pulling anything stronger than an M130. It is a KEY item to use when improving the accuracy of your airsoft gun.

"awesome bucking deffinatly worth the money used this set up in my maruzen aps2 sv with aero chamber hop-up and a 590mm 6.01 barrel deadly combo also have one in my m16

"This is a great bucking! Installed it into my KWA Sr10 and it worked wonders. I bought this bucking to obviously flat hop my AEG to increase range and trust me you will see a BIG difference.
Pros- Easy to install
Easy to sand down (if flat hopping)
Cons- It wore down WAY to fast.
I know that soft buckings tend to ware down aloft faster but I installed mine around March and I noticed HUGE tare on it which meas it wont hold a good air seal. Pretty disappointed. So I will advise other players who purchased this item, to check their bucking.

"This is the best bucking I have ever used.

Pros
Cool color
Feels strong and it'll probably last a while
Comes with a bucking and a spacer
Better than every other bucking I've used [Systema, Lonex (50 degrees), Crosman, G&P, Matrix, AIM Top]

Cons
Really expensive. These should be $15 at MOST.
Performance-wise, it's only a little bit better than a Lonex bucking. So if you're on a budget and want a good bucking, go with a Lonex. If you have to money, go ahead and get this.

"WARNING!!! DOES NOT FIT VFC 416 Hop up!!! Just purchased along with Prometheus 6.03 407mm barrel. The prometheus bucking looks like very high quality and I wanted it to work but absolutely will not in the VFC hop up unit. I called and confirmed with a tech that they are know to be too thick for certain hop ups. Nice product and I'm sure works great if it fits your gun.

"Bought this for a G&G GC series AEG, and it didn't work. There's a serious lack of description for this product which is a shame, but hopefully i can enlighten some potential buyer.

It's hard, and grips the bb's incredibly tight. So if you have a gun that isn't shooting high FPS, the gearbox will have trouble propelling the bb's through the bucking. My gun shoots right around 400FPS and it would take three shots to shoot one BB. I actually put the BB into bucking, and it require quite a bit of pressure to push it through with my finger.

Lastly, the bucking is thick, a lot thicker than my stock one. So you may require a new hop up chamber to house it properly, or just really silicone it before you install it.

I haven't had an opportunity to actually use it, but if/and when that happens, I will give a proper performance assessment.

I may have gotten a defective one, but this is what I got, and what I'm reviewing.
