Prometheus Air Seal Chamber Packing / AEG Hop Up Bucking (Soft Type)

12 Customer Reviews

"By far the best performing bucking on the market. BY FAR.

The G&G Green is a close second, and probably a better choice for those on a budget.

Yahs.

"Sweet thing! Pretty awesome! Get it! I'm not sure how long it will last but it seems pretty high-quality (c'mon I mean it's Laylax/Prommy, how can you get better than that?

"Before you read this, I'm not too knowledgeable on parts for AEGs yet. I'm just giving an honest, unbiased review on THIS product. No comparisons.

I bought this as a replacement for the Bucking my Madbull Ultimate Hop-Up Unit came with. It wasn't really working right for me, it kept losing it's seal still after checking the space between the Hop-Up System and Gearbox, so I looked to other Buckings.

I decided to look at Prometheus, since I heard they keep pretty good seals. I'm not disappointed. The FPS stayed pretty consistent, averaging between 3 to 10 FPS of a difference. Not to mention it beefed up the FPS a bit as well. The nub for the Hop-Up arm is pretty great too, doesn't place more pressure on the Bucking than it needs too, allowing for pretty accurate tweaking on the Hop-Up.

For a Soft Type Bucking, this does a pretty good job. I'm going to keep using it until I try the Hard Type from Prometheus.

Pros:
Keeps a great seal.
Nub allows for good precision tweaks on Hop-Up.
Increases FPS and FPS Consistency

Cons:
A little over priced by a few bucks.

"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.

"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.

"Installed one in a metal G&P AUG / M14 hopup unit over an AEG barrel, and another to build a custom hopup for a revolver using an Orga widebore intended for the VSR-10. I flat hopped in both cases, which meant I had to turn the bucking inside out and carefully shave down the hopup bump inside it.

As they say, this is a good bucking, consistent and very durable, yet elastic. If you’re buying this item, you will probably be interested in at least flat-hopping your hopup, which is the one sort-of hiccup here. Once your bucking is sanded, you can sleep at night confident U R L33T 0P3R@ToR!!!

"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.
