Huben Hammerless K1

Jump to latest Follow Reply
I agree with Aaronchow that there is virtually no accuracy reports on the Huben yet except form Wlbryce (thank you for that) and that definitely makes us buyers or potential buyers concern. Form what I have found so far on the internet, there are two K1s in USA and one in Europe (Netherlands). Unfortunately Dutch despite the fact that they all speak English as well choose to do reviews and videos in their own language. You are the only one that gave us any information on the gun, Wlbryce. Mrodair mentioned that Huben send some of their own pellets with the gun and that they shoot better than JSB, but that still does not say anything. Anyway, they went quiet as soon as they released the video.
Considering that we know that the guns regulator works properly (consistent velocity) and that the mechanism is built to operate without stress / vibration, I have no doubt that the gun will shoot acculturate with appropriate pellets / bullets for the barrel. I assume that Huben choose the barrel to preform better with bullets (because of its potential power) and the fact that the barrel is not choked confirms that. Choked barrels can do wonders for pellets especially at higher velocity but they are usually not that good with bullets. I just wish that I would finally get the freaking thing so I can stop assuming things and test it for my self because by now I am getting on my own nerves :)

The designer of huben is called "HD Master" and known as a PCP expert in China. I knew HD master and hammerless semiauto prototype 3 years ago.

The hammerless semiauto is a great invention, maybe we all agree with that. According to recent tests， K1 is not rubbish, but is it good value for money? That's worth thinking about.

I recently spoke to the proprietor of SPairguns in Spain who told me that he has a K1 on test and that he will get them for sale in time for Christmas.
I shall believe that when it happens. But there is no chance of airgun related presents from my other half, ​and at present l do not want to spend the money required on the basis of the information that I have.
I agree that the lack of information directly from Huben is suspect and as a retired Patent Attorney I doubt their claim to Patent Protection. I am an experienced Patent searcher and can find absolutely no record of any Patent Application that might be relevant to the K1. If they have any unpublished application it would have to have been filed less than eighteen months ago, which would not tally with their claim to have been developing the gun for eight years.
Future reverse engineering of the K1 by other manufacturers might therefore be expected, and I could certainly help them with that.​​

According to what you say, you have seen the Hammerless semi auto 3 years ago and know the HD Master designer. I am not defending Huben K1 and not because i paid a deposit, but let's be logic in here. Don't you think 3 years time things can't evolve? Do you have a K1 now? if yes have you tried it and conclude with your Master Chinese wise saying "A major.." 
​From what i read Wlbryce never done any marketing pushing us to buy Huben. He just gave his Personal Opinion on it..
It's a free Website and a free country.. no?
So don't worry, we are not going to be mislead because the majority in here are Airgun users and we shall try it once the samples reach other countries..
I suggest that you give some technical facts on its strength and weaknesses, if possible..

Let's be logic.

1. Huben k1 has evolved far more than 3 years. You conclude that what i concluded was based on 3 year old information, how do you jump to this conclusion?
2. I dont have a K1 now, because i'm neither an insider nor a dealer.
3. I know what you dont know, from some insiders. 
4. “5-shot groups are 70% bigger than 2 inches @ 100 meters with 1.17gram jsb at 42J. ”
This is what I have confirmed. 
5. If some guy doesn't tell the truth of bad accuracy after testing K1, can we say a major omission?
6. Due to the benefit of the doubt, I didn't accuse anybody of doing wrong. I'm ok with Wlbryce

It uses air pressure to open the valve there is no hammer such as all other air rifles where you pull your lever or bolt to compress a spring with a hammer which then would stike the air valve.

(Wlbryce) at the beginning of this thread stats the following: 
"it is not a traditional type of airgun. It had no bolt or cocking lever and no hammer. It uses a air valve to shoot, metering the air to the breech and indexing the magazine. "

Not sure if that helped....

Hammerless airguns are not new. The first modern airgun using a hammerless valve was the Sharp Innova pump up. This was not a PCP but released all of the air from a reservoir in a single shot. However the firing action was brilliant. This was my first pneumatic rifle and it was superbly accurate. However the need to pump up the reservoir for each shot was tiring and I often thought of trying to redesign the rifle so that it could fire more than one shot in succession. Gerald Cardew, a British airgun expert and experimenter did exactly that when he designed a PCP rifle that was sold as the Sportsmatch GC2. This used a valve very similar to that of the Sharp Innova but used a regulator to prime the firing chamber with air from a main reservoir so that repeated shots could be fired using compressed air at a constant pressure.
The rifle was designed to be used in Field Target competitions and was perhaps the most expensive British airgun on the market at the time. It was regarded as the Rolls Royce of airguns and its accuracy was legendary. It did not succeed commercially however and was discontinued. Nevertheless it is still highly regarded by Field Target competitors and used examples are much sought after.

Thank you Aaronchow for your latest post. I now understand that you are not criticising Wlbryce and that you have no personal experience of the Huben K1 but that you have received insider information, presumably from someone associated with Huben, that they have been unable to make the rifle accurate at 100 metres. Thus you are just warning us what to expect.
I agree that just because a rifle has an accurate regulator and a Lothar Walther barrel, it will not necessarily be accurate as many other factors come into play such as whether the mounting of the barrel is sufficient to damp vibrations and whether the valve is able to maintain consistency. I am surprised that Huben claim only a consistency of less than 3 metres per second as I would want better than this for target use. Also is this claim for all power settings or at only one that has been selected to give this data.
I look forward to receiving more honest data from Wlbryce or other users when they get their rifles.

First, thanks to everyone for the improved dialogue!

i think I have shown and said many times that the long rang accuracy is poor. But I hold hope that this flaw will be over come.

huben shipped with the gun slugs that resemble.22 rimfire rounds that did shoot good at long ranges. If I would have anticipated the long rang problems I would have documented the accuracy of those rounds.

I am holding out that the piledriver boat tail rounds will be the solution to the non choked barrel.

I am open to all suggestions and ideas, and am happy to be the test cell Defoe others spend money on this platform.

thanks

on the road so please excuse me typing this on my little IPhone

these days forums have became battles between dealers and inventories they have to sell :) new guys just don't see it.

K1 is an interesting gun, good idea to use these industrial valves. I would like to learn more info and see internals of the gun.
From M-rod air review, I got that the gun is putting massive amount of power on full power. And that is just awesome. I think they did a good video review. Maybe it is just better to shoot on max power, with heavier ammo? Instead of so many speed setting?

Visually looking at disassembly pics that were shown on other forums, seems QC is not there on these.. but I can be wrong. Guns need development, but idea is great, and power it puts out. Price is very expensive for what is shown though, needs to be under $1K to sell. Chinese airguns so far have yet to prove themselves. Jumping in FX and Daystate price category even with great idea, is not good marketing based on everything that is available on the US market.

Maybe they used a .224 barrel? If that is the case shooting cast bullets out of it would be even better. Heaving a semi-auto .223 rig is neat.
