How is it grouping (any pics?)
what kit do you use to make your Slugs.
I see you are based in Sindh, Is airgun Hunting something you want/are able to do, it is such a varied province, with the Indus and the Mountains, and then the City.
PS sorry if this last line is personal.

Excellent review! To learn more abaut Huben K-1,( parts, replacement parts, tuning, etc.), you can see in youtube several videos from Fred Lee (Huben gunsmith), and others from Gregor Kamensek,how knows everithing abaut that gun! He is also also a great shooter -244 Yards shot - Airgun Depot Long Rangers Challenge-!

Hi to all.
Yes, K1 typically works better with .223 (anything between .222 to .223 works) but this dimension can only be at the rear part of the slug. Front part of the slug must not be greater than about .2185 to .2190 due to grooves in the magazine, otherwise it is impossible to load the slug in the magazine. This is why huben / my slugs only have rear band larger (approx. .223) and front bands smaller (depending on the mold model .2185 or .2173). NSA also designed the slug to be slightly in a shape of a cone at the back to get .223 at the back and still have about .2185 at the front.
In my experiences, .2185 slugs in full length can also work quite well but they must be made of slightly harder alloy. Pure lead might work OK for the first few shots but after that you get lead deposit on the forcing cone and the accuracy is gone. This is also the problem with NSA slugs.
I am still waiting for the new (2020 or 2021) version of .22 K1, that one has a different barrel and might be better in this regard...

I was told it's because the projectiles are backing out which causes the magazine to hang up. Are you seating your pellets/slugs to prevent this?

I had the same problem with my Huben K1 Version 2, and found that the regulator was faulty. I replaced the regulator with a Huma regulator, and the problem was solved. Inspect your Huben regulator for seal damage etc.
I tried to order the seals from Huben but they have changed the design of the regulator since version 2 , and I found the communication process difficult. Based upon past experiences with Huben, you will be able to order parts, and they will be sent, but upon arrival, the parts are for the latest model. For instance, I ordered a complete Huben K1 seal kit for my Huben K1 and received it, but most of the parts did not fit my version, and it was not a "Complete Seal Kit" as there were seals missing.
After numerous emails to Huben, explaining that they had sent an incomlete kit and that the seals in the kit did not fit my Version 2, I was frustrated by the lack of clarity in understanding eachother, so I decided to order a Huma Regulator, instead of a new Huben regulator, I just did not want to go through the same problem if that regulator failed.
I am happy with my decision. The only disadvantage is that the Huma Regulator is not externally adjustable. You have to strip the gun and remove the regulator to adjust it, and re install it. I have my Huma regulator set at the factory 130bar, and just use the power wheel to adjust the velocity.

+1 on the Huma reg in the Huben. I (like several others) put them in both of mine. Much more consistent than the Huben regulator.

Alejandro, thanks for stepping in. There is one issue that you can have when installing the new type of the seal (the light gray harder plastic type). The tool for inserting the seal is designed for old softer seal and can cause problems when installing the new type of seal:The problem is that the plastic part of the seal does not seat on the inserting tool properly because the inner edge of the inserting tool is not sharp enough... Before the modification:After modification:
Also important, it is not possible to get the new seal out with the removal tool as this hard plastic is so tight that the tool slips out and the seal remains in its position. There are other ways to remove the seal but you have to remove the whole action and I pushed the seal out form the front side (from the magazine side...) but not with the removal tool, you need to use a small flat screwdriver with sharp edge or something similar, but be careful not to starch the surface of the inside of the action where the seal lies... Hope this helps.
Hi Gregorio, can you post the photos of the modified insert tool again? are no longer visible and I would like to understand how to change it. Regards

Has anyone tried to encase the barrel with carbon fiber tube like how fx does it to strengthen the barrel and improve barrel stiffness?

I have been in the PCP airgun field for a couple of years now. I tend to be more on the practical "prepper" side than the hard core long range shooting that is more common. My first exposure was to the AirForce SS that I saw in Iraq being used for vector control in the camps. When I got back that was my first PCP, and I was hooked.
As time went on I wanted more "fun" and when .22 rimfire became like gold I moved to a FX Monsoon. I love that gun. But, it also has some issues and wanted more.
So I waited for the Hummingbird... A bird that ended up as a DoDo instead of a fast sleek little bird. Glad I did not spend my money on it. Others jumped on that bleeding edge, so I thought I would do my part with this one.
Here is my first review of the K1.
The K1 does not have the fit and finish of the FX guns I have seen, but it is not bad. The balance is real good and it is easy to shoot. The learning curve has been steep, because 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. The barrel looks to be a micro grove, and it contains baffles and air vents on top of the baffles.
The air tube is Ti and can fill to 5000 psi, my compressor can go to 4500 psi so that is as high as I have gone. It has a removable filter in the cap that holds the fill port, the K1 uses a fill probe like found on the FX just smaller in size.
The K1 is regulated, and my crono shows it does a good job keeping each shot within around 10 fps. It is adjustable by turning an allen wrench on the bottom of the stock.
You can then micro adjust the fps by turning a knob at the lower part of the stock.
The gauge on the gun only reads the regulated air not how much is in the tube. I like this, some will not.
You load the 19 round magazine by flipping up a small lever then load the pellets on the side and it works real well and is fast and easy, so much better than my spring indexing FX mag. It is as easy as loading a Ruger mag with .22 rimfire rounds.
Now for the important part.... How does it shoot?
It had a learning curve to get the gun set up. This is a real powerful airgun. I was shooting .33 grain .22 LR slugs through it at 1275 fps, sounded like a rimfire. It would shoot pellets even faster, but you could never hit anything. Once I figured out how to adjust the gun, things settled down. I adjusted the regulator to around 1000 fps with 16 gr pellets, the gun would then shoot in the 950 range with 18.13 JSB Exact pellets. I could then fine tune up and down to see how it shoots.
The gun is super picky on pellets in regards to accuracy, of course you might could get any pellet to shoot good if you spent the time and adjusted the guns pressure to the pellet. In the end I found that it really liked Predator Polymags and hated the JSBs.
Because it is for pest control and sticking to my prepper roots, I mounted only a 3X sight on it. I can shoot Quarter (coin) size groups all day with the polymags and set at 1025 fps. It does occasionally throw a round. This was a full 19 round mag at 50 yards.
It is as quiet as my FX Monsoon at this setting.
Once I got the gun dialed in I have shot over 600 rounds through it, 3 full tins of Polymags and several hundred JSBs. Once set up, the gun has operated flawless. First out of the box, it displayed indexing issues and air venting. A quick email to Huben helped me solve this problem. After I figured out my setup problem I have had no more issues.
Now the Bad part.
NOTHING is serviceable on the gun, Huben says that it will never need servicing, but it has baffles and there is no way to disassemble or clean anything.
That is a real issue for me. I will shoot several thousand rounds through it over the next couple weeks and time will tell. Possibly Huben is correct? I do know that lead fouling is a problem in my FX Monsoon, but it uses a piston to cycle so to be fair it is apples to oranges.
Manual is terrible, but that can be fixed.
There is nothing to adjust or even take apart on the gun. Huben does not include an exploded drawing so no clue on how to maintain the gun or fix it if it does fail.
The trigger is mush until the last moment then crisp and short, set around 2 lbs. I can live with this, but people wanting to shoot target stuff will not like this gun.
Huben does not want you to disassemble ANYTHING, but here it is naked. I would not even try to mess with anything in the air valve area of the gun without an exploded view and instructions. I did it so you will not need to. Hard to purchase an expensive piece of equipment without seeing what is inside. Would be like having a hot wife that always stays dressed!
Shoot me any questions and I will try to address them. I like this gun... and if it keeps shooting without breaking down it is a keeper and a game changer for airguns.
