    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.

    Excellent review and thanks!  Have had my eye on the K-1 for some time and just waiting for some reviews.  I have the FX Revolution and simply love the semiauto action for varmint hunting and would like another semiauto for my next purchase.  My FX has been trouble free but only have about 500 rounds through it.

    Will be thinking hard on the K-1…about how many shots on a 4500 psi fill shooting 950-1000 fps?

    Thanks for the review of the K1 I’m getting one of these from Mike at Mrodair really looking forward to getting it as I love the semi-auto air rifles, I also have a Monsoon an have had some problems with but I still love it. I’ll probably be getting in touch asking about setting it up.
    Thanks Terry

    Thanks for the detailed review and pics.YouTube has only one video on this gun posted Long ago.

    Not being able to dismantle the gun completely is a bummer. How would one clean the Barrel if it gets dirty.? I guess the gun will have to be sent back to them for servicing. Every gun needs servicing at some point in time. O rings need replacement if nothing else. I guess time will tell. But for now the gun seems to be super accurate and can be tuned to ones preference which is a big plus. It’s also a good shooter. I would love to see the performance of this gun at 100 yards or more. Do keep us posted on how she performs.:)

    AJ3,

    I turned up the power to 1050 Fps so I could try some 75-100 yard shots. I shot 83 rounds before the gun dropped to 1040 Fps, then quit cycling.
    The gun was filled to 4300 Psi. The high was 1061 Fps, and the Low was 1040 Fps. So if shooting around 900 to 1000 Fps Im sure you could get more shots.

    Will try to shoot long range today, but I will be limited to a 3X optic.

    I pushed the gun out to 100 yards today. Hard with only a 3X sight but I could do it. after shooting at the 75 to get my elevation marks I moved to the 100. shot 19 rounds. hit the paper with all 19. Then slung a couple of JSB’s down range to see if they would hit.

    Here is my range

    19 rounds at 100 yards with 3X sight. Not perfect but not bad seeing it is just a little spot in the scope.

    Here is how the pellets look after hitting the steel. lots of energy left.

    Another 250 plus pellets through the gun, no issues. Time to do a pellet order through AOA. Any recommendations for some heavy pellets say 30 gr or more?

    Great review. I have been looking for a review since they were first mentioned. 

    Its just just hard to lay out this much cash on a gun/system that is new and untested. 

    As you said, the bleeding/leading edge..

    Today I tested some heavy pellets in the K1. 32 gr EUNJIN and H&N Rabbit Magnum 25.77 gr.
    The EUNJIN did not work, the pellets were just a couple mm to long. Shot a hundred or so of the H&N pellets. They shot all over the place at lower power, so I pushed the power up step by step. The best group was shooting at 1075 fps range. The pellet hits hard! But, the best group I could get was around 1.5″ at 50 yards. So will keep looking for heavy pellets that the gun might like. Will try the Pile Drivers once I can get them.

    Of note, this gun would shoot the 25 gr pellets at 1225 fps, just would not hold a group.
    I have not have any cycling issues during the testing. So far so good!
    Got 4 new tins of Polymag Predators, 16 gr will try my hand at a video this weekend. 

    Adjusted the regulator and loaded up some pretty copper heavies.

    The regulator was adjusted to 17 MPa

    Screen shot of the crono, This gun will produce lots of energy on target.

    It is a microgrove barrel!

    The pressure gauge sitting practically next to your neck is pretty scary.

    Scarier than a powder cartridge creating 50,000+psi just a few inches from your eye? I think the Huben would be extremely safe in comparison. The more I see of this rifle the more I wish I could have one.

    I’ve had a pressure gauge cap on a SCBA tank blow out before.  It would have done a good bit of damage to anyone near it.  Not a risk i’ll ever take.

    I think the danger is extremely low, would be like saying the high PSI bottle on a rear tank gun would blow off.
    The gun has a regulator, so even if it was to “Blow out” it is not even near the working pressure of the tank. In my case it is 1800 PSI.

    I have several thousand rounds through the gun, this is not even on my radar.

    You should recreate some of Doogy’s videos with the K1:) Should be entertaining!
