Huben Hammerless K1

The pics are telling me that the barrel needs a good cleaning

and that the crown is in desrpate need of a good polish , 

excellent pictures of your barrel Bigalex . 

who have problems with the speed jumps, pay attention to the red spring in the regulator its nominal length is 25 mm, I have it dropped to 24.2 and problems started. with ali received similar springs price 4 usd length 25.6 mm

my new video, uneven input

Huben K1 V4 is here.......just kidding I've had the gen 2 for a year now and finally got around to making it the way I wanted it. An Fx Impact look alike. Hated the Huben not having a tank gauge and the stock was butt ugly. Decided to take apart my RTI Priest and make this hybrid. Just the way I wanted it. More air, dual regulated. Still waiting on someone to make those slugs for this bad boy. Going to the desert to max it out on power and see what velocity, shot count and groups I get.

Thanks for the honest review. I'm really on the fence over so many choices, all the while Huben has been screaming ACCURATE POWER! Now, I see I'd rather not deal with what I see as design flaws. 

Needs 2 gauges, needs blueprint and definitely needs to be self serviceable. I appreciate 2 forms of air power, speed adjustment, and being externally accessible is a plus. I can live with a creepy 2lb trigger. I can't live with a probe. Really? By now, everyone should know follow Crosmans basics in usage. The magazines mating to face is where the transfer port is. Not sure how it indexes & keeps a seal. You're kind of right. Like dating a girl & wondering what the goods look like. LOL. No no now. I am interested but with Mr. Frear's policy & geez, I really want a full sized .30 RAW, Win 70, something with WOOD, & metal, that doesn't look like Buck Rodgers left it behind in a melee to mas scoot.

Darkside316 now thats the way the Huben should look 

great job on that conversion I like the looks of it very much .



Here are some cast slugs that I'm working on for the Huben ,

I will be doing more testing on Monday or Tuesday with these . 

Hi guys! carried out work to improve accuracy, reduced the barrel length by 0.5 cm from the exit side, in the photo group of 10 shots at a distance of 50 meters, speed 303 ms, after increasing the speed to 310-313 the group became even smaller, the bullet 1.645

also replaced the red regulator spring with the spring purchased in aliexpress, the spring huben the initial length of 25 mm shrinkage to 24.1 mm, wire thickness 1 mm, spring ali 25.9 mm wire thickness 1.2 mm. The effect of changing the spring is to improve the stability of speed.

Any luck on your cast slugs ammo testing for accuracy on K-1?

I have a Huben K1 And it is Working very Well. 

But Now I want to take the accuracy a bit further And I have Some questions.

I am schootging with the Huben slugs and my groups look like this:





There is always a tight center and Some random holes around. 

When loading up the solids, Some go very easy, Some tight and some doesnt fit in the magazine. 

But When I push a pellet in, and press it out, this is What it looks like:



My tought was, Maybe soms solids get damaged wrong And Cause inaccuracy. 



Does Some of you have suggestions to make the gun more accurate When shooting with the right pellets?

thanks

Wimpy

The ones that are a snug fit seem to shoot better

from what I've noticed and one other person I know

would say the same thing , maybe there's something to it .

Not really , I'm going to deck that K-1 mold block I think the slugs

are to long and they have been jamming the gun sometimes . 



But the slugs did shoot well from my Daystate Air Ranger in .223"

Hi D-RIG,

I found this hollow point 28 gr. bullets on eBay? This bullets fit Huben’s magazine and this bullets seem to shooting well at 50 yards at 990 fps. Accuracy about the same as JSB redesigned. I’m waiting for my side-shot scope mount to come in to do some video shooting with longer distance. See couple of my favorite bullets and pellets that perform very well with my Huben. I haven’t try Huben’s bullets yet, since they are more difficult to found here in the U.S. see pictures what I have been shoot with and perform well on my K1

BigAlex...how much do those springs improve your reg pressure? Does the pressure dop less now with rapid fire with those new springs?

hi, spring replacement eliminates speed spikes if the original spring has lost its properties.

broke down flat spring, a long time was looking for a replacement, need a tough else magazine scrolls 2 holes forward.

Old & new

the red spring from the old valve, more and more rigid

In the picture above, Sept 22 @9:19 post, that crown does not look good. Looks like there is a raised ridge just at the point where the land stops. Especially visible at the top land in the photo and the first one to the right. I'd redo that crown, maybe polishing with brass bolt and compound would be sufficient bit it looks like it could be improved dramatically.
