has any 1 installed huma regulator in their huben k1?
If so what are the review about it
link is here https://www.huma-air.com/Huben-K1-Tuning-Regulator
says for mk1 & 2 hubens, i have mk4 - would this benefit too?

actually terminology of these hubens is very confusing - according to gregor videos there have been 2 major different huben k1 - but shops like airgun heaven https://airgunheaven.com/en/huben-k1-22-black make up their own terminology and selling latest version as mk4 ("Improved regulator that refills faster and more accurate, gauge exacter and improved sealing, power regulation system improved and reinforced.")

I see that it would be wise to order the reg pressure tester along with the reg as having to dump all that air for fine tuning possibly many times would be aggravating. I have two Hubens, an early K1 .22 and a just arrived K1 .25. I wonder if the reg can be used in both. Big disadvantage having to take the air tube apart to change from pellets to bullets.

So far, all I have done is to put about two mags worth of shots through it to check functionality. I casted up some of the new MP molds three ring bore riding bullets and they worked well. They hit my steel back stop really hard as it came. I haven't done any adjustments yet. So far it appears to be holding air. I haven't scoped it yet, may do that today if I find some spare time. If I get it scoped I will do some 21 yard groups as I can do them inside. Regards, Tom

limiting factor with .25 I think is finding heavy enough pellet - casting own pellets is not so convenient especially in semi-auto gun. with .22 these are perfect https://www.pyramydair.com/s/p/JSB_Beast_Jumbo_22_Cal_34_Grains_Domed_150ct/1331

I put about 120 JSB 33.95 .25 pellets through it today. Regulator seems to be settling in a bit now. Still get a few wild swings. The mag holds 17 pellets and they need pushed in til they stop. They are loose just shoved in. I will run a couple of cans of pellets through it and see if the accuracy improves. I aired up every two mags. Regards, Tom

Tom, how much pressure do you shoot? try 140-145. Huben has a new plastic dispenser; he does not like a strong discovery.

Hey guys, i just received my 2nd huben yesterday.
The first one broke down, end cap on the breach block which is held by 2 screws simply broke in half.
Now I have the latest version and shot it today. Put the reg at around 155bar and turned the power wheel down untill I noticed a significant drop in velocity.
I then shot 4 mags without problems (although not accurate, but it's not yet broken in).
Wanted to start the 5th magazine and at the first shot the valve remained open and air leaked from the barrel / magazine untill it was completely empty.
Refilled and then the valve popped back and sealed again.... Untill the next shot, it leaked empty again after the first shot on that fill.
Repeated 3 times meanwhile. And each time it does this and my whole aircylinder is empty.
I increased the reg pressure slightly and decreased the powerwheel but still same thing.
Any ideas are welcome!

Return it immediately.
I hate hearing thses stories. I would love to have a perfectly functioning Huben, but these problems are too much to deal with. Too much risk. Then add the accuracy issues on top of that, it is better to try something else with high power.
