I replied that knurling could be an option but must have said something nefarious. It’s waiting for mod approval….?

@Kenjeepman Getting them to fit is one thing. Now you have to see how they shoot on a consistent basis.

This will be the deciding factor. I developed the utility knife blade knurling so I could keep the knurling consistent. It’s not some magic fix all, but did work great in my application.

Knurled area of slug measured .179 which is the mag minimum. Pushing it through the barrel it mics up right at .177 confirming the barrel is right at .177.
Huben needs to make the .177 mags hole size smaller.

Huben made this pistol with the intention to shoot pellets. Pellets would not fit if the mag chambers were small enough to fit .177-.178 slugs. The head would fit but the skirt would get hung up.
Krazcool Airguns used to sell a custom .177 mag. Maybe he still has some.

I have a .177 and shoot only RWS Supermag 9.3 and 700fps. I also load 4 pellets use 3mm ball Allen key that comes in tool kit and seat the pellet still they hit the mag stop. My perfect backyard air pistol.

Hi all! I have problems with my brand new Huben gk1 caliber .25 Ver 3+. It's making pretty bad groups with Discovery scope installed at 25 yards. Groups are 4-5 inches. Scope is good Discovery 4-16x44 and the mount is good quality as well. First I thought the problem is me but other more experienced shooters gave it a try and they said that it really is shooting bad. Do you think huben shop may approve this as warranty situation? After all the gun function properly its just shooting bad.
After all these vids and reviews on the net I really expected hole in hole at this distance with scope on it. And I only use JSB pellets 25 and 34 grain, no slugs no experiments..

Not using moderator till now. Next time I'll try huben moderator lets see how it works. May be velocities are a bit slow I know best for pellet is 850-930 FPS I think I shoot below that. But still way to bad performance. Do you think is good idea to contact seller or its pointless what would be your advice? Thanks!
And after 300-400 shots I cleaned the barrel but performance remain the same.

With pellets you should be ok 600-700 fps
Do you own a chronograph?
I have both 22 and 25 Gk1’s. I can not use the hubben moderator with the 25 .. poi was all over the place.

As far as I know moderators have different influence on groups, its random, sometimes makes them tighter sometimes wider. My chrono broke I need new one so no don't own one right now, but I can borrow next time. Considering power adjustment I set velocities should be in decent range. Idk I hope I don't have this barrel misaligment that I've seen some reports about.

Have not heard of that. Are you talking about misalignment of the barrel and the mag? I can see if that were the case it would damage the pellet and cause accuracy issues only way to check that is by taking the gun apart.

Yes I was talking exactly about this barrel-mag misaligment. But I am making pure speculation here. Its just I can't find another reason why it has such poor accuracy.
My request for help to you all was whether you advise me to talk to the store assuming that it is a warranty issue or to take it to a service center to disassemble it and look for the problem. Do you think inaccurate shooting would be accepted as a warranty issue?
