Huben pistol.

[Ezana4CE]

I think Gregory mentioned not going below 100 bar, so that’s what I’m guided by

The JTS 20.73 fit snug, I seat them, and they ‘click’ into place.

I’ll have a try tomorrow with other (heavier) pellets to check. Would be weird if the pellets are causing this right?

This is the first time I notice this FPS changing. I haven’t shot the GK1 for a while, but that shouldn’t be the issues either I guess..

Very curious about this

@PCPFanNL I don't shoot down beyond 12-13mpa in .25 caliber. Have you tried not shooting down so low in pressure? 10 mpa is low to me. I'm not saying this is the solution to your problem, but I think it's worth a shot to see if it will make a difference.

¿Alguien sabe qué está pasando aquí?
GK1 (v1) .22. Dispara JTS de 20,73 granos. La precisión es buena (por ahora, la estoy probando a 30 m), pero la curva de velocidad (hacia arriba y hacia abajo) es un poco extraña.

Hace un tiempo, las secuencias de disparos eran constantes y con menos fluctuaciones.:inseguro:

Intenta ponerla entre 750 y 800 pies pero a 300 bar y vuelve a probar con crony, si es una V3 asegúrate de tener bien apretada la pieza del guardamonte donde va el tornillo de potencia, si no se soluciona hay que revisar los muelles de las válvulas. .
Saludos.

20,000 shots through mine now. Replaced one Oring on the screw that controls fill rate, due to a slow leak. Still shoots GTOs with great accuracy.

No. I don’t have a need for suppression. Therefore, no reason to make a PISTOL any longer than need be.

I suppose I struck a nerve there with that statement. Wasn’t my intention for sure. Just an observation really. For a PISTOL, it’s already pretty long. I have no reason to make it longer.

Hi, Dave. We live at 2,450 ASL on the side of Davis Mountain in Western NC - just outside Hendersonville. We're surrounded by dense forest with the nearest neighbors cloaked by trees at 100 yards above and 150 below us. But my GK-1 unsilenced BARKS so loud, they'd think I was shooting a .22 Winmag pistol. With Huben's OEM silencer (very short and light) on it, it's a "Pfffft!" and will not disturb anyone near or far. Not arguing, just me tuppence.

 

[LongJnSilver]

Hi, Dave. FYI. No nerve touched, no offense intended, but, many of us that near live near to, and want to respect others, are not able to fire our HK-1s w/o some form of suppression. And, when all that lovely foilage around our property goes grey and bare of leaves, I'll need the can on even more.
Blessings, Johnny - LongJnSilver

Good to see you’re back!

I decided to revert back to the regular pistol format for a while. Now that I have the T9 I have no need for 2 carbines. It is still my favourite PCP by a mile ^^

 

[JaceSpace1369]

Anybody know what’s going on here?
GK1 (v1) .22. Shooting JTS 20.73 grain. Accuracy is good (testing at 30m for now). But the speed curve (up and down) is kinda weird.

A while back the shot strings where steady with less fluctuation

Your mileage may vary but they don't like being shot below 100-110 bar, also if you want to tighten that spread you'll want to increase the velocity to at least 800fps and work your way up.

 

[beerthief]

LMAO why do you say that?

i have hand pumped to 3000 and that was a bit to much , but then i am 79+

I want to get one but 5000 psi compressor I already have a 4500 psi one

@$p00kygH0ST Yes! Any time he puts out a video I watch it lol. I did like the stock he made, very simple and extremely cheap lol. Unlike our current offering of skeletonstocks , unless you want to wait 3-6 weeks to get one from china.

@Stubbers You need the buck-rail grip/rear pic adapter to fit the skeleton grip. The stock is a 5KU stock skeleton solid buttpad(I ordered the folding buttpad from amazon), the hand guard is the skeleton guard from bravo- 3d. (Which is now on sale, ai ordered it 2-3 days ago for $60 ).

I won't be going for the muzzle break or red dot. I may switch from my current 4-16x44 Vortex to a 4x prism to put it all together but I haven't decided yet. I am currently running a huma mod 30 kevlar version. But I have a printed mod coming from the member who created it for the GK1

So, Jace,
just to be sure:

The skeleton grip you linked* above: Can that be mounted without any monkeying or additional adapters to the GK1 V.3?

Thanks for clarifying.

As far as I know it can be mounted if you have the buck-rail grip/adapter, I havent tried without it. I'll give it a try tomorrow and see how it goes.

It will not be a direct fit, the insert section is much too narrow and short to fit without the buck rail grip adapter.

I just ordered a new Safety Lever for my GK1 from www.homedefence-24.com
...and I got this. An extra Haribo. Made me smile.

 

[JaceSpace1369]

Anyone use these to clean the GK1 Barrel?

 

[JaceSpace1369]

Finally put the GK1 together, the buck-rail pic is too short for my liking so I got a pic riser from monstrum on amazon. It's the same length as m0ist0nes extended cnc adapter. I also put the printed mod from a member and I have to say I like the overall look. The rear pic could be shorter for a cleaned up look but it is what it is.

 

[Ach3r0n]

I wish I didn't see this. Now I want one! But Krazcool will not shipping outside from the US.
