GK1 is a very integrated pistol, so I would be hard to put its action to any other pistol without significant redesign...

You only need to tighten it until it stops leaking. It has an o-ring, so this should happen without it being tighten to the end. If it does not, then you might need to replace the o-ring.

I don't know about GK1. I have an additional screw on my old K1 in front of the torx (although that screw was flat with o-ring and not torx on that version). That screw could be used for power limitation but it was not in my case. It is possible that that screw serves are a transfer port choke to limit the power but I cannot say for sure.

Hi. There are a few ways. 1. You can bleed the whole gun by loosing the top action torx screw. 2. You can go down with regulator pressure by adjusting the regulator until the pressure from the plenum bleeds out (the pressure in the main cylinder still remains at this point), then remove the cylinder - regulator - plenum assembly from the gun, and then open the regulator a little bit to drain out the remaining air form the cylinder.

Thank you.

I like to clean the barrel on all my airguns when they arrive. It is not mandatory but a good practice in general. I would not disassemble it just to clean it though, at least not at first.

If you look at it from the rear of the hammer, clockwise will decrease hammer travel and lower the power. You need to loosen the perpendicular screw first in order to be able to rotate the adjusting screw.

You can adjust hammer travel distance. If you move it backwards (shorter stroke) you will achieve the top of the bell curve at lower pressures and have few more shots. It is hard to say the amount of shots you get on unregulated gun because it all depends on what velocity change you find acceptable.

Zdravo. Piši mi na mail ki je pod kontaktom kanala pa se zmenima.

Thanks for the feedback. I happy that you solved it. Mine did not have any issues. I agree that a product in this price range should not have those problems.

That is hard to say. Both of them are so highly modified by now that I don't know but I would probably not sell ShinSung in a form it is now because it is one of a kind leaver action rifle. If unmodified, I would sell ShinSung in a heartbeat because it has so many flaws...

My shin sung has no modifications but I like it very much, on the other hand the wolverine is a much better quality and shoot great, so I might sell the shin sung since I dont think I will ver do any modos to it, what do you think?

@@FabiánIbarra-n7w Huh, I think it is better that you deice this on your own... It all comes down to which you enjoy more and which you would miss more...

😁

Thanks for the tips

Hm, not sure but if it is for GK1 (pistol), then I would not worry about twist rate unless you are shooting long range with it :)

BTW: for .22 cal, the twist rate is perfectly sufficient for any slugs, even boat tail. Only .25 cal has relatively slow twist that is not that good for slugs. At least that is the case on my K1s and GK1s.

It depends on the gun version and also the slug but in case of mine slugs in the video, .219 is best and also loads best in the magazine. .220 should be just fine as long and you can load them in the magazine without using excessive force.

@gregorkamensek3923 yeah.. .220 seems alittle snug but theyve got the dried bullet sizing lube on them..cant wait to get the .219 sizing bushing to see of any differences..be nice to find a barrel thatll fit with faster rate of twist OR a barrel available, say about 10" to 12" inches for these sbr sub carbine builds for switching out easily for back packing or survival defense type scenerio..the gk1 does have the capability to Expand into a survival, hunting genre of crossover pcp..im already seeing that this pistol can outshoot/ outpower my Walther Reign .22 rifle and ive shot my Walther at beyond 250 yards..the gk1 v3 .22 specimen ive got will shoot a small .35 inch or less 5 shot group at 40 yards off the bench( this being with 14.3gr Crosman Premier hp's and JSB 18.13) and a 3x12x44 scope( with a simple green dot sight itll stay around the same size ragged small hole group of less than 1" at 40 yds also..So, im looking forward to testing at 100 yds..eventually ill get the Huma regulator to install and id bet this pistol will do( just possible) be able to do bench rest accuracy at 100 yards..im up to start a You Tube review channel in the near future, so i hope to post my findings with the GK1 extensively very soon..

@@RaysAirgunsReview I saw this post second... For the projectile length that fit in magazine, the stock twist is perfectly sufficient. With my .22 K1, I am using this same barrel and those slug and they are extremely accurate and perfectly stabilized. It will even stabilize boat tail slugs that require more twist (for example ml V2 slugs or Altaros...). The .25 is more problematic because the barrels I have have only about 26" twist... Those barrels do not stabilize boat tail slugs. Regulator will improve your consistency and accuracy but will reduce the power significantly and also reduce the shot count at same power level. All the best with your KZbin channel :)

You mean how to sight in the open sights?

It is possible that the problem is that o-ring, but I still put bigger probability to the valve even if you don't see that there is anything wrong with it. I never had to remove that seal, but you are right, it is quite risky. There is a similar O-ring on K1 and KG1 that I did had to replace and it was a nightmare. One of my viewers actually made me a tool to for this removal afterwards that is basically a bent needle tip on a longer thicker rod. The trick it to just pierce through the o-ring and not go all the way to the aluminium. But I would still put my bet on the valve. Try to replace that first... BTW: can you hear the leak? If so, odes it sound different at different pressures? Does the sound different after each shot? Also possible is that the o-ring in the chamber where the valve goes in (and the valve spring) is leaking. Actually, that one is higher probability than the one you mentioned as well.

@@gregorkamensek3923 Thank you for your reply. I can gear the leak, less noisy at the begining but becoming louder and constand after I take a few more of shots. No difference at different bottle pressures until the bottle is completely empty

@@andreascharalambous6992 OK. that helps. Can you also check to what pressure the regulated pressure raises? It is possible that if the pressure does not get high enough that the valve does not seal... You should get to at least about 150 bars, then dry fire it a few times. This helps the valve to properly seat. All this is with assumption that the valve is not sealing which most likely scenario. If you have possibility, try to get another valve and when you replace it also replace the o-ring in the valve chamber...

@gregorkamensek3923 thanks Gregor, this means that I shall have to increase the reg. pressure to 150 bar or higher. I shall do as you recommend, let us hope it works.

😆. Will do :)

👍

Perfect size for the latest magazines of K1 and GK1 that I have see till now is about .2185 (5.55mm) but if the slug has rings and they have relatively small surface area and/or if it is relatively soft lead, then you can still push them in. My casted slugs from mold V2 (this video) fit just fine. V1 slugs do not. V3 slugs need to be sized to 5.55 mm as explained in the video.

Hi. Unfortunately, I did not make a video for Priest 2 but the guns are virtually the same, the big difference is that Prophet 2 and 3 have pressure assisted valve...

Thanks

Yes, I will at some point

@ awesome dude

Hi. At some point, I will be doing a general tuning video, for all calibers.

@@gregorkamensek3923 i look forward to it, thanks

I don't have any suggestion regarding rear sight. I am also not using this rifle with original stock anymore. This is what this gun look like now: kzbin.info/www/bejne/rImVlXl6o8uVjNE&t
