Huben Huben GK1 Problem

@WobblyHand This is true and is why the Master Thread contains some of its contents and is open for all to add resources to. I'm pretty sure there is at least one decent tear down video.
Kudos to you for creating the Master Thread! I would have been lost without your curated sources. Honestly, I wouldn't have considered buying a GK1 without something like your thread being online. Thanks again for putting it together.

@WobblyHand You’re welcome. Thanks for participating to help build a useful repository of information.
 
my cure for my .25 pellet jam might not be the thing to do, flip the mag lever and slowly push a 3/16" wooden dowel down the barrel with my left hand until
i feel resistance, then keeping a little pressure on the jam i rotate the magazine with my right hand back an forth very little until it frees up.
Yea that might not be the safest thing to do with air in the reservoir.

Edit: I guess I should’ve asked.
@old goat Do you lose all reservoir pressure when your GK1 jams?

Well as the owner of .177 gk1
fingers crossed,
I have not experienced pellet jam,
and I have probably shot like 1000 plus .177 pellets through my recently acquired gk1,
maybe .25 has some porting issues,
I don’t even know what I just said…
A couple of things...

The 25 and 22 tends to have "jamming " issues with certain pellets and slugs. With pellets, particularly in the 25, anything heavy and too pointed can move too far forward in the magazine. With slugs, anything fitting too loose in the magazine will allow them to move forward enough to cause the jamming.

The other "jamming" issue with the semi auto is when the cylinder air pressure falls below what is required for proper and complete cycling of the action. The only fix for this is for the operator to pay attention to the pressure.

Have ypu tried any long, heavy slugs in your 177 yet?

yeah I don’t let it go below 10mpa,
I do have some 10grain zan’s slugs,
which I have not tried yet because of cold outside.
I am just using 7ish grain for 5-10 meter indoor shooting.
