I really like the looks of that receiver end. Gives it that tough as nails look. The fore stock and air tube remind me of a Cricket a little.

Congrats JDH.

I'm hoping to find the schematics for the FC. My sling swivel stud is loose and I'm having difficulty figuring out what size allen screw it is. If I find the FC diagram, I will post it here.

swivel stud,,,my guess is 3 mm

What are your thoughts after owning and shooting for a few months?

 

[jdh2550]

I absolutely love it! (A little disclaimer- this is the most expensive airgun I own) I have shot FX and other high end guns but prefer this, just my preference. 

I've been hunting starlings and groundhogs with very good success. This is a pic of the last groundhog I shot. It was only 55 yards but an offhand shot was easy. Hit him right in the back of his head and he went right down. Since the groundhog hunt i purchased a DonnyFL Sumo in.25 caliber and its super quiet now. Accuracy seems to have gotten even better too!

Awesome shot and rifle! I have seen these taken apart for tuning and the barrels are amazing...like a bull barrel, very well made! The platform is similar to an Impacts also. Fantastic pcp! Enjoy .

I'd be interested in hearing about any tuning knowledge on these if you would like to share

I have a Kozak in .22 and have done nothing to it except air it up and shoot since buying it.



I added a 0db moderator from the get go, and the thing is very quiet shooting Hades. The shorter 0db, not the long one.



The rifle runs out so well, that I have not been inclined to fiddle, tweak, or adjust anything but the height of the cheekpiece.

How difficult is it to make hammer spring adjustments ? Do you have to remove the stock or is it like the Tiapan/Vulcan arrangement?

 

[jdh2550]

Any hammer spring adjustments would require the removal of the stock.

As far as hammerspring adjustment on the FC it can be adjusted without removing the stock with a little modification to the stock. From the factory about half of the hammerspring adjuster is exposed. I take a large round file and file down the very rear of the stock where it covers half of the adjuster. It ends up having almost a 1/2" deep half circle filed out which will then allow you to adjust it without removing the stock.

As far as powertuning, I can take the 550 tactical or FC, without adjusting the reg or the hammerspring adjuster, by cleaning up the internal airflow I can pickup about 90 FPS. On the 450 tactical or FC I can get about a 45 FPS gain just by doing the same things.

I hope that helps.

Thanks

Usually in every air rifle after every shot the regulator pressure will set back to the regulator pressure bar tuned in it in a fraction of second. But in zboria sapsan it takes around 20 secs to get back to 150 bar pressure which I have set. So I cannot fire immediately. Does anyone faced this issue. If so tell me how to rectify it.

My kozac no accurazy
30 meter it's too Bad
What i do ???

 

[jdh2550]

I suspect the with a little practice you can tighten those groups up some . LOL just kidding . I have had my eye on the Zebroia for some time . After seeing your post I could not resist buying the one that was listed on Airgun Warriors . Thanks for forcing me to buy another airgun that I dont need

 

[TN_Yankee]

Don’t want to derail, but what model did you buy?

The same , Kosak FC 550. It is the actual gun used to make the video by Shooter 1712. I asked the seller who lives in PA if he bought it new and he said that he got it from someone that does airgun reviews . Turns out that he and Rick are friends
