Sweet, thanks!
 
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 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.
 
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
