Just got my new Uragan 2 600 from Krale today. Swapped the side lever over and went to fill it (it arrived empty). Air was coming out of the barrel. I took it apart somewhat and yep, air coming up through the transfer port. Obviously a valve problem. Have any of you U2 owners come across this?…….and yes, I did try filling with the gun cocked, same problem.
Brand New U2 Problem

I had a similar issue when I was tuning mine. First time I just had to dry fire it a few times to get everything to seat correctly and leave it cocked. The second time I just needed to cock the rifle and fill it.

Without air I couldn’t do any dry firing though. Wondering if I should dry fire it WHILE the compressor is filling it? Or is that just a terrible idea, lol

The idea is to get the hammer to hit the valve. That should help set it better. Mine was empty when I did that and it worked perfectly

Yeah, same situation with Uragan .25 and U2 .30. There's a thread on this in the archives, posted a picture of set-up used to bump stock end on book (gun cocked) while filling with Yong Heng, heard a click, leak stopped, filling began. My Yong Heng is on a shelf, so had to use longer fill whip, then place heavy book on stool. WM

We had the same problem with my sons pcp . Had him dry fire it then I slapped it around a bit and it sealed.

With my first gen Uragan, I just had to cock the gun. Then fill from empty. Once filled above ~100 bar, all was well....so decock and complete filling.

Blip it with a air tank. This is common for pcp's when out of air actually. Just open the tank valve quickly allowing a large quick burst of air with the hammer cocked and that should seal it as well as dry firing , as others have stated, once it actually starts filling.

Gentlemen, thank you one and all. The Uragan 2 is back in business. Used a combo of tactics as it was filling (rubber mallet, dry fire, bumped the butt end on my bench mat) and it holds air now! I appreciate all of your input, fellas
