Hey guys! I was testing ammo yesterday. Noticed it started hissing when I would pull cocking lever back. If open it’s hissing. Shot few more shots notice it getting worse. Two days before this. My regular stuck and I had to degas my gun. Adjust regular all the way out and made couple turns in to get it to start working again. Still waiting on response from talon tunes. To see if I should be having this many problems from a two month old gun. Any ideas on how to fix? Hopefully just an oring deal. But someone on here said might be valve issue. How do you test to find out? Thanks for info! Hope everyone has blessed day!
