Steyr LG 110 Hunter

Hi guys

I have a little trouble with my Steyr LG 110 Hunter. When I shoot, the Cocking Lever opens up. At first I thought it was the barrel that does not push back all the way to the cocking probe that seals the transfer port to the barrel. But when I align the barrel after about 100 shots the cocking arm opens up again.



If anyone has any experience with this problem please let me know.



Thank you
